Question

This should be a fairly simple question, all I want to do is use @Html.LabelFor within a razor view. One of my labels is different, it has an <a> tag in it. the problem is when I use LabelFor, it encodes the html as & lt;. I've tried a lot of different approaches to making this happen but none of them are working. Here's the code.

@Html.LabelFor(model => model.Question, new { @for = "Question" })

what should get outputted:

<label for="question"><a href=\"mailto:support@testdomain.com">support@testdomain.com</a></label>

what does get outputted:

&lt;label for="question"&gt;&lt;a href=\"mailto:support@testdomain.com"&gt;support@testdomain.com&lt;/a&gt;</label>

(my < have been replaced with & lt ; without the spaces, thus the code shows on the page instead of rendering as a link)

how can I make it output what it should?

note, model.Question is set to <a href="mailto:support@testdomain.com">support@testdomain.com</a>

为什么您希望标签包含完整的HTML？我认为这是存储电子邮件地址的更好方法，在您的视图中，您可以这样做：

 <a href="mailto:@Model.Email">@Model.Email</a>

获得预期结果。

修改

IMO通过对标签中的内容进行编码只会使您的工作变得更加复杂，因为标签并不意味着保留格式化的HTML或功能或类似的内容，而只是显示标题。用法示例：

型号代码：

[Display(Name = "Email address")] public string EmailAddress { get; set; }

在视图中：

@Html.LabelFor(model => model.EmailAddress): @Html.DisplayFor(model => model.EmailAddress)  @Html.DisplayNameFor(model => model.EmailAddress): @Html.DisplayFor(model => model.EmailAddress)

然后可以以任何方式组合：

[Display(Name = "Send Email")] public string EmailAddress { get; set; }

和

@Html.LabelFor(model => model.EmailAddress): <a href="mailto:@Model.EmailAddress">@Model.Email</a>

在运行时将是：

发送电子邮件： abc@server.com

你正在与Razor系统作斗争，因为它默认编码。这就是使用Razor的美妙之处。包括Label在内的许多标记类最终都会通过调用TagBuilderExtensions.ToMvcHtmlString

来呈现自己

internal static class TagBuilderExtensions
  {
    internal static MvcHtmlString ToMvcHtmlString(this TagBuilder tagBuilder, TagRenderMode renderMode)
    {
      return new MvcHtmlString(tagBuilder.ToString(renderMode));
    }
  }

MvcHtmlString表示不应再次编码的HTML编码字符串。因此，您无法通过LabelFor执行您要执行的操作。 Razor实际上是特别确保你不能。

但是因为你的麦芽酒：不管怎么说你真的不是标签：

@Html.Raw(Server.HtmlDecode(Model.MyField)

@ Html.LabelFor与<a> tag inside it
