場景

首先獲取設備硬碟的捲標號，然後獲取CPU的序列號，將這兩個拼接成機器碼。

實現

新建一個Winform程式，然後添加Management引用

然後進入Form1頁面的代碼中

首先獲取設備硬碟的捲標號代碼

        public string GetDiskVolumeSerialNumber()
        {
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"d:\"");
            disk.Get();
            return disk.GetPropertyValue("VolumeSerialNumber").ToString();
        }

然後是獲取CPU的序列號的代碼

       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;
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            label1.Text = getCpu() + GetDiskVolumeSerialNumber();//獲得24位Cpu和硬碟序列號
            
        }
        //取得設備硬碟的捲標號
        public string GetDiskVolumeSerialNumber()
        {
            ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"d:\"");
            disk.Get();
            return disk.GetPropertyValue("VolumeSerialNumber").ToString();
        }
        //獲得CPU的序列號

            ManagementObjectCollection myCpuConnection = myCpu.GetInstances();
            foreach (ManagementObject myObject in myCpuConnection)
            {
                strCpu = myObject.Properties["Processorid"].Value.ToString();
                break;
            }
            return strCpu;
        }
    }
