C# 如何在IControllerFactory中更改Url

我正在处理一项任务，例如，当您转到Url:/Home/Index时， 如果浏览器语言设置为英语，则应重定向到/Home\u en/Index

现在，我设法从主控制器查看索引，但Url保持不变-/Home/Index

我还在Globas.asax中添加了一行：

ControllerBuilder.Current.SetControllerFactory（新ControllerFactoryController（））

如何在Url中将其显示为/Home\u en/Index

 public IController CreateController(RequestContext requestContext, string 
      controllerName)

        Type targetType = null;
        string[] languages = HttpContext.Current.Request.UserLanguages;



        if (languages[0] == "en-US")
        {
            requestContext.RouteData.Values["controller"] = "Home_en";
            targetType = typeof(Home_enController);

        }
        else
        {
            requestContext.RouteData.Values["controller"] = "Home_pl";
            targetType = typeof(Home_plController);

        }

        IController controller = Activator.CreateInstance(targetType) as IController;

        return controller;
    }
