推荐答案

您想要做的是不常见的。如果你写更多关于你想要什么，我们可以帮助更好。下面是你想要做什么。视图是由System.Web.Mvc.Html.Action调用。也就是说，如果在$ C $下面c是为一些有益的，只能在控制器中使用。在这个例子中我在SomeController调用动作关于控制器家用你要创建的扩展。

What you want to do is not common. If you write more about what you want exactly, we can help better. Below is what you're trying to do. A view is invoked by System.Web.Mvc.Html.Action. That is, if the code below is useful for something, can only be used in a controller. In the example I'm in the SomeController calling the action "About" the controller "Home" using the extension you want to create.

该扩展code：

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Mvc.Html; using System.Web.Routing; namespace StackOverflow.Controllers { public static class ControllersExtensions { public static ActionResult Index(this HomeController controller, string ViewName) { string controllerName = controller.GetType().Name.Replace("Controller", ""); RouteValueDictionary route = new RouteValueDictionary(new { action = ViewName, controller = controllerName }); RedirectToRouteResult ret = new RedirectToRouteResult(route); return ret; } } }

该SomeController：

The SomeController:

namespace StackOverflow.Controllers { public class SomeController : Controller { // // GET: /Some/ public ActionResult Index() { HomeController home = new HomeController(); return home.Index("About"); } } }

Home控制器：

The Home Controller:

public class HomeController : Controller { public ActionResult Index() { ViewBag.Message = "Modify this template to jump-start your ASP.NET MVC application."; return View(); } public ActionResult About() { ViewBag.Message = "Your app description page."; return View(); } public ActionResult Contact() { ViewBag.Message = "Your contact page."; return View(); } }
