MVC 控制器分组开发问题

“/”应用程序中的服务器错误。
--------------------------------------------------------------------------------
 未找到视图“MyIndex”或其母版视图。搜索了以下位置: 
~/Views/MyStruct/MyIndex.aspx
~/Views/MyStruct/MyIndex.ascx
~/Views/Shared/MyIndex.aspx
~/Views/Shared/MyIndex.ascx 
上面是我出现的问题，很明显是找不到资源，我检查了很多遍，也没有找出问题，我测试了几遍，可能是解析引擎的问题，但是我没能够找出来，请高手指教
一下是我的部分源代码
global中的代码
 public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            routes.CreateArea("Blogs", "MvDestoryTheConstruct.Areas.Blogs.Controllers", routes.MapRoute(
                null,
                "Blogs/{controller}/{action}/{id}", // 带有参数的 URL
                new { controller = "MyStruct", action = "Index", id = UrlParameter.Optional }));
        }        protected void Application_Start()
        {
            ViewEngines.Engines.Clear();
            ViewEngines.Engines.Add(new AreaViewEngine());
           
            //AreaRegistration.RegisterAllAreas();            RegisterRoutes(RouteTable.Routes);                   }
我自定义的方法
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Routing;namespace MvDestoryTheConstruct
{
    //新建路由设置拓展方法
    public static class AreaRouteHelp
    {
        public static void CreateArea(this RouteCollection routes, string areaName, string controllersNamespace, params Route[] routeEntries)
        {
            foreach (var route in routeEntries)
            {
                if (route.Constraints == null)
                {
                    route.Constraints = new RouteValueDictionary();
                }
                if (route.DataTokens == null)
                {
                    route.DataTokens = new RouteValueDictionary();
                }
                if (route.Defaults == null)
                {
                    route.Defaults = new RouteValueDictionary();
                }
                route.Constraints.Add("area", areaName);
                route.Defaults.Add("area", areaName);
                route.DataTokens.Add("namespaces",new string[]{controllersNamespace});
                //将路由添加到路由表中
                if (!routes.Contains(route))
                {
                    routes.Add(route);
                }
            }
            
        }
    }
}这是我自定义的解析引擎
