C#或js如何获取域名？

高手进。

你可以通过 url来获得IP 和 域名的 注意看下绝对路径

javascript 获取域名

<script language="javascript"> //获取域名 host = window.location.host; host2=document.domain; //获取页面完整地址 url = window.location.href; document.write("<br>host="+host) document.write("<br>host2="+host2) document.write("<br>url="+url) </script>

C#根据网址获取域名

public string GetUrlDomainName(string strHtmlPagePath) { string p = @"http://[^\.]*\.(?<domain>[^/]*)"; Regex reg = new Regex(p,RegexOptions.IgnoreCase); Match m = reg.Match(strHtmlPagePath); return m.Groups["domain"].Value; }
