注册码生成代码如下



 m_machineCode= GetMachineCode("RDH");

相关函数为

        public string GetMachineCode(string seriesNum)
        {
            string s = this.GetDeviceID() + seriesNum;
            MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider();
            string src = BitConverter.ToString((Encoding.Default.GetBytes(s))).Replace("-", "");
            return this.GetCode(src, 3);
        }

 

      public string GetDeviceID()
        {
            byte[] outputBuffer = new byte[0x100];
            int length = outputBuffer.Length;
            int bytesReturned = 0;
            if (!KernelIoControl(IOCTL_HAL_GET_DEVICEID, IntPtr.Zero, 0, outputBuffer, length, ref bytesReturned))
            {
                return null;
            }
            int startIndex = BitConverter.ToInt32(outputBuffer, 4);
            int num4 = BitConverter.ToInt32(outputBuffer, 12);
            int num5 = BitConverter.ToInt32(outputBuffer, 0x10);
            StringBuilder builder = new StringBuilder();
            builder.Append(string.Format("{0:X8}-{1:X4}-{2:X4}-{3:X4}-", new object[] { BitConverter.ToInt32(outputBuffer, startIndex), BitConverter.ToInt16(outputBuffer, startIndex + 4), BitConverter.ToInt16(outputBuffer, startIndex + 6), BitConverter.ToInt16(outputBuffer, startIndex + 8) }));
            for (int i = num4; i < (num4 + num5); i++)
            {
                builder.Append(string.Format("{0:X2}", outputBuffer[i]));
            }
            return builder.ToString();
        }

编码生成函数为

    GetRegHead2(m_machineCode);

        public string GetRegHead2(string machineCode)
        {
            string s = machineCode;
            MD5CryptoServiceProvider provider = new MD5CryptoServiceProvider();
            string src = BitConverter.ToString((Encoding.Default.GetBytes(s))).Replace("-", "");
            return this.GetCode(src, 2);
        }

发图，贴代码，详细说明问题
