这是一个非常常见的问题，但我被卡住了

我有一个模型类，我想在视图中编辑它：

public class FormFillModel
{
    public int Id { get; set; }
    public string Title { get; set; }
    public string Description { get; set; }

    public string Sector { get; set; }
    public List<FormFieldModel> Fields { get; set; }
}

model.Fields属性为空

编辑：结果Html

我该怎么办？

在迭代列表时，尝试在editortemplate中使用索引访问：

@for (int i=0; i<Model.Count(); i++)
{
    <div class="editor-field">
        @Html.TextBoxFor(model => Model[i].Val)
    </div>
}

这怎么可能？您的视图的确切视图模型是什么？

附加的字段列表呈现了错误的字段名，因此它无法绑定回发帖时模型的字段属性。

但我没有使用DefaultModelBinder。有趣的是，对于HttpGet，编辑器模板正在工作。我的意思是，当我显示表单时，这是有效的。但是当我发帖时，模型对象返回的属性为空。@piedpiper我想你正在使用它-但是，我还没有把你的问题读到最后。我已经完全改写了我的答案。请再次检查。请发布为字段propertyOk的输入元素之一生成的HTML，我编辑了我的帖子。请检查。我怀疑出了什么问题，但我找不到解决方案……我知道这看起来很可笑，但FormFieldsListModel.cshtml接受与model.FieldsList.Fields类型相同的列表。

    [HttpPost]
    public ActionResult FillForm(int id, FormFillModel model)
    {
        return RedirectToAction("UserPage");
    }
