[解决办法]

 string pattern = @"(?is)<div\s*class=""members_text"">\s*<a\s*class=""member_name text_overflow""[^>]*?>(?<atxt>.*?)</a>\s*<span\s*class=""member_id""[^>]*?>\((?<phone>.*?)\)</span>\s*<p\s*class=""member_role""[^>]*?>(?<sex>.*?)</p>\s*</div>";
            string htmlsource = File.ReadAllText(@"C:\1.txt", Encoding.GetEncoding("GB2312"));
            foreach (Match m in Regex.Matches(htmlsource, pattern))
            {
                Console.WriteLine(m.Groups["atxt"].Value);
                Console.WriteLine(m.Groups["phone"].Value);
                Console.WriteLine(m.Groups["sex"].Value);
                Console.WriteLine("------------------------------------");
            }

[解决办法]

            string txt = File.ReadAllText("1.txt", Encoding.Default);
            var vls = Regex.Matches(txt, "(?is)<a class=\"member_name text_overflow\".*?>(.*?)</a>\\s*<span class=\"member_id\">(.*?)</span>\\s*<p class=\"member_role\">(.*?)</p>").OfType<Match>().Select(x => "名字:" + x.Groups[1].Value + " 号码:" + x.Groups[2] + " 性别:" + x.Groups[3]);
            foreach (var item in vls)
            {
                Console.WriteLine(item);
            }
            Console.Read();
