mvc routing重新

 

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

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。
