本文介绍了解决ASP.NET MVC中控制器命名冲突的问题。当在不同命名空间下使用相同名称的控制器时，会导致运行时报错。文章提供了通过配置路由来区分不同命名空间下的控制器的方法。

当项目下：Controller/HomeController.cs时，

人在创建一个域Test,之后在建一个同名的HomeController: Areas/Test/Controller/HomeController.cs

运行报错：

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:
Web.Areas.Test.Controllers.HomeController
Web.Controllers.HomeController

解决办法：

/Areas/Test/TestAreaRegistration.cs

context.MapRoute( "Test_default", "Test/{controller}/{action}/{id}/", new { controller = "Home", action = "Index", id = UrlParameter.Optional }, new string[] { "Web.Areas.Test.Controllers"} );

/Global.asax

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