任意字符串返回ASCII码

        public static string Encode3(string data)
        {
            string Pwd = "";
            byte[] bytes = System.Text.Encoding.ASCII.GetBytes(data);
            for (int i = 0; i < bytes.Length; i++)
            {
                //Console.WriteLine(bytes[i].ToString());
                Pwd += bytes[i].ToString();
            }
