My View page, it contains many dynamic controls 我知道这个问题已经被回答了十多次，但是没有一种解决方案对我有帮助。
我有一个以下ViewModel，它由QuestionBatch数据模型，listResponseTag和listQuestion数据模型的列表组成。
查看模型
public class VM_Questionaire
{
public QuestionBatch ThequestionBatch { get; set; }
public List<Question> listQuestion { get; set; }
public List<ResponseTag> listResponseTag { get; set; }
}
控制器
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult submit_Questionaire(VM_Questionaire vm_question)
{
if (ModelState.IsValid)
{
Console.Write(Newtonsoft.Json.JsonConvert.SerializeObject(vm_question));
}
return View("Index");
}

@ Html.DisplayFor（）将不会发布值。您需要使用@ Html.HiddenFor（）和@ Html.DisplayFor（）。请参阅：Html.DisplayFor not posting values to controller in ASP.NET MVC 3

如果您不传递任何类型的数据，则将数据设置为隐藏字段，然后您将在各自的控制器处接收到数据。
谢谢。
