C# code

注册路由：[size=12px][/size]
public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.MapRoute(
                "default", // Route name
                "{controller}/{action}/{id}", // URL with parameters
                new { controller = "Home", action = "index", id = UrlParameter.Optional } // Parameter defaults
            );
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                "Announce",      // Route name  
                "{controller}/{action}/{name}", // URL with parameters
                new { controller = "Announce", action = "Index", name = "" }  // Parameter defaults
           );
        }
action：
  public ActionResult Index()
  {
            return Redirect("http://www.baidu.com");
  }

请求 http://localhost:6389/Announce/List/2 找不到文件

------解决方案--------------------
controller" Announce "里加了
public void List(int id)
{
}

这个方法吗？
------解决方案--------------------
routes.MapRoute(
"Announce", // Route name
"{controller}/{action}/{name}", // URL with parameters
new { controller = "Announce", action = "Index", name = "" } // Parameter defaults
);
自己配置的路由放在default的上面 路由解析规则是从上往下解析的
------解决方案--------------------
controller"Announce"里
public void List(int id)
{
}
或
public void List(int name){}
------解决方案--------------------
你换个顺序试试啊 
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "index", id = UrlParameter.Optional } // Parameter defaults
);
}

------解决方案--------------------
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "index", id = UrlParameter.Optional } // Parameter defaults
);
}

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

routes.MapRoute(
"Announce", // Route name
"{controller}/{action}/{name}", // URL with parameters
new { controller = "Announce", action = "Index", name = "" } // Parameter defaults
);

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"default", // Route name
