无法将 HTML 转换为纯文本：ASP.net

Question

我有以下从 sql server 检索到的 HTML 文本。

"<span style="color: rgb(36, 39, 41); font-family: Arial, &quot;Helvetica Neue&quot;, Helvetica, sans-serif; font-size: 15px; background-color: rgb(255, 255, 255);">So, first method looks nice and it's easy but is there is any simpler way to write the second function? Both are working well and giving a correct output.</span>" 

我想将 html 转换为纯文本并将其设置在 asp.net 中的标签上。

要做到这一点：

1. 我已从 Dataset 中的 sql server 检索到数据。

2. 设置上面检索到的标签

        <h3 id="lblqNotes" runat="server" class="text-questiondata" style="color:#1E90FF">
      </h3>
   

在后面的代码中：

  lblqNotes.InnerText = System.Net.WebUtility.HtmlDecode(values[2]);

但标签上的输出仍然是 html 代码，而不是纯文本。

感谢您的帮助。

Answer 1

您可以使用XmlDocument：

    static void Main(string[] args)
    {
        var xmlDocument = new XmlDocument();
        var html = @"<span style=""color: rgb(36, 39, 41); font - family: Arial, &quot; Helvetica Neue&quot;, Helvetica, sans - serif; font - size: 15px; background - color: rgb(255, 255, 255); "">So, first method looks nice and it's easy but is there is any simpler way to write the second function? Both are working well and giving a correct output.</span>";
        xmlDocument.LoadXml(html);

        var text = xmlDocument.InnerText;
        // So, first method looks nice and it's easy but is there is any simpler way to write the second function? Both are working well and giving a correct output.
    }

尝试此代码使用正则表达式去除 Html：output = Regex.Replace(source, "<[^>]*>", string.Empty);
