mvc routing重新

using System.Web.Mvc;
using System.Web.Routing;

namespace MyMvc
{
    // 注意: 有关启用 IIS6 或 IIS7 经典模式的说明，
    // 请访问 http://go.microsoft.com/?LinkId=9394801

    public class MvcApplication : System.Web.HttpApplication
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            /*routes.MapRoute(
                "Default", // 路由名称
                "{controller}/{action}/{id}", // 带有参数的 URL
                new { controller = "Home", action = "Index", id = UrlParameter.Optional } // 参数默认值
            );
            */
            routes.MapRoute(
                "Default1", 
                "{controller}/{action}/{id}/{sid}", 
                new{controller = "Home",action = "Index",id = UrlParameter.Optional,sid = UrlParameter.Optional} 
                ); 
        }

        protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();

            RegisterRoutes(RouteTable.Routes);
        }
    }
}

http://localhost/home/index/123/321时，controller="Home", action="Index", id=123, sid=321。如果URL不带可选参数

http://localhost/home/index，这时controller="Home", action="Index", id和sid为空。
