str+="wecncnc<a href=\"listww.asp?Page=1&boardid=33&t=656727&p=11&tp=%B9%AB%BF%AAICSI%B5%C4MP3%B7%BD%B0%B8%C9%E8%BC%C6\">下一頁</a>";



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



Match m = re.Match(str);

if (m.Success)

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