asp.net - 发现了多种与名为 'Home'的 Controller 匹配的类型。 (两个区域，相同的 Controller 名称)

Question

这可能对许多人来说都是重复的，但是其中明显的答案并不能解决我的问题。

我得到:

Multiple types were found that match the controller named 'Home'. This can happen if the route that services this request ('{controller}/{action}/{id}') does not specify namespaces to search for a controller that matches the request. If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter.

The request for 'Home' has found the following matching controllers:
App.Web.Controllers.HomeController
App.Web.Areas.Mobile.Controllers.HomeController

我在Global.ascx.cs中为我的HomeController设置了默认 namespace :

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

(验证App.Web.Controllers.HomeController不是错字)。

并且还在MobileAreaRegistration中注册了Mobile的HomeController:

public override void RegisterArea(AreaRegistrationContext context) {
    context.MapRoute(
        "Mobile_default",
        "Mobile/{controller}/{action}/{id}",
        new { controller = "Home", action = "Index", id = UrlParameter.Optional }
    );
}

因此，为什么仍然看到错误消息？我已经盖好/打扫好了，然后又跑了。结果还是一样。

这是我注册路线的方式:

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();

    RegisterGlobalFilters(GlobalFilters.Filters);
    RegisterRoutes(RouteTable.Routes);
}

出于明显原因，请在您的Global.asax路由注册中替换:

new string[] { "App.Web.Controllers.HomeController" } 

和:

new string[] { "App.Web.Controllers" } 

那是您应在此处使用的 namespace 约束，而不是特定的类型。
