路由如何生成URL

 
 public class MyRoute : RouteBase
    {         
        public override RouteData GetRouteData(HttpContextBase httpContext)
        {
            RouteData route = new RouteData(this, new MvcRouteHandler());
            route.Values.Add("Controller", "Home");
            route.Values.Add("Action", "Index");
            return route;
        }

        public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
        {
            if (values.ContainsKey("controller") && (string)values["controller"] == "Home" && values.ContainsKey("action") && (string)values["action"] == "Index")
            {
                return new VirtualPathData(this, "myurl/home/index");//生成自定义URL
            }
            else
            {
                return null;
            }
        }
    }
