在我的项目中遇到多个同名控制器的问题 [英] Having issue with multiple controllers of the same name in my project

问题描述

我的 ASP.NET MVC 3 项目遇到以下错误:

I am running into the following error with my ASP.NET MVC 3 project:

找到多个匹配的类型名为家"的控制器.这个可以如果服务于此的路线发生request ('Home/{action}/{id}') 确实不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，请注册此通过调用重载来路由'MapRoute' 方法需要一个命名空间"参数.

Multiple types were found that match the controller named 'Home'. This can happen if the route that services this request ('Home/{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.

对家"的请求已找到以下匹配控制器:MyCompany.MyProject.WebMvc.Controllers.HomeControllerMyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController

The request for 'Home' has found the following matching controllers: MyCompany.MyProject.WebMvc.Controllers.HomeController MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController

我的默认控制器文件夹中有一个 HomeController，类名为 MyCompany.MyProject.WebMvc.Controllers.HomeController.

I have a HomeController in my default controller folder, with a class name of MyCompany.MyProject.WebMvc.Controllers.HomeController.

在我的 global.asax 中，我的 RegisterRoutes 方法如下所示:

My RegisterRoutes method, in my global.asax, looks like:

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

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

然后我有一个名为 Company 的区域，在该区域的默认控制器文件夹中有一个 HomeController，类名为 MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController.

I then have an area called Company, with a HomeController in the default controller folder for the area, with a class name of MyCompany.MyProject.WebMvc.Areas.Company.Controllers.HomeController.

CompanyAreaRegistration 文件中的 RegisterArea 方法如下所示:

The RegisterArea method in the CompanyAreaRegistration file looks like:

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

这都是导致我在本文开头强调的错误的原因.我正在努力尝试从其他各种帖子中拼凑出一个解决方案，运气不佳.

This is all leading the error I highlighted at the beginning of this post. I am struggling trying to piece together a solution from various other posts, with NO LUCK.

是否可以在默认控制器文件夹中有一个 HomeController，然后在每个区域中有一个?如果是这样，我是否需要(假设我这样做)更改我的配置文件才能使其正常工作?

Is it possible to have a HomeController in the default controllers folder and then one in EACH area? If so, do I need to make (assuming I do) changes to my configuration file to make this work?

任何帮助将不胜感激！

推荐答案

该错误消息包含推荐的解决方案:如果是这种情况，请通过调用采用命名空间"的MapRoute"方法的重载来注册此路由' 参数."

The error message contains the recommended solution: "If this is the case, register this route by calling an overload of the 'MapRoute' method that takes a 'namespaces' parameter."

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

这将使 http://server/ 转到您的 HomeController 的 Index 操作，我认为这就是您想要的.http://server/company/home 会去Company区域的HomeController的Index动作，在区域注册中定义.

This will make http://server/ go to your HomeController's Index action which is, I think, what you want. http://server/company/home will go to the Company area's HomeController's Index action, as defined in the area registration.
