MVC4.0中下来列表框的，两种使用方法DropDownList

后台控制器代码

        {

            var list = new List<SchoolInfo>();

            list.Add(new SchoolInfo() { SchoolID = 1, SName = "北京大学" });

            list.Add(new SchoolInfo() { SchoolID = 2, SName = "上海大学" });

            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");

            return View();
