反射获取所有视图

Posted 2021-01-02 guxingy

原地址：忘了

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());
        }

View Code
