        [HttpPost]
        public ActionResult LeaveMessage(FormCollection fc)
        {
            bool result = false;
            UserShopMessage userShopMessage = new UserShopMessage()
            {
                UID=Net.ConvertHelper.ToInt(fc["uid"]),
                ShopsID=Net.ConvertHelper.ToInt(fc["shopsid"]),
                ProductName=fc["productName"],
                ProductImageUrl=fc["productImage"],
                PRID=Net.ConvertHelper.ToInt(fc["prid"]),
                MessageType=,
                Message=fc["message"],
                IsRead=,
                CreateTime=DateTime.Now
            };
            result = ProductList.Instance.AddLeaveMessage(userShopMessage);
            return Content(result ? "ok" : "error");
        }

            //在这里转换
            TryUpdateModel<Student>(student, collection);
            dalStudent.Add(student);
            return RedirectToAction("Index");
