如何在 htmlhelper 中获取路由名称？

Question

我想在我的 html 助手中获取当前路线名称，但我不知道如何实现。

我认为解决方案在此 post post 但我不知道如何创建 RouteCollectionExtions。

目前我的代码是：

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" });
        }
    }

你知道为什么编译器说：

'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.

感谢您的帮助。此致，

为了使用您建议的 link，您的 RouteConfig 应该如下所示：

（我放弃了约束，因为我没有看到他在示例中使用它）

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" }

                );
        }
    }
}
