用C#通过正则表达式截取字符串中符合条件的子字符串

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();
            }
        }
