ASP.NET MVC 复制MVC项目代码到同一个项目的时候报错The request for ‘home’ has found the following matching controll

“/”应用程序中的服务器错误。

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:
ET_Fund.M.Controllers.HomeController
ET_Fund.Mv3.Controllers.HomeController

说明: 执行当前 Web 请求期间，出现未经处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。

解决方法：

 public static void RegisterRoutes(RouteCollection routes)

 {

 //routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

 //routes.MapRoute(

 // name: "Default",

 // url: "{controller}/{action}/{id}",

 // defaults: new { controller = "home", action = "Index", id = UrlParameter.Optional }

 //);

 routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

 routes.MapRoute(

 name: "Default",

 url: "{controller}/{action}/{id}",

 defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },

 namespaces: new[] { "ET_Fund.Mv3.Controllers" }  // 此处的 et_fund.mv3 为新的控制器的名词

 );

 }
