Question

我只是在阅读这个帖子：MVC How to pass a list of objects with List Items POST action method

控制器 - 获取方法

public ActionResult CheckStep1(int id)
{
  var vm = new List<CheckStep>();
  return View(vm);
}

但我的控制器总是接收参数为null

[HttpPost]
public ActionResult CheckStep1(ICollection<CheckStep> model)
{
  //TODO - here models is null
  return RedirectToAction("Index");
}

视图

@using (Html.BeginForm(Html.BeginForm("CheckStep1", "MyController", FormMethod.Post)))
{
  @Html.ValidationSummary(true)
  @for (var i = 0; i < Model.CheckStep.Count; i++)
  {
    <tr>
      <td>
        @Html.EditorFor(x => x.CheckStep[i].Id)
      </td>
      <td>
        @Html.EditorFor(x => x.CheckStep[i].name)
      </td>
    </tr>
  }  
})

我检查了我的fiddler并且所有参数都在URL中，但由于某种原因，控制器总是获得空值
