        //
        // GET: /Home/

        public ActionResult Index()
        {

            //ViewData.Model = db.T_User.ToList();
            //return View();

            //以上两条代码相当于 

            return View(db.T_User.ToList()); //括号里的db.T_User.ToList()其实就是一个Model
        }
        public ActionResult Delete(int id)
        {
            //Single:返回序列中满足指定条件的唯一元素；如果有多个这样的元素存在，则会引发异常
            T_User t_user = db.T_User.Single(t => t.Id == id);  
            return View(t_user);
