在 Razor 页面中将文本显示为 html

Question

我刚刚开始使用 Blazor 和 Razor 页面。它比我正在构建的旧的纯 html 页面要好得多。但是我在将我构建的 html 字符串转换为实际 HTML 时遇到问题。现在，如果我复制并粘贴我的字符串并将其保存为 html 页面，这将有效。它显示为html没问题。但是，当我尝试让我的 Razor 页面显示它时，它显示为纯文本。甚至尝试技巧：

<div>
    @(new HtmlString(htmlString))
</div>

显示纯文本。这会很痛苦，因为它有点长，但这是我要转换的字符串：

"<pre><br><b>STATION INFO</b><br><br>            Extension: 34263                        Lock Messages? n        BCC: 0 <br>                 Type: 9630                         Security Code: 12345     TN: 1<br>                 Port: S17746                     Coverage Path 1: 132      COR: 44<br>                 Name: Lastname, Firstname                  Coverage Path 2:          COS: 1<br><br><b>STATION OPTIONS</b><br>                                                       Time of Day Lock Table: <br>                 Loss Group: 19                  Personalized Ringing Pattern: 1<br>                                                             Message Lamp Ext: 34263<br>               Speakerphone: 2-way                        Mute Button Enabled? y<br>           Display Language: english                         Expansion Module? <br>    Survivable GK Node Name: <br>             Survivable COR: internal                       Media Complex Ext: <br>      Survivable Trunk Dest?

它是由我的返回字符串的方法构建的。为了好玩，这是我的方法：

当我查看帧源时，我看到的是：

对不起，这太长了..但是有人可以帮我吗？

谢谢！

Answer 1

哇，好吧..偶然发现了答案：

<div>
    @((MarkupString)htmlString)
</div>

代替：

<div>
    @(new HtmlString(htmlString))
</div>
