Asp.net Mvc路由不起作用

Question

I have the following route on my mvc 5 project. When I try to access to the action by url, it throws an 404 error page. What am I doing wrong?

RouteConfig.cs

  .... 
routes.MapRoute
       (
              name: "EventMoneyMovements2",
              url: "eventos/{eventID}/movimientos",
              defaults: new { controller = "EventMoneyMovements", action = "ListByEvent", eventID = UrlParameter.Optional }

       );

Controller

public class EventMoneyMovementsController : Controller
    {
        //
        // GET: /EventMoneyMovements/

        public ActionResult Index()
        {
            return View();
        }

        public ActionResult ListByEvent(int? eventID)
        {

            return View();
        }

    }

The order in which you are registering the routes matters. You should always register your specific routes before the generic default route .

Assuming you register your specific route before your generic like below.

public static void RegisterRoutes(RouteCollection routes)
{
   routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
   routes.MapRoute
   (
          name: "EventMoneyMovements2",
          url: "eventos/{eventID}/movimientos",
          defaults: new { controller = "EventMoneyMovements", action = "ListByEvent",
                                                         eventID = UrlParameter.Optional }

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

With this definition you can access the ListByEvent action method with the request url

yourSiteName/eventos/101/movimientos or yourSitename/EventMoneyMovements/ListByEvent?eventID=101 where 101 is any int value

You must define your custom route before default MVC route because all routes defined in route config maintained in a route table in same order as we define in route config.
