ASP.NET利用正则表达式提取字符串中的数字

一言不足以毕之，请LOOK代码：

            string text = " 订单5|本次付款：4783|本单结清,";
            string pat = @"(\d+)";
            Regex r = new Regex(pat, RegexOptions.IgnoreCase);
            Match m = r.Match(text);
            int matchCount = 0;
            while (m.Success)
            {
                ++matchCount;
                Group g = m.Groups[1];
                Response.Write("Match" + matchCount +"："+ g + "<br />");

                m = m.NextMatch();
            }

刚才写错了个地方，不是Length是Count：

string text = " 订单5|本次付款：4783|本单结清,";
string pat = @"\d+";
Regex r = new Regex(pat);
MatchCollection m = r.Matches(text);
for (int i = 0; i < m.Count; i++) {
    Response.Write("Match" + (i+1) +"："+ m[i].Value + "<br />");
}
