C#实现注册码的方法

// 取得设备硬盘的卷标号public static string GetDiskVolumeSerialNumber(){ ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid="d:""); disk.Get(); return disk.GetPropertyValue("VolumeSerialNumber").ToString();}//获得CPU的序列号public static string getCpu(){ string strCpu = null; ManagementClass myCpu = new ManagementClass("win32_Processor"); ManagementObjectCollection myCpuConnection = myCpu.GetInstances(); foreach (ManagementObject myObject in myCpuConnection) {  strCpu = myObject.Properties["Processorid"].Value.ToString();  break; } return strCpu;}//生成机器码public static string getMNum(){ string strNum = getCpu() + GetDiskVolumeSerialNumber();//获得24位Cpu和硬盘序列号 string strMNum = strNum.Substring(0, 24);//从生成的字符串中取出前24个字符做为机器码 return strMNum;}public static int[] intCode = new int[127];//存储密钥public static int[] intNumber = new int[25];//存机器码的Ascii值public static char[] Charcode = new char[25];//存储机器码字public static void setIntCode()//给数组赋值小于10的数{ for (int i = 1; i < intCode.Length; i++) {  intCode[i] = i % 9; }}

//生成注册码  public static string getRNum(){ setIntCode();//初始化127位数组 for (int i = 1; i < Charcode.Length; i++)//把机器码存入数组中 {  Charcode[i] = Convert.ToChar(getMNum().Substring(i - 1, 1)); } for (int j = 1; j < intNumber.Length; j++)//把字符的ASCII值存入一个整数组中。 {  intNumber[j] = intCode[Convert.ToInt32(Charcode[j])] + Convert.ToInt32(Charcode[j]); } string strAsciiName = "";//用于存储注册码 for (int j = 1; j < intNumber.Length; j++) {  if (intNumber[j] >= 48 && intNumber[j] <= 57)//判断字符ASCII值是否0－9之间  {   strAsciiName += Convert.ToChar(intNumber[j]).ToString();  }  else if (intNumber[j] >= 65 && intNumber[j] <= 90)//判断字符ASCII值是否A－Z之间  {   strAsciiName += Convert.ToChar(intNumber[j]).ToString();  }  else if (intNumber[j] >= 97 && intNumber[j] <= 122)//判断字符ASCII值是否a－z之间  {   strAsciiName += Convert.ToChar(intNumber[j]).ToString();  }  else//判断字符ASCII值不在以上范围内  {   if (intNumber[j] > 122)//判断字符ASCII值是否大于z   {    strAsciiName += Convert.ToChar(intNumber[j] - 10).ToString();   }   else   {    strAsciiName += Convert.ToChar(intNumber[j] - 9).ToString();   }  } } return strAsciiName;}
