不同区域中的相同控制器名称

Question

在具有区域的ASP.NET MVC 3应用程序中（请参阅下面的架构）。根目录下的“控制器”目录已被删除。

当我这样做：

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

我得到这个错误： 多种类型的发现命名为“家”的控制器匹配。 如果为该请求提供服务的路由（'{controller}/{action}/{id}'） 未指定命名空间来搜索与该请求匹配的控制器，则会发生这种情况。 如果是这种情况，请通过调用带有'namespaces'参数的'MapRoute' 方法的重载来注册此路由。 为 '家' 的请求已发现下列匹配控制器： MyProject.Areas.Administration.Controllers.HomeController MyProject.Areas.BackEnd.Controllers.HomeController MyProject.Areas.FrontEnd.Controllers.HomeController

当我这样做：

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" } 
    ); 

我得到那朵错误：

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 要开始在区域特定的控制器，我尝试这样做：

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

尝试以下操作：

~/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" } 
    ); 
} 

现在，当你要求/Administration/Home/Index的HomeController在Administration面积Index动作将被调用，它会寻找~/Areas/Administration/Views/Home/Index.cshtml视图。确保此视图存在于此位置。在你的照片中，你似乎省略了Home目录 - ~/Areas/Administration/Views/Index.cshtml。
