如何选择MVC3

路线我已经有三个途径如何选择MVC3

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



     routes.MapRoute(
      "TestRoute", 
      "{id}", 
      new { controller = "Product", action = "Index3", id = UrlParameter.Optional }, 
      new { id = @"\d+" } //one or more digits only, no alphabetical characters 
     ); 

     routes.MapRoute(
      "TestCatalogRoute", 
      "{id}", 
      new { controller = "Home", action = "Index", id = UrlParameter.Optional } 
     ); 

     routes.MapRoute(
      "Default", // Route name 
      "{controller}/{action}/{id}", // URL with parameters 
      new { controller = "Home", action = "RsvpForm", id = UrlParameter.Optional } // Parameter defaults 
      //new { controller = "Product", action = "Index2", id = UrlParameter.Optional } // Parameter defaults 
     ); 


    }
