What did I do http://localhost:11111/ doesn't work but http://localhost:11111/Home does? I've already tried Tools> Options > Open to start page and default start page
I think there's something wrong with routing. Check RouteConfig - there must be default route:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
pay attention on controller in defaults.
I need to provide language specific routes for my Asp.Net MVC application. The language should be part of the Url Path (http://myapp/en/Blog) and when it is ommitted the default language have to be used.
http://myapp/en/Blog -> Blog in the English version
http://myapp/Blog -> Blog in the Default (portuguese) Language version
To address this issue I created two Routes bellow:
routes.MapRoute(
name: "Default.lang",
url: "{lang}/{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
constraints: new { lang = #"^[a-zA-Z]{2}$" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
The routes are working as expected but I'm getting weird results when I try to use the Url.RouteUrl method to get alternative language urls.
Example 1 - Path: /
url.Action("Index", "Blog") // returns "/Blog" that is OK
url.Action("Index", "Blog", new { lang = "en" }); // returns "/en/Blog" that is also OK
Example 2 - Path: /en
url.Action("Index", "Home") // returns "/en/Blog" (??????????) Not OK
url.Action("Index", "Home", new { lang = "en" }); // returns "/en/Blog" that is OK
As you can see I get a wrong result when I access the url http://myappurl/en and try to use the Url.Action method without pass any route value (same result with Url.RouteUrl)
Does anyone knows what is wrong with my routes?
[EDIT] I'm not sure if the issue is related to the route because I've tested the routes using "en" as first route's constraint and I got the same result.
After some digging inside System.Web.Mvc and System.Web.Routing source code I found that this behavior is expected. I presume that it is designed to correctly work in applications running inside Virtual Directories.
This can be confirmed in this answer that I found when was researching if someone else had the same problem with virtual path and route resolution.
Workaround
Use named route resolution with Url.RouteUrl method that has and different implementation and works as expected.
Example:
var blogDefaultUrl = url.RouteUrl("Default", new {action = "Index", controller = "Blog"});
var blogLangageSpecifictUrl = url.RouteUrl("Default.lang", new { action = "Index", controller = "Blog", lang = language });
I was avoiding to use named routes because my application design is a little bit more complicated than I demonstrated above. By this reason I have to discover at run time the route that matches the Request.Url and from that point I call the RouteUrl to get the alternative languages url to the content.
Recently, we've understood that Googlebot has faced 593 server errors in our website. After looking at the links, we understood that instead of id in our route, "index.html" is added.
These is the routes of our site:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
routes.MapRoute(
name: "NewsView",
url: "news/{year}/{mounth}/{title}/{id}",
defaults: new { controller = "Home", action = "NewsView" }
);
We have generated the links as below:
#item.Title
This is our website's URL, of course as a sample:
http://www.ourwebsite.com/news/2016/01/this-is-the-title/14747
And this is the URL that Googlebot has faced:
http://www.ourwebsite.com/news/2016/01/this-is-the-title/index.html
In addition, in the "Linked from" tab of Google webmaster, there is the correct URL, which means that the corrupted URL has been linked from the same page with correct URL.
Also, we are using Microsoft URL Rewrite extension, which we have checked and has no rule for this.
Any Help would be highly appreciated
I'm brand new to MVC so please bear with me as I'm only on the second page of the MS Tutorial (see last code example). For the HelloWorldController the following MapRoute is added:
routes.MapRoute(
name: "Hello",
url: "{controller}/{action}/{name}/{id}");
I'm just wondering, is it purely the pattern matching that does the work and the name "Hello" is just for my own reference? If so, are there not naming conventions that should be followed saying the MapRoute should be called HelloWorldWelcome, where welcome is a method inside the HelloWorldController.cs (see above link). Or am i being pedantic?
The route name is also used by the UrlHelper class. For example:
var url = Url.Route("Hello", new
{
controller = "SomeController",
action = "SomeAction",
name = "charlie",
id = 123
});
This will generate a matching URL.
This feature is much more useful when you use Attribute Routing. For example, if on some controller you have an action:
[RoutePrefix("api/phonebook")]
public class PhonebookController
{
[HttpGet("contact/{id}", Name = "GetContact")]
public Contact GetContact(int id)
{
...
}
}
In other code you could use Url.Route("GetContact", new { id = 7 }) to generate the URL /api/phonebook/contact/7.
Please refer to details on ASP.NET MVC Routing Overview
Name attribute is for callign a route from your views or controller with route name.
From ActionLink your can use a routename:
Html.RouteLink("link_text", "route_name", route_parameters)
The question seems to be not so clearly answered (how the "Hello" route is choosen by the "HelloWorld" controller?), but as an Asp.Net MV5 begginer, I can see that the route is selected by default according to the match between the router url property and the URL parameters.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "ImageScan", action = "ScanImage", id = UrlParameter.Optional },
namespaces: new[] { "WebApplication3.Controllers" }
);
I am finding error :
Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.
