更新功能在c＃中无法正常工作，无法更新到sql server数据库

Question

您好我正在编写代码来更新数据库，但我面临一些问题，希望您可以指导我

所以我想通过我的mvc应用程序更新我数据库中的数据

以下控制器代码正常工作： -

[HttpGet]
[ActionName("Edit")]
public ActionResult  Edit_Get(int id)
{
    DealMasterBLL dealMasterBLL = new DealMasterBLL();
    DealMasterInfo dealMasterInfo = dealMasterBLL.DealMasterInfo.Single(did => did.DealAutoID == Convert.ToString(id));
    return View(dealMasterInfo);
}

[HttpPost]
[ActionName("Edit")]
public ActionResult Edit_Post(DealMasterInfo dealMasterInfo)
{
    if (ModelState.IsValid)
    {
        DealMasterBLL dealMasterBLL = new DealMasterBLL();
       // dealMasterInfo = dealMasterBLL.DealMasterInfo.Single(did => did.DealAutoID ==id);
       // UpdateModel(dealMasterInfo);
        dealMasterBLL.EditDealMaster(dealMasterInfo);
        return RedirectToAction("Index");
    }
    return View();
}

但是当我在post方法中进行更改时

以下更改： -

[HttpGet]
[ActionName("Edit")]
public ActionResult  Edit_Get(int id)
{
    DealMasterBLL dealMasterBLL = new DealMasterBLL();
    DealMasterInfo dealMasterInfo = dealMasterBLL.DealMasterInfo.Single(did => did.DealAutoID == Convert.ToString(id));
    return View(dealMasterInfo);
}

[HttpPost]
[ActionName("Edit")]
public ActionResult Edit_Post(int id)
{
    DealMasterBLL dealMasterBLL = new DealMasterBLL();
    DealMasterInfo dealMasterInfo = dealMasterBLL.DealMasterInfo.Single(did => did.DealAutoID ==Convert.ToString(id));
    UpdateModel(dealMasterInfo);
    if (ModelState.IsValid)
    {

        dealMasterBLL.EditDealMaster(dealMasterInfo);
        return RedirectToAction("Index");
    }
    return View();
}

代码不起作用  我试过调试，但它正确地通过所有路径没有任何错误

我正在添加以下所有其他必需代码，请回复
