C# 给自己写的软件，加注册码功能。

　　为自己写的程序加一个注册功能吧。生成的机器号是根据CPU和硬盘号来的，根据自己的需求改成是否是随机生成。

　　代码直接粘贴到新建类覆盖原代码就能直接用了。

namespace RegisterClass

{

    class RegisterClass

    {

        //步骤一: 获得CUP序列号和硬盘序列号的实现代码如下:

        //获得CPU的序列号



        bool Stupids = true;

        bool Cat = false;

       public 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;

        }

 

        //取得设备硬盘的卷标号



       public string GetDiskVolumeSerialNumber()

        {

            ManagementClass mc = 

                 new ManagementClass("Win32_NetworkAdapterConfiguration");

            ManagementObject disk = 

                 new ManagementObject("win32_logicaldisk.deviceid=\"c:\"");

            disk.Get();

            return disk.GetPropertyValue("VolumeSerialNumber").ToString();

        }

 

 

        //步骤二: 收集硬件信息生成机器码, 代码如下: 

        //生成机器码



       public string CreateCode()

        {

            string temp = getCpu() + GetDiskVolumeSerialNumber();//获得24位Cpu和硬盘序列号

            string[] strid = new string[24];//

            for (int i = 0; i < 24; i++)//把字符赋给数组

            {

                strid[i] = temp.Substring(i, 1);

            }

            temp = "";

            //Random rdid = new Random();

            for (int i = 0; i < 24; i++)//从数组随机抽取24个字符组成新的字符生成机器三

            {

                //temp += strid[rdid.Next(0, 24)];

                temp += strid[i+3>=24?0:i+3];

            }

            return GetMd5(temp);

        }



        //步骤三: 使用机器码生成软件注册码, 代码如下:

        //使用机器码生成注册码

        public int[] intCode = new int[127];//用于存密钥



        public void setIntCode()//给数组赋值个小于10的随机数

        {

            //Random ra = new Random();

            //for (int i = 1; i < intCode.Length;i++ )

            //{

            //    intCode[i] = ra.Next(0, 9);

            //}

            for (int i = 1; i < intCode.Length; i++)

            {

                intCode[i] = i + 3 > 9 ? 0 : i + 3;

            }

        }

        public int[] intNumber = new int[25];//用于存机器码的Ascii值

        public char[] Charcode = new char[25];//存储机器码字

    

        //生成注册码

        public string GetCode(string code)

        {

            if (code != "")

            {

                //把机器码存入数组中

                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(code.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。

                  {
