.net c# 如何获取物理硬盘序列号

通过 ManagementObjectSearcher 查询Win32_PhysicalMedia,然后使用 ManagementObject 遍历对象,提取中间的SerialNumber值,该值即为 物理硬盘序列号

        //获取物理硬盘序列号
        public string GetHardDiskSerialNumber()
        {
            try
            {
                ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");
                string sHardDiskSerialNumber = "";
                foreach (ManagementObject mo in searcher.Get())
                {
                    sHardDiskSerialNumber = mo["SerialNumber"].ToString().Trim();
                    break;
                }
                return sHardDiskSerialNumber;
            }
            catch
            {
                return "";
            }
        }
