C# 生成软件注册码

今天早上，花了一个早上弄了个生成机器码和注册码的Demo，通过生成的注册码里面包含时间信息，保证了注册码在使用后的指定时间后失效

由于数学不行所以写的比较简单，ok 上代码吧

1. 产生机器码的原理很简单，基本上都是取设备信息之后加密

        /// <summary>        /// 取本机机器码        /// </summary>        public static string GetMachineCode()        {           //CPU信息           string cpuId = DeviceHelper.GetCpuID();           //磁盘信息           string diskId = DeviceHelper.GetDiskID();           //网卡信息           string MacAddress = DeviceHelper.GetMacAddress();           string m1 = GetMD5(cpuId + typeof(string).ToString());           string m2 = GetMD5(diskId + typeof(int).ToString());           string m3 = GetMD5(MacAddress+typeof(double).ToString());           string code1 = GetNum(m1, 8);           string code2 = GetNum(m2, 8);           string code3 = GetNum(m3, 8);           return code1 + code2 + code3;        }

1. 产生注册码

        /// <summary>        /// 根据机器码产生注册码        /// </summary>        /// <param name="machineCode">机器码</param>        /// <param name="overTime">到期时间</param>        /// <returns></returns>        public static string CreateRegisterCode(string machineCode,DateTime overTime)        {            int year = int.Parse(overTime.Year.ToString().Substring(2))+33;            int month = overTime.Month+21;            int day = overTime.Day+54;            int section = machineCode.Length / 4;            string reg = "";            int n = 1597;            for (int i = 0; i < section; i++)            {                int sec = int.Parse(machineCode.Substring(i*4,4));                int resu = sec + n;                if (resu >= 10000)                {                    resu = sec - 1597;                }                reg += resu ;                n = n + 1597;            }           //插入年月日信息           reg = InsertNum(reg, year, 0, 8, 4, 6, 7, 1, 3, 2, 5, 9);           reg = InsertNum(reg, month, 0, 6, 9, 7, 3, 8, 4, 1, 2, 5);           reg = InsertNum(reg, day, 0,1, 2, 5, 6,7, 3, 8,  9, 4);           return reg.ToString();        }        /// <summary>        /// 在指定数字后面插入内容        /// </summary>        /// <param name="str"></param>        /// <param name="num"></param>        /// <param name="index"></param>        /// <param name="pmc"></param>        /// <returns></returns>        static string InsertNum(string str,int num,int index,params int[] pmc)        {            int posi = str.IndexOf(pmc[index].ToString());            if (posi <= -1)                return InsertNum(str, num, index + 1, pmc);            return str.Insert(posi, num.ToString());        } 

1. 验证注册码

        /// <summary>        /// 检查注册码        /// </summary>        /// <param name="registerCode"></param>        /// <param name="overTime"></param>        /// <returns></returns>        public static bool CheckRegister( string registerCode,ref DateTime overTime)        {            try            {                string machineCode = GetMachineCode();                //提取年月日                int day = int.Parse(ExtractNum(ref registerCode, 0, 1, 2, 5, 6, 7, 3, 8, 9, 4));                int month = int.Parse(ExtractNum(ref registerCode, 0, 6, 9, 7, 3, 8, 4, 1, 2, 5));                int year = int.Parse(ExtractNum(ref registerCode, 0, 8, 4, 6, 7, 1, 3, 2, 5, 9));                day -= 54;                month -= 21;                year -= 33;                overTime = new DateTime(year, month, day);                //核对注册码                int section = machineCode.Length / 4;                int n = 1597;                string reg = "";                for (int i = 0; i < section; i++)                {                    int sec = int.Parse(machineCode.Substring(i * 4, 4));                    int resu = sec + n;                    if (resu >= 10000)                    {                        resu = sec - 1597;                    }                    reg += resu;                    n = n + 1597;                }                return registerCode == reg;            }            catch {                return false;            }        }        /// <summary>        /// 提取数字        /// </summary>        /// <param name="str"></param>        /// <param name="index"></param>        /// <param name="pmc"></param>        /// <returns></returns>        static string ExtractNum(ref string str, int index, params int[] pmc)        {            int posi = str.IndexOf(pmc[index].ToString());            if (posi <= -1)                return ExtractNum(ref str, index + 1, pmc);            string resu = str.Substring(posi - 2, 2);            str = str.Remove(posi - 2, 2);            return resu;        }

1. 调用实例

           //取机器码           string mCode = RegInfo.GetMachineCode();           //产生注册码           string regCode = RegInfo.CreateRegisterCode(mCode, DateTime.Now);           DateTime time = DateTime.Now;           //验证注册码           bool resu = RegInfo.CheckRegister(regCode+"1", ref time);
