//MVC HTML辅助类常用方法记录
（1）@Html.DisplayNameFor(model => model.Title)是显示列名，
（2）@Html.DisplayFor(modelItem => item.Title)是显示列的内容
（3）@Html.ActionLink("Create New", "Create")是超链接，跳转到model中的create页面，引用的是controller中create方法；
（4）@Html.ActionLink("Edit", "Edit", new { id=item.ID })编辑页面；
（5）@using (Html.BeginForm()) { @Html.ValidationSummary(true)}用于客户端验证，其Html.BeginForm()表示在本页显示
（6）<div class="editor-label">
@Html.LabelFor(model => model.Time)标签
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Time)编辑框
@Html.ValidationMessageFor(model => model.Time)验证合法性错误显示
</div>
