仅仅作为简单的记录，不多说直接上代码（仅测试使用）：

        private void Test()        {             Regex ConnoteA = new Regex("^[a-zA-Z]\\d{8}$");            Regex ConnoteAA = new Regex("^[a-zA-Z]{2}\\d{7,10}$");            Regex ConnoteAAA = new Regex("^[a-zA-Z]{3}\\d{5,9}$");            Regex ConnoteAAAA = new Regex("^[a-zA-Z]{4}[a-zA-Z0-9]{8}$");            string haha = "w11111111";            string xixi = "ww1111111";            string hehe = "w111111111";            string lala = "W11111111";            string longlongstring = "w11111111222q33333333555555ee1234567890yyy111111111yyy000000AK123456Me123456tttt12345678";            bool result = ConnoteA.IsMatch(haha);            result = ConnoteA.IsMatch(xixi);            result = ConnoteA.IsMatch(hehe);            result = ConnoteA.IsMatch(lala);            foreach (Match mch in ConnoteA.Matches(longlongstring))            {                string x = mch.Value.Trim();            }            foreach (Match mch in Regex.Matches(longlongstring, "([a-zA-Z]\\d{8})|([a-zA-Z]{2}\\d{7,10})|([a-zA-Z]{3}\\d{5,9})|([a-zA-Z]{4}[a-zA-Z0-9]{8})|((AK|AL|BU|CR|EL|HF|HU|SW|SY|WU|ME)\\d{6})|([a-zA-Z]{4}\\d{8}[A-Za-z0-9]{3}\\d{4})"))            {                string x = mch.Value.Trim();            }        }
