在C＃中将HTML转义字符解码回普通字符串

Question

My question is simple. I searched a little online, but could not find a quick way to unescape HTML text in a string.

For example:
"< > &" should be returned to "< > &" as a string.

Is there a quick way, or do I have to write my own unescaper?

Answer 1

使用System.Web.HttpUtility.HtmlDecode或System.Net.WebUtility.HtmlDecode

var decoded = HttpUtility.HtmlDecode("< > &");

Answer 2

如果您使用的是.NET 4.5，则可以使用HttpUtility.HtmlDecode方法。

Answer 3

HttpUtility.UrlDecode("Your escaped String", System.Text.Encoding.Default);
