自己存档：asp.net mvc 从filterContent得到controller和action

//filterContext.RouteData.GetRequiredString("controller") + "/" + filterContext.RouteData.GetRequiredString("action");
                //filterContext.HttpContext.Response.Redirect("http://" + filterContext.HttpContext.Request.Url.Host + ":" + filterContext.HttpContext.Request.Url.Port.ToString() + "/" + retUrl);
                //filterContext.Result = new EmptyResult();
