与MVC中的路由相关的问题

Question

I have MVC webapplication. i have written following rules in Route.config file

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
            routes.MapRoute(
              name: "about",
              url: "Home/About-WDI",
              defaults: new { controller = "Home", action = "About"}
            );


        }

and in global.asax file, i have written following code:

RouteConfig.RegisterRoutes(RouteTable.Routes);

now problem is when i type http://localhost:60123/Home/About-WDI it gives me error saying Resources not found

what is issue in above code? Thanks

As already mentioned in the comments, the order of the routes is taken into concern. And as your {id} parameter is optional the URL will be matched by the first route. So simply exchange both routes:

public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.MapRoute(
              name: "about",
              url: "Home/About-WDI",
              defaults: new { controller = "Home", action = "About"}
            );
            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );
        }
