未找到視圖“索引”或其主視圖。

The view 'Index' or its master was not found. The following locations were searched:
~/Views/ControllerName/Index.aspx
~/Views/ControllerName/Index.ascx
~/Views/Shared/Index.aspx
~/Views/Shared/Index.ascx

使用 ASP.Net mvc 區域時出現此錯誤。區域控制器操作被呼叫，但它似乎在“基礎”項目視圖中而不是在區域視圖文件夾中查找視圖。

問題是我使用MvcRoute.MappUrlfromMvcContrib來路由context.Routes.

路由映射器似乎對MvcContrib區域路由感到不舒服。

您需要做的是為您的區域名稱設置一個令牌：

例如：

context.MapRoute(
       "SomeArea_default",
       "SomeArea/{controller}/{action}/{id}",
       new { controller = "SomeController", action = "Index", id = UrlParameter.Optional }
   ).DataTokens.Add("area", "YOURAREANAME");
