ASP.NET-MVC . How to get the controller name from an url? - asp.net-mvc

Question

How can I get the controller name of a relative Url, using the routes I have defined in Global.asax?
Example:
if I have a route defiend like this:
routes.MapRoute(
"Default", // Route name
"{language}/{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "", language = "en" }
from the string "~/en/products/list" I want to have products (the controller name). Is there any existing method that already does this?

Answer 1

You should probably add another route like George suggests but if you really just need the controller value derived from the route you can do this in your controller action methods:
var controller = (string)RouteData.Values["controller"];

Answer 2

See Stephen Walther's blog post ASP.NET MVC Tip #13 – Unit Test Your Custom Routes
The project MvcFakes has an old System.Web.Abstractions reference. So you must replace it
with the new one and recomply the project to get MvcFakes.dll.
This is my code:
public string getControllerNameFromUrl()
{
RouteCollection rc = new RouteCollection();
MvcApplication.RegisterRoutes(rc);
System.Web.Routing.RouteData rd = new RouteData();
var context = new FakeHttpContext("\\" + HttpContext.Request.Url.AbsolutePath);
rd = rc.GetRouteData(context);
return rd.Values["action"].ToString();
}
In my code above "MvcApplication" is the class name in the Global.asax.
Good luck !

I'm not sure what you're asking, so if my answer's wrong, it's because I'm guessing at what you want.
You can always add another route to your Global.asax. That's often the easiest way to deal with cases 'outside of the norm'.
If you want to return a list of products, you'll use this route:
routes.MapRoute(
"ProductList",
"{language}/{products}/{action}/",
new { controller = "Products", action = "List", language = "en" });
You can also replace products with the more generic {controller} if more than one type of entity is going to use this route. You should modify it for your needs.
For example, to make this a generic route that you can use to get a list of any product:
routes.MapRoute(
"ProductList",
"{language}/{controller}/{action}/",
new { controller = "Products", action = "List", language = "en" });
What this does is that it creates a route (that you should always place before your Default route) that says, "For whatever the user enters, give me the controller and action they ask for". (Such as /en/Products/List, or /en/Users/List).
To visit that controller, you simply need to navigate to the following: yoursite.com/en/products/list. You can also use the HTMLActionLink to visit the controller.
<%=Html.ActionLink("Product", "List", new { controller = Products }, null ) %>
I'm writing this without my IDE open, so the ActionLink may have an error in it.
