Is it possible to use the first code to then add it to the Global file (second code)? I can't seem to get it to work. I want to display string user from the second code in the global.asax.
Thanks,
EB
void Session_Start(object sender, EventArgs e)
{
string username = HttpContext.Current.User.Identity.Name;
Session["Username"] = username;
}
Add This:
using (var context = new PrincipalContext(ContextType.Domain, "Domain.local"))
{
var user = UserPrincipal.FindByIdentity(context, username);
}
You can use User.Identity.Name both in Controller and Global.asax.cs.
This User comes from Base Controller Class which in inherited by your custom controller.
If you want to get names in your plain class files you can use these:
System.Security.Principal.WindowsIdentity.GetCurrent().Name
System.Web.HttpContext.Current.User.Identity.Name
In layout I am using this:
<a href="#" id="userRole">
<i class="fas fa-user" style="font-size:14px;"></i> #Business.FindPersonByMSID(User.Identity.Name.Substring(3))
</a>
You can use
#if(User.Identity.Name) in .cshtml anywhere.
Business.FindPersonByMSID is a static method in my Business class I am using to get the Full name of the person by his MSID or NTID .
You did not ask for below code but it will give you full view of what I am doing.
public static string FindPersonByMSID(string msid)
{
string displayName = "";
if (msid.Trim() != "")
{
DirectorySearcher searcher = new DirectorySearcher();
searcher.Filter = string.Format("(&(objectCategory=person)(objectClass=user)(cn={0}))", msid);
SearchResult allResults;
allResults = searcher.FindOne();
DirectoryEntry deMembershipUser = allResults.GetDirectoryEntry();
deMembershipUser.RefreshCache();
displayName = (string)deMembershipUser.Properties["displayname"].Value;
}
return displayName;
}

Into class I get logged user like
public static GetUserById_Result GetUser(string userId)
{
GetUserById_Result user = new GetUserById_Result();
try
{
using (EF.SSMA oContext = new EF.SSMA())
{
user = oContext.GetUserById(userId).FirstOrDefault();
}
}
catch (Exception)
{
throw;
}
return user;
}
So it runs fine. But in the same class I want to acces user value into another method
public static List<GetUsers_Result> SelectAll()
{
List<GetUsers_Result> lstResult = new List<GetUsers_Result>();
try
{
using (EF.SSMA oContext = new EF.SSMA())
{
lstResult = oContext.GetUsers().Where().ToList();
}
}
catch (Exception ex)
{
throw ex;
}
return lstResult;
}
What I need to do to achieve that?, into controller is really simple I just do this:
var users = User.Identity.GetUserId();
GetUserById_Result currentUser = UserClass.GetUser(users);
var role = currentUser.BranchOfficeId;
But how can I acces it in the same class' I try to call GetUserId with
System.Web.HttpContext.Current.User.Identity.GetUserId();
but it just mark HttpContext in red and say "Cannot resolve symbol 'HttpContext'"
My target is to call only users who BranchOfficeId = user.BranchOfficeId
Help is very appreciated. Regards
If i understand your question well, make sure that you already installed the package Microsoft.Owin.Host.SystemWeb and add using System.Web, then use directely User.Identity.GetUserId()
The reason you can do this in the controller is because Controller has an HttpContext property, which has been created with the details of the current request, including the identity of the current user.
If you want to access the user from another class, you need to pass the user as an argument to your method. As an example:
using System.Security.Principal;
public class SomeClass
{
public void SomeMethod(IPrincipal user)
{
// Whatever you need
}
}
Then in your controller:
var someClass = new SomeClass();
someClass.SomeMethod(HttpContext.User);
However, if you're only interested in the user's name, then you can actually just pass a string instead:
public class SomeClass
{
public void SomeMethod(string username)
{
// Whatever you need
}
}
Then in your controller:
var someClass = new SomeClass();
someClass.SomeMethod(HttpContext.User.Identity.Name);
I'm just getting started with MVC5 (from WebForms), and dropdownlist bindings are giving me some fits.
