软件添加注册码

//步骤一: 获得CUP序列号和硬盘序列号的实现代码如下:   
  
  
//取CPU序号   
        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=\"d:\"");      
            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             
        private void button1_Click(object sender, EventArgs e)      
        {      
            label2.Text = 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] = label2.Text.Substring(i, 1);      
            } label2.Text = "";      
            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       
            {      
                label2.Text += strid[rdid.Next(0, 24)];      
            }      
        }      
  
  
步骤三: 使用机器码生成软件注册码, 代码如下:   
  
  
        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);      
            }      
        }       
          
        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            
        private void button2_Click(object sender, EventArgs e)      
        {      
            if (label2.Text != "")      
            {                //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(label2.Text.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 = null;//用于存储机器码              
                for (int j = 1; j < intNumber.Length; j++)      
                {      
                    //MessageBox.Show((Convert.ToChar(intNumber[j])).ToString());       
                    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();      
                        }      
                    }      
                    label3.Text = strAsciiName;//得到注册码          
                }      
            }      
            else     
            {      
                MessageBox.Show("请选生成机器码", "注册提示");      
            }      
        }      
  
  
  
步骤四: 用户输入注册码注册软件, 演示代码如下:   
  
  
        private void btnRegist_Click(object sender, EventArgs e)      
        {      
            if (label3.Text != "")      
            {      
                if (textBox1.Text.TrimEnd().Equals(label3.Text.TrimEnd()))      
                {      
                    Microsoft.Win32.RegistryKey retkey = Microsoft.Win32.Registry.CurrentUser.OpenSubKey("software", true).CreateSubKey("ZHY").CreateSubKey("ZHY.INI").CreateSubKey(textBox1.Text.TrimEnd());      
                    retkey.SetValue("UserName", "MySoft");      
                    MessageBox.Show("注册成功");      
                }      
                else { MessageBox.Show("注册码输入错误"); }      
            }      
            else     
            {      
                MessageBox.Show("请生成注册码", "注册提示");      
            }      
        }
