Answer 1

获取td内容？
            string str = File.ReadAllText(@"E:\1.txt", Encoding.GetEncoding("gb2312"));
            Regex reg = new Regex(@"(?is)<table[^>]*?class=""ft12r""[^>]*?>(?:.*?<td[^>]*?>(?:\s*<a[^>]*?>\s*)?(.*?)(?:\s*</a>\s*)?</td>)+.*?</table>");
            foreach (Match m in reg.Matches(str))
                foreach (Capture c in m.Groups[1].Captures)
                    Console.WriteLine(c.Value);
