我想从上面的字符串里面取出<a href='mailto:'></a>这样的字符串，当然mailto:也是可以有内容的，链接之间也是可以有内容的。
我自己写了一个简单的正则，<a href=("mailto:[^\"]+;?"|'mailto:[^\"]+;?'|"mailto:"|'mailto:')>[^</]</a>，但还是不行，希望高手来指点一下，在线等

try...

Regex reg = new Regex(@"(?is)<a[^>]*?href=(['""]?)mailto:[^'""\s>]*\1[^>]*>.*?</a>");
MatchCollection mc = reg.Matches(yourStr);
foreach (Match m in mc)
{
    richTextBox2.Text += m.Value + "\n";
}
