使用RedirectToAction的自定义路由(asp.net mvc)

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult CustomRoute()
    {
        return RedirectToAction("Index");
    }
}

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            name: "CustomRoute",
            url: "custom-route",
            defaults: new { controller = "Home", action = "CustomRoute" }
        );

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