Requested URL: /Views/ImageScan/ScanImage.cshtml
I am running into the following error with my ASP.NET MVC 3 project:
Multiple types were found that match
the controller named 'Home'. This can
happen if the route that services this
request ('Home/{action}/{id}') does
not specify namespaces to search for a
controller that matches the request.
If this is the case, register this
route by calling an overload of the
'MapRoute' method that takes a
'namespaces' parameter.
The request for 'Home' has found the
following matching controllers:
MyCompany.MyProject.WebMvc.Controllers.HomeController
MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController
I have a HomeController in my default controller folder, with a class name of MyCompany.MyProject.WebMvc.Controllers.HomeController.
My RegisterRoutes method, in my global.asax, looks like:
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
);
}
I then have an area called Company, with a HomeController in the default controller folder for the area, with a class name of MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController.
The RegisterArea method in the CompanyAreaRegistration file looks like:
public override void RegisterArea(AreaRegistrationContext context)
{
context.MapRoute(
"Company_default",
"Company/{controller}/{action}/{id}",
new { area = "Company", action = "Index", id = UrlParameter.Optional }
);
}
This is all leading the error I highlighted at the beginning of this post. I am struggling trying to piece together a solution from various other posts, with NO LUCK.
Is it possible to have a HomeController in the default controllers folder and then one in EACH area? If so, do I need to make (assuming I do) changes to my configuration file to make this work?
Any help would be much appreciated!
The error message contains the recommended solution: "If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter."
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults
new string[] { "MyCompany.MyProject.WebMvc.Controllers"}
);
This will make http://server/ go to your HomeController's Index action which is, I think, what you want. http://server/company/home will go to the Company area's HomeController's Index action, as defined in the area registration.
This is the asp.net mvc4 approach:
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "RegisterNow", id = UrlParameter.Optional },
namespaces: new[] { "YourCompany.Controllers" }
);
I had renamed the namespaces, so, i only delete de folders bin and obj and rebuild, work again.
If you're using RazorGenerator, just informing the namespaces parameter could be not enough.
I got to solve adding the statement marked below at Global.asax.cs:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
ControllerBuilder.Current.DefaultNamespaces.Add("MyProject.Controllers"); // This one
}
Another plausible cause of this issue could be found below:
Multiple types were found that match the controller named 'Home'
use this
routes.MapRoute(
"Default",
"{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new[] { "ProjectName.Controllers" }
);
Use only the name of the project:
Public Class RouteConfig
Public Shared Sub RegisterRoutes(ByVal routes As RouteCollection)
routes.IgnoreRoute("{resource}.axd/{*pathInfo}")
routes.MapRoute( _
name:="Default", _
url:="{controller}/{action}/{id}", _
defaults:=New With {.controller = "Home", .action = "Index", .id = UrlParameter.Optional} _
, namespaces:={"MvcAreas"})
End Sub
I had the same issue and found that the older version had created compiled files in the "bin" folder.
Once I deleted these the error disappeared.
As Chris Moschini mention the namespaces parameter may not be enough if you have two areas with same controller name with different namespaces and the default none area route will return 500 server error.
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults
new string[] { "MyCompany.MyProject.WebMvc.Controllers"}
);
It "best" to override the default route handler and add this line:
RequestContext.RouteData.DataTokens["UseNamespaceFallback"] = false;
I had this issue after I added a reference to another project that had the same routes and the problem continued after I removed the reference.
Resolved by deleting the .dll file of that added reference from the bin folder and rebuilding.
Like many others, I had this problem after creating a new MVC template project from VS2017 menu, on building the project I would get the op's error message. I then used the answer https://stackoverflow.com/a/15651619/2417292 posted earlier in this thread by cooloverride
for mvc4 projects.
This still didn't fix my issue so I renamed my Home view folder and HomeController file to be the view folder Company/ and controller file CompanyController. This then worked for me, not a fix per say but a workaround if your not stuck on having the route Home/Index my other issue was I couldn't find the reference causing the error and due to my dev platform being Azure WebApplication vs a full VM with a complete file system and IIS settings to mess with.
For MVC5 below code works for issue same controller name for different areas. You have to specify which area controller have to hit first.
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new[] { "ApplicationName.Areas.AreaName.Controllers" }
).DataTokens.Add("area", "AreaName");
This issue occurred when I accidentally added
[Route("api/[controllers]s")]
instead of
[RoutePrefix("api/[controllers]s")]
to the top of my ApiController.
