[ASP.net教程].NET编码解码(HtmlEncode与HtmlEncode)


编码代码:

System.Web.HttpUtility.HtmlEncode("<a href=\"http://hovertree.com/\">何问起</a>");

解码代码:

System.Web.HttpUtility.HtmlDecode("&lt;a href=&quot;http://hovertree.com/&quot;&gt;&#20309;&#38382;&#36215;&lt;/a&gt; "); 

效果体验:http://tool.hovertree.com/htmlcode/

本工具还可以实现Unicode解码,例如可以把以下代码解码试试:

&#60;&#97;&#32;&#104;&#114;&#101;&#102;&#61;&#34;&#104;&#116;&#116;&#112;&#58;&#47;&#47;&#104;&#111;&#118;&#101;&#114;&#116;&#114;&#101;&#101;&#46;&#99;&#111;&#109;&#47;&#34;&#62;&#20309;&#38382;&#36215;&#65292;&#25105;&#29233;&#20320;&#65292;&#23601;&#20687;&#32769;&#40736;&#29233;&#22823;&#31859;&#12290;&#60;&#47;&#97;&#62;&#32;

 

详细实现:


Default.aspx
