一段找出URL的代码（C#）

string str="wecncnc<a href=/"list.asp?Page=1&amp;boardid=33&amp;t=656727&amp;p=11&amp;tp=%B9%AB%BF%AAICSI%B5%C4MP3%B7%BD%B0%B8%C9%E8%BC%C6/">下一页</a>";

str+="wecncnc<a href=/"listww.asp?Page=1&amp;boardid=33&amp;t=656727&amp;p=11&amp;tp=%B9%AB%BF%AAICSI%B5%C4MP3%B7%BD%B0%B8%C9%E8%BC%C6/">下一页</a>";



Regex re = new Regex(@"<a[^>]+href=""(?<url>[^""]+)""",RegexOptions.IgnoreCase);



Match m = re.Match(str);

if (m.Success)

Console.WriteLine(m.Groups["url"].Value);
