Answer 1

使用HttpUtility.HtmlDecode进行此类操作......

Answer 2

见MSDN article on HtmlDecode。您可以使用System.Web.HttpUtility.HtmlDecode()将这些转换为原始的HTML等效字符。

var html = "<img alt=\"\" src=\"http://win-thgn9fd7gfo:37996/Style Library/UWW/images/logo01.gif\" style=\"BORDER: 0px solid; \">";

html = HttpUtility.HtmlEncode(html);
// html now = "&lt;img alt=&quot;&quot; src=&quot;http://win-thgn9fd7gfo:37996/Style Library/UWW/images/logo01.gif&quot; style=&quot;BORDER: 0px solid; &quot;&gt;"

var html = HttpUtility.HtmlDecode(html);
// html is now back to its original value.
