首先需新增對System.Management的引用。

使用方法舉例：

//獲取硬碟序列號 Hardware.HardwareInfo hardwareInfo = new Hardware.HardwareInfo(); string hardDiskID = hardwareInfo.GetHardDiskID(); System.Console.WriteLine(hardDiskID); //獲取CPU序列號 string cpuID = hardwareInfo.GetCpuID(); System.Console.WriteLine(cpuID); //獲取硬碟序列號Hardware.HardwareInfo hardwareInfo = new Hardware.HardwareInfo();string hardDiskID = hardwareInfo.GetHardDiskID();System.Console.WriteLine(hardDiskID);//獲取CPU序列號string cpuID = hardwareInfo.GetCpuID();System.Console.WriteLine(cpuID);
