我已经在这里待过几次了，如果可能的话，我会喜欢看几双“新鲜”的眼睛。
在我的应用程序中，我有一个表单，我使用的模型包含一些原始类型和两个列表。我也在使用Kendo网格。
我的问题是，当用户提交时，模型到达正常，但两个列表中的一个返回0个元素......！ （永不为空）
到达的列表是我在Kendo Grid中创建的列表。
返回空的列表是List ProductItemlist，它是在局部视图中生成的（也尝试不使用局部视图）。
事情是，如果我这样做在控制器上：
string test = Request.Form [“ProductItemlist [0] .ProductItemId”]，
我得到了我想要的值，所以我认为问题必须在映射中。
然而，我没有发现它......
发生了什么......？在此先感谢您的帮助！

我的控制器：
[HttpPost]
public ActionResult ProcessPurchases(PurchaseRegistrationProductEditVM model)
{
Log.Instance.Info(string.Format(LogConst.CONTROLLER, "Client", "ProcessPayments", "Get"));
string test = Request.Form["ProductItemlist[0].ProductItemId"];
return RedirectToAction("Details/" + model.ClientId, "Client");
}
答案 0 :(得分：1)
经过一夜安眠后，我能够解决这个问题！ :)
最后问题出在这一行：
@ Html.HiddenFor（model =＆gt; model.ProductItemlist）
由于我已经存储了相同类型的列表，因此表单映射器使用的是第一个。而且由于你无法在隐藏字段中保存整个列表......它返回了一个用0个元素初始化的列表！
删除该行后，一切都像魅力一样开始工作！
