动作方法

＆＃xA;＆＃xA;

  [HttpPost ]＆＃xA; public ActionResult editSubjectSuggestions（List＆lt; SubjectSuggestionModel＆gt; models）＆＃xA; {＆＃xA; return view（“subjectSuggestion”，prsubList.getSubjectSuggestionsList（＆＃xA; Convert.ToInt32（Session [“subjectID”]。ToString（））））;＆＃xA;}＆＃xA;

使用foreach循环生成重复的id属性（无效的html）和重复的name属性，而不使用无法绑定到集合的索引器。您必须使用for循环或自定义EditorTemplate作为类型。

使用for循环

<tbody>
  @for (int i = 0; i < Model.Count; i++)
  {
    <tr>
      <td>@Html.TextBoxFor(m => m[i].subject_id, new { @readonly = "readonly" })</td>
      <td>@Html.TextBoxFor(m => m[i].suggestion_order)</td>
      <td>@Html.TextBoxFor(m => m[i].suggested_subject_id)</td>
    </tr>
  }
</tbody>

使用EditorTemplate

在/Views/Shared/EditorTemplates/SubjectSuggestionModel.cshtml

@model SubjectSuggestionModel
<tr>
  <td>@Html.TextBoxFor(m => m.subject_id, new { @readonly = "readonly" })</td>
  <td>@Html.TextBoxFor(m => m.suggestion_order)</td>
  <td>@Html.TextBoxFor(m => m.suggested_subject_id)</td>
</tr>

并在主视图中

<tbody>
  @Html.EditorFor(m => m)
</tbody>

列表模型不返回数据
