上面有BUG,把https和ftp都变成了http,下面做了修正:

Regex UrlRegex = new Regex(@"((http|ftp|https):\/\/(([\w.]+\/?)[\S]*))");//查找带有http|ftp|https的URL
Text = UrlRegex.Replace(Text, "<a href=\"$1\" target=\"_blank\" style=\"color: #004299\">$1</a>");


UrlRegex = new Regex(@"((?<!(http|ftp|https):\/\/)((www.)([\w.]+\/?)\S*))");//查找不带有http|ftp|https,但以www.开头的URL


Text = UrlRegex.Replace(Text, "<a href=\"http://$1\" target=\"_blank\" style=\"color: #004299\">$1</a>");Regex EmailRegex = new Regex(@"([a-zA-Z_0-9.-]+\@[a-zA-Z_0-9.-]+\.\w+)", RegexOptions.IgnoreCase | RegexOptions.Compiled);//查找EMAIL

Text = EmailRegex.Replace(Text, "<a href=\"mailto:$1\" target=\"_blank\" style=\"color:#004299\">$1</a>");
