C# 給自己寫的軟件，加注冊碼功能。

　　為自己寫的程序加一個注冊功能吧。生成的機器號是根據CPU和硬盤號來的，根據自己的需求改成是否是隨機生成。

　　代碼直接粘貼到新建類覆蓋原代碼就能直接用了。

        //步驟一: 獲得CUP序列號和硬盤序列號的實現代碼如下:
        //獲得CPU的序列號

        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;
        }
 
        //取得設備硬盤的卷標號

       public string GetDiskVolumeSerialNumber()
        {
            ManagementClass mc = 
                 new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObject disk = 
                 new ManagementObject("win32_logicaldisk.deviceid=\"c:\"");
            disk.Get();
            return disk.GetPropertyValue("VolumeSerialNumber").ToString();
        }
 
 
        //步驟二: 收集硬件信息生成機器碼, 代碼如下: 
        //生成機器碼

       public string CreateCode()
        {
            string temp = getCpu() + GetDiskVolumeSerialNumber();//獲得24位Cpu和硬盤序列號
            string[] strid = new string[24];//
            for (int i = 0; i < 24; i++)//把字符賦給數組
            {

            for (int i = 0; i < 24; i++)//從數組隨機抽取24個字符組成新的字符生成機器三
            {
                //temp += strid[rdid.Next(0, 24)];

            //}
            for (int i = 1; i < intCode.Length; i++)
            {
                intCode[i] = i + 3 > 9 ? 0 : i + 3;
            }
        }
