asp.net-mvc-4 - 创建简单控制器 MVC 时出错

Question

我Default1在 ASP.NET MVC4 VS 2012 中创建一个简单的空控制器，但是当我运行它时，它会出错。

我的控制器如下：

public class Default1Controller : Controller
    {
        //
        // GET: /Default1/

        public ActionResult Index()
        {
            return View();
        }

     }

抛出以下错误：

[HttpException]: The controller for path '/Default1' was not found or does not     implement IController.
   at System.Web.Mvc.DefaultControllerFactory.GetControllerInstance(RequestContext                 requestContext, Type controllerType)
   at System.Web.Mvc.DefaultControllerFactory.CreateController(RequestContext requestContext, String controllerName)
   at System.Web.Mvc.MvcHandler.ProcessRequestInit(HttpContextBase httpContext,IController& controller, IControllerFactory& factory)
   at System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContextBase httpContext,AsyncCallback callback, Object state)
   at System.Web.Mvc.MvcHandler.BeginProcessRequest(HttpContext httpContext,AsyncCallback callback, Object state)
   at System.Web.Mvc.MvcHandler.System.Web.IHttpAsyncHandler.BeginProcessRequest(HttpContext context, AsyncCallback cb, Object extraData)
   at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionSep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

路由配置：

public class RouteConfig
    {
    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 }
        );
    }
}

实际上，我在此事件之前一直在创建控制器，但是我现在创建的某些控制器无法访问。

  routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Default1", action = "Index", id = UrlParameter.Optional }
            );
