controller 的 action 加上属性 [System.ComponentModel.Description("菜单列表")]  且  返回值为 System.Web.Mvc.ActionResult 类型，就可以获取到了

[System.ComponentModel.Description("菜单")]        public ActionResult Index()        {            return View(DbContext.Menu.Where(c=>!c.IsDelete).OrderBy(c => c.Sort).ToList());        }
