如何用Razor显示条件纯文本

Question

我在else块中显示(而不是显示)纯文本时遇到问题.

if (Model.CareerFields != null && ViewBag.CFCount > 0)
{
<h3>Careerfields Listing</h3>

<table>
   <tr>
      <th></th>
      <th>Careerfield Name</th>
   </tr>

   @foreach (var item in Model.CareerFields)
   {
       <tr>
       <td>
          @Html.ActionLink("Select", "Index", new { careerFieldID = item.CareerFieldId })
       </td>
       <td>
          @item.CareerFieldName
       </td>
       </tr>
   }
   </table>
}
else
{
  No Careerfields associated with @ViewBag.SelectedDivisionTitle
}

if块工作正常.文本仅在呈现时呈现.但是,else块文本在页面加载时呈现,而不是仅在其计算结果为false时呈现.

我试过用了

Hmtl.Raw("No Careerfields associated with ")
<text>No Careerfields associated with @ViewBag.SelectedDivisionTitle</text>
@:No Careerfields associated with @ViewBag.SelectedDivisionTitle

但它仍然在评估之前呈现明文.

有什么建议？

Answer 1

将您的"纯文本"放在裸<span>标记内:

else
{
  <span>No Careerfields associated with @ViewBag.SelectedDivisionTitle</span>
}

浏览器不应该使它特殊(除非你有css选择每个跨度),它将帮助剃刀感知C#的结尾并打印你的HTML.

Answer 2

最简洁、最正确的答案是：

放在@:文本前面。

（注意:后面的@）

@这仍然允许通过在变量名称前面添加 an 来在文本中嵌入变量：

@if (someCondition)
{
   @:Some text you want to see.
}
else
{
   @:Some other text, with a variable @someVariable included in the text.
}

Answer 3

以下代码对我来说非常合适:

@if (false) {
    <h3>
        Careerfields Listing
    </h3>
    <table>
        <tr>
            <th>
            </th>
            <th>
                Careerfield Name
            </th>
        </tr>
    </table>
}
else 
{ 
    @:No Careerfields associated with @ViewBag.SelectedDivisionTitle
}

您可以看到在将条件更改为true时呈现if的内容.
