不同区域的相同控制器名称

Question

在带有区域的 ASP.NET MVC 3 应用程序中（参见下面的架构）。根目录下的“Controllers”目录已被删除。

当我这样做时：

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

我收到此错误： 找到了与名为“Home”的控制器匹配的多种类型。 如果服务此请求的路由 ('{controller}/{action}/{id}') 没有指定命名空间来搜索与请求匹配的控制器。 如果是这种情况，请通过调用“MapRoute”的重载来注册此路由 采用“命名空间”参数的方法。 'Home' 的请求找到了以下匹配的控制器： MyProject.Areas.Administration.Controllers.HomeController MyProject.Areas.BackEnd.Controllers.HomeController MyProject.Areas.FrontEnd.Controllers.HomeController

当我这样做时：

    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 tis 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

更新1 要开始使用区域中的特定控制器，我尝试了这个：

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

尝试以下方法：

~/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" }
    );
}

现在当您请求/Administration/Home/Index 时，HomeController 在Administration 区域中的Index 操作将被调用，它将查找~/Areas/Administration/Views/Home/Index.cshtml 视图。确保此视图出现在此位置。在您的图片中，您似乎省略了 Home 目录 - ~/Areas/Administration/Views/Index.cshtml。
