开发软件时，当用到商业用途时，注册码与激活码就显得很重要了。现在的软件破解技术实在在强了，各种国内外大型软件都有注册机制，但同时也不断地被破解。下面发的只是一个常用版本，发出源码被破就更容易了，但我们学习的是技术。当然也为以后自己的软件不会被轻易破解。

第一步。根据卷标，CPU序列号，生成机器码  
// 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;  
            \}  
        \}

第二步。根据机器码 生成注册码  
        //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;  
        \}

第三步。检查注册状况，若没有注册，可自定义试用

/// <summary>  
        /// 检查注册  
        /// </summary>  
        private void CheckRegist()  
        \{

this.btn\_reg.Enabled = true;

RegistryKey retkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey(“software”, true).CreateSubKey(“wxk”).CreateSubKey(“wxk.INI”);  
                foreach (string strRNum in retkey.GetSubKeyNames())//判断是否注册  
                \{  
                    if (strRNum == clsTools.getRNum())  
                    \{  
                        thControl(true);  
                        return;  
                    \}  
                \}  
                thControl(false);  
                Thread th2 = new Thread(new ThreadStart(thCheckRegist2));  
                th2.Start();

\}  
        \}  
       
        /// <summary>  
        /// 验证试用次数  
        /// </summary>  
        private static void thCheckRegist2()  
        \{  
            MessageBox.Show(“您现在使用的是试用版，该软件可以免费试用3000000次！”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);  
            Int32 tLong;  
            try  
            \{  
                tLong = (Int32)Registry.GetValue(“HKEY\_LOCAL\_MACHINE\\SOFTWARE\\angel”, “UseTimes”, 0);  
                MessageBox.Show(“感谢您已使用了” + tLong + “次”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);  
            \}  
            catch  
            \{  
                Registry.SetValue(“HKEY\_LOCAL\_MACHINE\\SOFTWARE\\angel”, “UseTimes”, 0, RegistryValueKind.DWord);  
                MessageBox.Show(“欢迎新用户使用本软件”, “提示”, MessageBoxButtons.OK, MessageBoxIcon.Information);  
            \}  
            tLong = (Int32)Registry.GetValue(“HKEY\_LOCAL\_MACHINE\\SOFTWARE\\angel”, “UseTimes”, 0);  
            if (tLong < 3000000)  
            \{  
                int Times = tLong + 1;  
                Registry.SetValue(“HKEY\_LOCAL\_MACHINE\\SOFTWARE\\angel”, “UseTimes”, Times);  
            \}  
            else  
            \{  
                MessageBox.Show(“试用次数已到”, “警告”, MessageBoxButtons.OK, MessageBoxIcon.Warning);  
                Application.Exit();  
            \}  
        \}