I'd like to get this working using a GET request back to the page, with a selected value parameter. I'm hopeful that I can specify the route arguments in the form itself, so I'd like to reference the DDL's SelectedValue.
<p>
#using (Html.BeginForm("Index", "Profile", FormMethod.Get, new { id = WHATDOIPUTHERE} )) {
#Html.AntiForgeryToken()
#Html.DropDownList("ApplicationID", new SelectList(ViewBag.ApplicationList, "ApplicationID", "ApplicationName", ViewBag.SelectedApplicationId), new {onchange = "this.form.submit();"})
}
</p>
I can make it work with a POST form, but that requires a second controller method so I end up with
public ActionResult Index(long? id) {
ConfigManager config = new ConfigManager();
//handle application. default to the first application returned if none is supplied.
ViewBag.ApplicationList = config.GetApplications().ToList();
if (id != null) {
ViewBag.SelectedApplicationId = (long)id;
}
else {
ViewBag.SelectedApplicationId = ViewBag.ApplicationList[0].ApplicationID; //just a safe default, if no param provided.
}
//handle profile list.
List<ProfileViewModel> ps = new List<ProfileViewModel>();
ps = (from p in config.GetProfilesByApp((long)ViewBag.SelectedApplicationId) select new ProfileViewModel(p)).ToList();
return View(ps);
}
//POST: Profile
//read the form post result, and recall Index, passing in the ID.
[HttpPost]
public ActionResult index(FormCollection collection) {
return RedirectToAction("Index", "Profile", new {id = collection["ApplicationId"]});
}
It would be really nice to get rid of the POST method, since this View only ever lists child entities.
What do you think?
You can update your GET action method parameter name to be same as your dropdown name.
I also made some small changes to avoid possible null reference exceptions.
public ActionResult Index(long? ApplicationID) {
var config = new ConfigManager();
var applicationList = config.GetApplications().ToList();
ViewBag.ApplicationList = applicationList ;
if (ApplicationID!= null) {
ViewBag.SelectedApplicationId = ApplicationID.Value;
}
else
{
if(applicationList.Any())
{
ViewBag.SelectedApplicationId = applicationList[0].ApplicationID;
}
}
var ps = new List<ProfileViewModel>();
ps = (from p in config.GetProfilesByApp((long)ViewBag.SelectedApplicationId)
select new ProfileViewModel(p)).ToList();
return View(ps);
}
I am using Rotativa tool to display pdf. It works fine with the following code:
public ActionResult PreviewDocument()
{
var htmlContent = Session["html"].ToString();
var model = new PdfInfo { Content = htmlContent, Name = "PDF Doc" };
return new ViewAsPdf(model);
}
I wanted to know the way to download the pdf via browser's "save as" dialog on clicking on a button and not to display in some iframe. "new ViewAsPdf(model)" just returns the pdf data.
Thanks in advance.
You can add additional attributes to the Rotativa call like this:
return new PartialViewAsPdf("PreviewDocument", pdfModel)
{
PageSize = Size.A4,
FileName = "PDF Doc.pdf"
};
And it'll create the file for you. :)
I finally got a way to do this.
Actually rotativa's method "return new ViewAsPdf(model)" returns HttpResponseStream. Where we can hardly do something. But we can modify/alter the response once the action get executed by using custom attribute. We can override OnResultExecuted() method of action filter.
Controller's action
[HttpGet]
[ActionDownload] //here a custom action filter added
public ActionResult DownloadDocument()
{
var htmlContent = "<h1>sachin Kumar</hi>";
var model = new PdfInfo {FtContent = htmlContent, FtName = "Populate Form"};
return new ViewAsPdf(model);
}
Custom Action filter:
public class ActionDownloadAttribute : ActionFilterAttribute
{
public override void OnResultExecuted(ResultExecutedContext filterContext)
{
//Add content-disposition header to response so that browser understand to download as an attachment.
filterContext.HttpContext.Response.AddHeader("content-disposition", "attachment; filename=" + "Report.pdf");
base.OnResultExecuted(filterContext);
}
}
You can use return new ActionAsPdf. No custom attributes or anything else required.
