试试这个：

   private void RegisterRoutes(RouteCollection routes) {

      routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

      routes.MapRoute("default", "{controller}/{action}/{id}",
         new { action = "index", id = "" },
         // Register below the name of all the other controllers
         new { controller = @"^(account|support)$" });

      routes.MapRoute("home", "{action}",
         new { controller = "device", action = "index" });
   }

例如。 /富

如果富是不是一个控制器，那么它当作的行动装置控制器。

If foo is not a controller then it's treated as an action of the device controller.
