不同區域中的相同控制器名稱

Question

在具有區域的ASP.NET MVC 3應用程序中（請參閱下面的架構）。根目錄下的「控制器」目錄已被刪除。

當我這樣做：

routes.MapRoute(
     "Default", // Route name 
     "{controller}/{action}/{id}", // URL with parameters 
     new { controller = "Home", action = "Index", id = UrlParameter.Optional } // Parameter defaults 
    ); 

我得到這個錯誤： 多種類型的發現命名爲「家」的控制器匹配。 如果爲該請求提供服務的路由（'{controller}/{action}/{id}'） 未指定命名空間來搜索與該請求匹配的控制器，則會發生這種情況。 如果是這種情況，請通過調用帶有'namespaces'參數的'MapRoute' 方法的重載來註冊此路由。 爲 '家' 的請求已發現下列匹配控制器： MyProject.Areas.Administration.Controllers.HomeController MyProject.Areas.BackEnd.Controllers.HomeController MyProject.Areas.FrontEnd.Controllers.HomeController

當我這樣做：

routes.MapRoute(
     "Default", // Route name 
     "{controller}/{action}/{id}", // URL with parameters 
     new { controller = "Home", action = "Index", id = UrlParameter.Optional }, // Parameter defaults 
     new string[] { "MyProject.Areas.Administration.Controllers" } 
    ); 

我得到那朵錯誤：

The view 'Index' or its master was not found or no view engine supports the searched locations. The following locations were searched: 
~/Views/Home/Index.aspx 
~/Views/Home/Index.ascx 
~/Views/Shared/Index.aspx 
~/Views/Shared/Index.ascx 
~/Views/Home/Index.cshtml 
~/Views/Home/Index.vbhtml 
~/Views/Shared/Index.cshtml 
~/Views/Shared/Index.vbhtml

UPDATE1 要開始在區域特定的控制器，我嘗試這樣做：

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

    routes.MapRoute(
     "Default", 
     "{controller}/{action}/{id}", 
     new { controller = "Home", action = "Index", id = UrlParameter.Optional }, 
     new[] { "MyProject.Areas.BackEnd.Controllers" } 
    ); 
} 

Answer 1

嘗試以下操作：

~/Global.asax.cs：

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

    routes.MapRoute(
     "Default", 
     "{controller}/{action}/{id}", 
     new { controller = "Home", action = "Index", id = UrlParameter.Optional }, 
     new[] { "MyProject.Controllers" } 
    ); 
} 

~/Areas/Administration/AdministrationAreaRegistration.cs

public override void RegisterArea(AreaRegistrationContext context) 
{ 
    context.MapRoute(
     "Administration_default", 
     "Administration/{controller}/{action}/{id}", 
     new { action = "Index", id = UrlParameter.Optional }, 
     new[] { "MyProject.Areas.Administration.Controllers" } 
    ); 
} 

~/Areas/FrontEnd/FrontEndAreaRegistration.cs：

public override void RegisterArea(AreaRegistrationContext context) 
{ 
    context.MapRoute(
     "FrontEnd_default", 
     "FrontEnd/{controller}/{action}/{id}", 
     new { action = "Index", id = UrlParameter.Optional }, 
     new[] { "MyProject.Areas.FrontEnd.Controllers" } 
    ); 
} 

現在，當你要求/Administration/Home/Index的HomeController在Administration面積Index動作將被調用，它會尋找~/Areas/Administration/Views/Home/Index.cshtml視圖。確保此視圖存在於此位置。在你的照片中，你似乎省略了Home目錄 - ~/Areas/Administration/Views/Index.cshtml。