Example: https://github.com/webgio/Rotativa/
public ActionResult PrintPreviewDocument()
{
return new ActionAsPdf("PreviewDocument") { FileName = "PDF Doc.pdf" };
}
public ActionResult PreviewDocument()
{
var htmlContent = Session["html"].ToString();
var model = new PdfInfo { Content = htmlContent, Name = "PDF Doc" };
return View(model);
}
I have a User entity, and in various views, I want to create links to a user home page basically. This functionality should be available in different controllers, so I can easily redirect to the user's home page. Each user in my site has a role ; for example reader, writer, editor, manager and admin. Ideally, I want to try to achieve something like this:
In a controller, for example
public ActionResult SomeThingHere() {
return View(User.GetHomePage());
//OR
return RedirectToROute(User.GetHomePage());
}
in a View, I also want to use the same functionality, for example:
<%= Html.ActionLink("Link to home", user.GetHomePage() %>
Is it possible to achieve such a design in MVC? If so , how should I go about it?
I currently use a method like this, but it is only in one controller at the moment. Now I need to use the same code somewhere else and I am trying to figure out how I could refractor this and avoid repeating myself?
....
private ActionResult GetHomePage(User user){
if (user.IsInRole(Role.Admin))
return RedirectToAction("Index", "Home", new { area = "Admin" });
if (user.IsInRole(Role.Editor))
// Managers also go to editor home page
return RedirectToAction("Index", "Home", new {area = "Editor"});
if (user.IsInRole(Role.Reader))
// Writer and reader share the same home page
return RedirectToAction("Index", "Home", new { area = "Reader" });
return RedirectToAction("Index", "Home");
}
...
How about something like this:
private string GetArea(User u)
{
string area = string.empty;
if (User.IsInRole(Admin)) area = "admin";
else if (...)
return area;
}
I would suggest a custom extension to the HtmlHelper class. Top of my head (liable to have syntax errors), something like this
public static class RoleLinksExtension
{
public static string RoleBasedHomePageLink(this HtmlHelper helper, string text)
{
if (user.IsInRole(Role.Admin))
return helper.ActionLink(text, "Index", "Home", new { area = "Admin" });
// other role options here
return string.Empty; // or throw exception
}
}
Then it's just
<%= Html.RoleBasedHomePageLink("Link to home") %>
in your markup.
You don't really want to have a link to somewhere that simply redirects somewhere else, if you can avoid it.
Edit: No idea why I didn't think of this earlier, but if you do need to redirect (perhaps if you need some functionality before going to the home page), you could extend IPrinciple instead
public static class AreaHomePageExtensions
{
public static string GetArea(this IPrinciple user)
{
if (user.IsInRole(Role.Admin))
return "Admin";
// Other options here
}
}
Then you can do
return RedirectToAction("Index", "Home", new { area = User.GetArea() });
whenever you like.
Well I finally came up with a design that seems to work. I have written an controller extension,
with a GetHomePage Method. This extension can also be used in your views. Here is how I did It:
public static class UserHelperExtension {
public static string GetHomePage(this ControllerBase controller, User user) {
return = "http://" + controller.ControllerContext
.HttpContext.Request
.ServerVariables["HTTP_HOST"] + "/"
+ GetHomePage(user);
}
//need this for views
public static string GetHomePage(string httphost, User user) {
return = "http://" + httphost + "/" + GetHomePage(user});
}
private static string GetHomePage(User user) {
if (user.IsInRole(Role.Admin))
return "/Admin/Home/Index";
if (user.IsInRole(Role.Editor))
return "/Editor/Home/Index";
if (user.IsInRole(Role.Reader))
return "/Reader/Home/Index";
return "/Home/Index";
}
}
The action method in the controller looks like this:
using Extensions;
...
public ActionResult SomethingHere() {
return Redirect(this.GetHomePage(user));
}
...
