test.test.com/Supply/Detail_6720130_143104102.shtml

这2种格式的URL 我想用同1个正则 将6720130 取出来
有办法写吗？

[解决办法]

C# code

 string tempStr = File.ReadAllText(@"C:\Documents and Settings\Administrator\桌面\Test.txt", Encoding.GetEncoding("GB2312"));//读取txt                string pattern = @"(?<=/\D*?)\d+(?=.*?\.)";                foreach (Match m in Regex.Matches(tempStr, pattern))                {                    //循环输出                    string value = m.Value;//6720130                }
