Question

我有一个ASP.NET MVC视图，其中包含许多类似的代码，我试图弄清楚是否有办法合并它。以下是Question1的示例，我希望在18个问题中生成相同的内容。

<div class="editor-label">
    @Html.LabelFor(model => model.Question1)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.Question1)
    @Html.ValidationMessageFor(model => model.Question1)
</div>

<div class="editor-label">
    @Html.LabelFor(model => model.Question1Type)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.Question1Type)
    @Html.ValidationMessageFor(model => model.Question1Type)
</div>

<div class="editor-label">
    @Html.LabelFor(model => model.Question1Required)
</div>
<div class="editor-field">
    @Html.EditorFor(model => model.Question1Required)
    @Html.ValidationMessageFor(model => model.Question1Required)
</div>

有没有办法循环遍历所有问题的循环或MVC中的其他一些机制来整合18个问题的代码？

Answer 1

看看这篇文章。它解释了如何从列表中绑定视图。通过对ViewModel进行一些调整，我相信它对您也很有用。

我觉得这样的事情会奏效：

@{
  var properties = new List<Func<Model, object>> 
                   { 
                       model => model.Question1, 
                       model => model.Question1Type, 
                       model => model.Question1Required
                   };
 }
 @foreach( property in properties ) {
     <div class="editor-label">
        @Html.LabelFor(property )
     </div>
     <div class="editor-field">
        @Html.EditorFor(property )
        @Html.ValidationMessageFor(property )
     </div>
 }