In the view I have this:
...
<%# Import Namespace="Extensions"%>
<%=UserHelperExtension.GetHomePage(Request.ServerVariables["HTTP_HOST"], user)%>
...
The advantage is that I can easily use this "GetHomePage" method in various controllers,
or views thoughout my application, and the logic is in one place. The disadvantage is that
I would have preferred to have it more type safe. For example, in my orignal tests, I had access to RouteValues collection:
public void User_should_redirect_to_role_home(Role role,
string area, string controller, string action) {
...
var result = (RedirectToRouteResult)userController.SomeThingHere();
Assert.That(result.RouteValues["area"],
Is.EqualTo(area).IgnoreCase);
Assert.That(result.RouteValues["controller"],
Is.EqualTo(controller).IgnoreCase);
Assert.That(result.RouteValues["action"],
Is.EqualTo(action).IgnoreCase);
...
}
But now that I am using a string so it is not type safe, and checking the RedirectResult.Url.
...
var result = (RedirectResult) userController.SomethingHere();
Assert.That(result.Url.EndsWith("/" + area + "/" + controller + "/" + action),
Is.True);
...
How can dynamic breadcrumbs be achieved with ASP.net MVC?
If you are curious about what breadcrumbs are:
What are breadcrumbs? Well, if you have ever browsed an online store or read posts in a forum, you have likely encountered breadcrumbs. They provide an easy way to see where you are on a site. Sites like Craigslist use breadcrumbs to describe the user's location. Above the listings on each page is something that looks like this:
s.f. bayarea craigslist > city of san francisco > bicycles
EDIT
I realize what is possible with the SiteMapProvider. I am also aware of the providers out there on the net that will let you map sitenodes to controllers and actions.
But, what about when you want a breadcrumb's text to match some dynamic value, like this:
Home > Products > Cars > Toyota
Home > Products > Cars > Chevy
Home > Products > Execution Equipment > Electric Chair
Home > Products > Execution Equipment > Gallows
... where the product categories and the products are records from a database. Some links should be defined statically (Home for sure).
I am trying to figure out how to do this, but I'm sure someone has already done this with ASP.net MVC.
Sitemap's are definitely one way to go... alternatively, you can write one yourself! (of course as long as standard MVC rules are followed)... I just wrote one, I figured I would share here.
#Html.ActionLink("Home", "Index", "Home")
#if(ViewContext.RouteData.Values["controller"].ToString() != "Home") {
#:> #Html.ActionLink(ViewContext.RouteData.Values["controller"].ToString(), "Index", ViewContext.RouteData.Values["controller"].ToString())
}
#if(ViewContext.RouteData.Values["action"].ToString() != "Index"){
#:> #Html.ActionLink(ViewContext.RouteData.Values["action"].ToString(), ViewContext.RouteData.Values["action"].ToString(), ViewContext.RouteData.Values["controller"].ToString())
}
Hopefully someone will find this helpful, this is exactly what I was looking for when I searched SO for MVC breadcrumbs.
ASP.NET 5 (aka ASP.NET Core), MVC Core Solution
In ASP.NET Core, things are further optimized as we don't need to stringify the markup in the extension method.
