            var model = new UserViewInfo();

            model.ID = 1;

            model.Name = "李春城";

            model.Age = 13;

            model.SCID = 1;

            model.Datas = list;

            ViewData.Model = model;



            ViewBag.Drop = new SelectList(model.Datas, "SchoolID", "SName");
