页面的路由限制

Question

如何使用regex限制路由以转到“联系”页面。如下所示

 routes.MapRoute(
               "Default22",
               "{name}",
               new
               { controller = "Home", action = "Contact" },
                new { name = "Contact" });

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

            routes.MapRoute("root9",
            "{controller}/{action}/{footer}",
            new { controller = "FooterMenu", action = "Index" },
            new { id = @"\d+" });

            routes.MapRoute("root8",
             "{controller}/{action}/{header}",
             new { controller = "HeaderMenu", action = "Index" },
             new { id = @"\d+" });

            routes.MapRoute("root7",
              "{controller}/{action}/{id}",
              new { controller = "Admin", action = "Index" },
              new { id = @"\d+" });

            routes.MapRoute(
               "Default1",
               "{name}",
               new
               {
                   controller = "Home",
                   action = "Page"
               }
           );

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

            routes.MapRoute(
                      "Default22", // Route name
                      "{controller}/{action}/{id}", // URL with parameters
                      new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults
                  );
        }