In ~/Extesions/HtmlExtensions.cs:
using System.Text.RegularExpressions;
using Microsoft.AspNetCore.Html;
using Microsoft.AspNetCore.Mvc.Rendering;
namespace YourProjectNamespace.Extensions
{
public static class HtmlExtensions
{
private static readonly HtmlContentBuilder _emptyBuilder = new HtmlContentBuilder();
public static IHtmlContent BuildBreadcrumbNavigation(this IHtmlHelper helper)
{
if (helper.ViewContext.RouteData.Values["controller"].ToString() == "Home" ||
helper.ViewContext.RouteData.Values["controller"].ToString() == "Account")
{
return _emptyBuilder;
}
string controllerName = helper.ViewContext.RouteData.Values["controller"].ToString();
string actionName = helper.ViewContext.RouteData.Values["action"].ToString();
var breadcrumb = new HtmlContentBuilder()
.AppendHtml("<ol class='breadcrumb'><li>")
.AppendHtml(helper.ActionLink("Home", "Index", "Home"))
.AppendHtml("</li><li>")
.AppendHtml(helper.ActionLink(controllerName.Titleize(),
"Index", controllerName))
.AppendHtml("</li>");
if (helper.ViewContext.RouteData.Values["action"].ToString() != "Index")
{
breadcrumb.AppendHtml("<li>")
.AppendHtml(helper.ActionLink(actionName.Titleize(), actionName, controllerName))
.AppendHtml("</li>");
}
return breadcrumb.AppendHtml("</ol>");
}
}
}
~/Extensions/StringExtensions.cs remains the same as below (scroll down to see the MVC5 version).
In razor view, we don't need Html.Raw, as Razor takes care of escaping when dealing with IHtmlContent:
....
....
<div class="container body-content">
<!-- #region Breadcrumb -->
#Html.BuildBreadcrumbNavigation()
<!-- #endregion -->
#RenderBody()
<hr />
...
...
ASP.NET 4, MVC 5 Solution
=== ORIGINAL / OLD ANSWER BELOW ===
(Expanding on Sean Haddy's answer above)
If you want to make it extension-driven (keeping Views clean), you can do something like:
In ~/Extesions/HtmlExtensions.cs:
(compatible with MVC5 / bootstrap)
using System.Text;
using System.Web.Mvc;
using System.Web.Mvc.Html;
namespace YourProjectNamespace.Extensions
{
public static class HtmlExtensions
{
public static string BuildBreadcrumbNavigation(this HtmlHelper helper)
{
// optional condition: I didn't wanted it to show on home and account controller
if (helper.ViewContext.RouteData.Values["controller"].ToString() == "Home" ||
helper.ViewContext.RouteData.Values["controller"].ToString() == "Account")
{
return string.Empty;
}
StringBuilder breadcrumb = new StringBuilder("<ol class='breadcrumb'><li>").Append(helper.ActionLink("Home", "Index", "Home").ToHtmlString()).Append("</li>");
breadcrumb.Append("<li>");
breadcrumb.Append(helper.ActionLink(helper.ViewContext.RouteData.Values["controller"].ToString().Titleize(),
"Index",
helper.ViewContext.RouteData.Values["controller"].ToString()));
breadcrumb.Append("</li>");
if (helper.ViewContext.RouteData.Values["action"].ToString() != "Index")
{
breadcrumb.Append("<li>");
breadcrumb.Append(helper.ActionLink(helper.ViewContext.RouteData.Values["action"].ToString().Titleize(),
helper.ViewContext.RouteData.Values["action"].ToString(),
helper.ViewContext.RouteData.Values["controller"].ToString()));
breadcrumb.Append("</li>");
}
return breadcrumb.Append("</ol>").ToString();
}
}
}
In ~/Extensions/StringExtensions.cs:
using System.Globalization;
using System.Text.RegularExpressions;
namespace YourProjectNamespace.Extensions
{
public static class StringExtensions
{
public static string Titleize(this string text)
{
return CultureInfo.CurrentCulture.TextInfo.ToTitleCase(text).ToSentenceCase();
}
public static string ToSentenceCase(this string str)
{
return Regex.Replace(str, "[a-z][A-Z]", m => m.Value[0] + " " + char.ToLower(m.Value[1]));
}
}
}
Then use it like (in _Layout.cshtml for example):
....
