How to get route name in htmlhelper?

Question

I want to get the current route name in my html helper but I don't know how to make it.

I thinks the solution is in this post post but I don't know how to create the RouteCollectionExtions.

For the moment my code is:

 using System; using System.Collections.Generic; using System.Globalization; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Routing; public static class RouteCollectionExtensions { public static Route MapRouteWithName(this RouteCollection routes, string name, string url, object defaults, object constraints) { Route route = routes.MapRoute(name, url, defaults, constraints); route.DataTokens = new RouteValueDictionary(); route.DataTokens.Add("RouteName", name); return route; } } public class RouteConfig { public static void RegisterRoutes(RouteCollectionExtensions routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute("favicon.ico"); // Default routes.MapRoute ("Default", "", new { controller = "Home", action = "Index", id = UrlParameter.Optional }); outes.MapRouteWithName("HomeFr", "fr", new { controller = "Home", action = "Index" }); } } 

Do you know why the compiler says:

'MyNamespace.RouteCollectionExtensions' does not contain a definition for 'MapRoute' and the best extension method overload 'System.Web.Mvc.RouteCollection.Extensions.MapRoute(System.web.Routing.RouteCollection, string, string, string[])' has some invalid arguments.

Thanks you for your help. Regards,

In order to use the link you suggested, this is how your RouteConfig should look like:

(I dropped the constraints, because I didn't see he's using it in the example)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
namespace MvcApplication1
{
    public static class RouteCollectionExtensions
    {
        public static Route MapRouteWithName(this RouteCollection routes, string name, string url, object defaults)
        {
            Route route = routes.MapRoute(name, url, defaults);
            route.DataTokens = new RouteValueDictionary();
            route.DataTokens.Add("RouteName", name);

            return route;
        }
    }


    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.MapRouteWithName(
                "myRouteName",
                "{controller}/{action}/{username}",
                new { controller = "Home", action = "List" }

                );
        }
    }
}
