[解决办法]
格式固定吗，楼主应该是要同时取多个吧，这样试下

string yourStr = ...........;
MatchCollection mc = Regex.Matches(yourStr, @ " <tr[^> ]*?> [\s\S]*? <a\s+href=([ " " ']?)(? <url> [^ " " '\s]*)\1?[^> ]*?> (? <text> [^ <]*?) </a> \s* <span[^> ]*?> \((? <time> [^ <\)]*?)\) </span> </td> \s* </tr> ", RegexOptions.IgnoreCase);
foreach (Match m in mc)
{
richTextBox2.Text += m.Groups[ "url "].Value + "\n ";
richTextBox2.Text += m.Groups[ "text "].Value + "\n ";
richTextBox2.Text += m.Groups[ "time "].Value + "\n ";
}