....
<div class="container body-content">
<!-- #region Breadcrumb -->
#Html.Raw(Html.BuildBreadcrumbNavigation())
<!-- #endregion -->
#RenderBody()
<hr />
...
...
There is a tool to do this on codeplex: http://mvcsitemap.codeplex.com/ [project moved to github]
Edit:
There is a way to derive a SiteMapProvider from a database: http://www.asp.net/Learn/data-access/tutorial-62-cs.aspx
You might be able to modify the mvcsitemap tool to use that to get what you want.
I built this nuget package to solve this problem for myself:
https://www.nuget.org/packages/MvcBreadCrumbs/
You can contribute here if you have ideas for it:
https://github.com/thelarz/MvcBreadCrumbs
For those using ASP.NET Core 2.0 and looking for a more decoupled approach than vulcan's HtmlHelper, I recommend having a look at using a partial view with dependency injection.
Below is a simple implementation which can easily be molded to suit your needs.
The breadcrumb service (./Services/BreadcrumbService.cs):
using Microsoft.AspNetCore.Mvc.Rendering;
using Microsoft.AspNetCore.Mvc.ViewFeatures;
using System;
using System.Collections.Generic;
namespace YourNamespace.YourProject
{
public class BreadcrumbService : IViewContextAware
{
IList<Breadcrumb> breadcrumbs;
public void Contextualize(ViewContext viewContext)
{
breadcrumbs = new List<Breadcrumb>();
string area = $"{viewContext.RouteData.Values["area"]}";
string controller = $"{viewContext.RouteData.Values["controller"]}";
string action = $"{viewContext.RouteData.Values["action"]}";
object id = viewContext.RouteData.Values["id"];
string title = $"{viewContext.ViewData["Title"]}";
breadcrumbs.Add(new Breadcrumb(area, controller, action, title, id));
if(!string.Equals(action, "index", StringComparison.OrdinalIgnoreCase))
{
breadcrumbs.Insert(0, new Breadcrumb(area, controller, "index", title));
}
}
public IList<Breadcrumb> GetBreadcrumbs()
{
return breadcrumbs;
}
}
public class Breadcrumb
{
public Breadcrumb(string area, string controller, string action, string title, object id) : this(area, controller, action, title)
{
Id = id;
}
public Breadcrumb(string area, string controller, string action, string title)
{
Area = area;
Controller = controller;
Action = action;
if (string.IsNullOrWhiteSpace(title))
{
Title = Regex.Replace(CultureInfo.CurrentCulture.TextInfo.ToTitleCase(string.Equals(action, "Index", StringComparison.OrdinalIgnoreCase) ? controller : action), "[a-z][A-Z]", m => m.Value[0] + " " + char.ToLower(m.Value[1]));
}
else
{
Title = title;
}
}
public string Area { get; set; }
public string Controller { get; set; }
public string Action { get; set; }
public object Id { get; set; }
public string Title { get; set; }
}
}
Register the service in startup.cs after AddMvc():
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
services.AddTransient<BreadcrumbService>();
Create a partial to render the breadcrumbs (~/Views/Shared/Breadcrumbs.cshtml):
#using YourNamespace.YourProject.Services
#inject BreadcrumbService BreadcrumbService
#foreach(var breadcrumb in BreadcrumbService.GetBreadcrumbs())
{
<a asp-area="#breadcrumb.Area" asp-controller="#breadcrumb.Controller" asp-action="#breadcrumb.Action" asp-route-id="#breadcrumb.Id">#breadcrumb.Title</a>
}
At this point, to render the breadcrumbs simply call Html.Partial("Breadcrumbs") or Html.PartialAsync("Breadcrumbs").
Maarten Balliauw's MvcSiteMapProvider worked pretty well for me.
