这是我要截取的数据源
  Regex regex3 = new Regex("<td style=\"color: Red;font-weight:bold\"/>(?<value>.*?)</td>", RegexOptions.IgnoreCase);
                Match macht3 = regex3.Match(StrHtml);
                Arr[7] = macht3.Groups[1].Value.Trim();这是我写的正则表达式
<td style="color: Red;font-weight:bold">89-71</td>这是我要截取的数据，请各位高手看看怎么截取不到数据谢谢！！！！！！！
------最佳解决方案--------------------
你的正则多了一个 /

Regex regex3 = new Regex("<td style=\"color: Red;font-weight:bold\"/>(?<value>.*?)</td>", RegexOptions.IgnoreCase);

去掉红色部分
