FormCollection的用法

FormCollection的用法：

有时候前台抛来的字段太多，在后台一个一个例举出来显得麻烦，而且还容易出错，FormCollection解决了这个烦恼

        [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=0,
                Message=fc["message"],
                IsRead=0,
                CreateTime=DateTime.Now
            };
            result = ProductList.Instance.AddLeaveMessage(userShopMessage);
            return Content(result ? "ok" : "error");
        }

[HttpPost]  
public ActionResult Create(FormCollection collection)  
{  
    try  
    {  
        if (ModelState.IsValid)  
        {  
            var student = new Student();  
            //在这里转换  
            TryUpdateModel<Student>(student, collection);  
            dalStudent.Add(student);  
            return RedirectToAction("Index");  
        }  
        else  
            return View();  
    }  
    catch  
    {  
        return View("Create");  
    }