I created a small mvc app to test his provider: MvcSiteMapProvider Test (404)
For whoever is interested, I did an improved version of a HtmlExtension that is also considering Areas and in addition uses Reflection to check if there is a Default controller inside an Area or a Index action inside a Controller:
public static class HtmlExtensions
{
public static MvcHtmlString BuildBreadcrumbNavigation(this HtmlHelper helper)
{
string area = (helper.ViewContext.RouteData.DataTokens["area"] ?? "").ToString();
string controller = helper.ViewContext.RouteData.Values["controller"].ToString();
string action = helper.ViewContext.RouteData.Values["action"].ToString();
// add link to homepage by default
StringBuilder breadcrumb = new StringBuilder(#"
<ol class='breadcrumb'>
<li>" + helper.ActionLink("Homepage", "Index", "Home", new { Area = "" }, new { #class="first" }) + #"</li>");
// add link to area if existing
if (area != "")
{
breadcrumb.Append("<li>");
if (ControllerExistsInArea("Default", area)) // by convention, default Area controller should be named Default
{
breadcrumb.Append(helper.ActionLink(area.AddSpaceOnCaseChange(), "Index", "Default", new { Area = area }, new { #class = "" }));
}
else
{
breadcrumb.Append(area.AddSpaceOnCaseChange());
}
breadcrumb.Append("</li>");
}
// add link to controller Index if different action
if ((controller != "Home" && controller != "Default") && action != "Index")
{
if (ActionExistsInController("Index", controller, area))
{
breadcrumb.Append("<li>");
breadcrumb.Append(helper.ActionLink(controller.AddSpaceOnCaseChange(), "Index", controller, new { Area = area }, new { #class = "" }));
breadcrumb.Append("</li>");
}
}
// add link to action
if ((controller != "Home" && controller != "Default") || action != "Index")
{
breadcrumb.Append("<li>");
//breadcrumb.Append(helper.ActionLink((action.ToLower() == "index") ? controller.AddSpaceOnCaseChange() : action.AddSpaceOnCaseChange(), action, controller, new { Area = area }, new { #class = "" }));
breadcrumb.Append((action.ToLower() == "index") ? controller.AddSpaceOnCaseChange() : action.AddSpaceOnCaseChange());
breadcrumb.Append("</li>");
}
return MvcHtmlString.Create(breadcrumb.Append("</ol>").ToString());
}
public static Type GetControllerType(string controller, string area)
{
string currentAssembly = Assembly.GetExecutingAssembly().GetName().Name;
IEnumerable<Type> controllerTypes = Assembly.GetExecutingAssembly().GetTypes().Where(o => typeof(IController).IsAssignableFrom(o));
string typeFullName = String.Format("{0}.Controllers.{1}Controller", currentAssembly, controller);
if (area != "")
{
typeFullName = String.Format("{0}.Areas.{1}.Controllers.{2}Controller", currentAssembly, area, controller);
}
return controllerTypes.Where(o => o.FullName == typeFullName).FirstOrDefault();
}
public static bool ActionExistsInController(string action, string controller, string area)
{
Type controllerType = GetControllerType(controller, area);
return (controllerType != null && new ReflectedControllerDescriptor(controllerType).GetCanonicalActions().Any(x => x.ActionName == action));
}
public static bool ControllerExistsInArea(string controller, string area)
{
Type controllerType = GetControllerType(controller, area);
return (controllerType != null);
}
public static string AddSpaceOnCaseChange(this string text)
{
if (string.IsNullOrWhiteSpace(text))
return "";
StringBuilder newText = new StringBuilder(text.Length * 2);
newText.Append(text[0]);
for (int i = 1; i < text.Length; i++)
{
if (char.IsUpper(text[i]) && text[i - 1] != ' ')
newText.Append(' ');
newText.Append(text[i]);
}
return newText.ToString();
}
}
If can definitely can be improved (probably does not cover all the possible cases), but it did not failed me until now.
