提交时未通过MVC3 Razor复选框值

Question

我有一个表单，在列表中有几个复选框项。我为这个列表准备了一个编辑器。它们在屏幕上显示得很好。但在提交时，选中的项目不会在模型中提交...

型号：

public class ContactUsersModel : BaseModel
{
     public IList<FilterCheckModel> PreviousVisitors { get; set; }
}

public class FilterCheckModel : BaseModel
{
    public string Name { get; set; }
    public string Value { get; set; }
    public bool IsChecked { get; set; }        
}

控制器：

IList<FilterCheckModel> prevVisitList = new List<FilterCheckModel>();
prevVisitList.Insert(0, new FilterCheckModel() { Name = "All previous visitors", Value = "0" });
prevVisitList.Insert(1, new FilterCheckModel() { Name = "Not visited in last month", Value = "1" });
prevVisitList.Insert(2, new FilterCheckModel() { Name = "Not visited for 1-3 months", Value = "2" });
prevVisitList.Insert(3, new FilterCheckModel() { Name = "Not visited for 3-6 months", Value = "3" });
prevVisitList.Insert(4, new FilterCheckModel() { Name = "Not visited for over 6 months", Value = "4" });
model.PreviousVisitors = prevVisitList;

html：

 <table>
       <tr>
         <th>
             Previous visitors:
         </th>
       </tr>
       @for (int i = 1; i < Model.PreviousVisitors.Count; i++)
       {
           @Html.EditorFor(model => model.PreviousVisitors[i], "FilterCheck", new { Index = i + 1})
       }
  </table>

编辑：

<tr>
    <td>
        @Model.Name
    </td>
    <td>
        @Html.CheckBoxFor(x => x.IsChecked)
        @Html.HiddenFor(x => x.Value)
    </td>
</tr>

Answer 1

找到了！

原因是在我的循环中，i= 1开始。这会因为某种原因导致问题。索引需要从0开始...

  @for (int i = 1; i < Model.PreviousVisitors.Count; i++)

所以我把这个改成了

  @for (int i = 0; i < Model.PreviousVisitors.Count; i++)

它成功了！
