[解决办法]

            StreamReader reader = new StreamReader("c:\\temp\\1.txt",Encoding.Default);
            string source = reader.ReadToEnd();
            Regex reg = new Regex(@"(?is)<tr class=""dataBack[\d]+"">[\s]+<td>([^<>]+)</td>[\s]+<td>([^<>]+)</td>[\s]+<td>([^<>]+)</td>[\s]+</tr>");
            MatchCollection mc = reg.Matches(source);
            foreach (Match m in mc)
            {                MessageBox.Show(m.Groups[1].Value+":"+m.Groups[2].Value+":"+m.Groups[3].Value);
            }
