如何解决找到与命名控制器匹配的多个类型 [英] how sloved Multiple types were found that match the controller named

问题描述

我看到了这个错误

找到了多个匹配名为Home的控制器的类型。如果为此请求提供服务的路由（'{Controller} / {action} / {id}'）未指定名称空间来搜索与请求匹配的控制器，则会发生这种情况。如果是这种情况，请通过调用带有'namespaces'参数的'MapRoute'方法的重载来注册此路由。



'Home'的请求具有找到了以下匹配的控制器：

Web.Areas.BaseAdmin.Controllers.HomeController

Web.Controllers.HomeController

iam see this error
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.BaseAdmin.Controllers.HomeController
Web.Controllers.HomeController

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.MapRoute(
              name: "baseadmin",
           url: "BaseAdmin/Home/{action}/{id}",
              defaults: new
              {
                  controller = "BaseAdmin/Home",
                  action = "Index",
                  issueId = UrlParameter.Optional,
                  projectId = UrlParameter.Optional
              }
          );
      }
  }

推荐答案

you can mention the namespace in the route config as explained below:

 routes.MapRoute(
              name: "Default",
              url: "{Controller}/{action}/{id}",
              defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional },
namespaces: Web.Controllers
          );

         routes.MapRoute(
              name: "baseadmin",
           url: "BaseAdmin/Home/{action}/{id}",
              defaults: new
              {
                  controller = "BaseAdmin/Home",
                  action = "Index",
                  issueId = UrlParameter.Optional,
                  projectId = UrlParameter.Optional
              },
           namespaces:Web.Areas.BaseAdmin.Controllers
          );
