用C#获取硬盘序列号,CPU序列号,网卡MAC地址

private string[] GetMoc()
        {
            string[] str = new string[3];
            ManagementClass mcCpu = new ManagementClass("win32_Processor");
            ManagementObjectCollection mocCpu = mcCpu.GetInstances();
            foreach(ManagementObject m in mocCpu)
            {
                str[0] = m["UniqueID"].ToString();
            }

            ManagementClass mcHD = new ManagementClass("win32_logicaldisk");
            ManagementObjectCollection mocHD = mcHD.GetInstances();
            foreach(ManagementObject m in mocHD)
            {
                if(m["DeviceID"].ToString() == "C:")
                {
                    str[1] = m["VolumeSerialNumber"].ToString();
                    break;
                }
            }

            ManagementClass mcMAC = new ManagementClass("Win32_NetworkAdapterConfiguration");
            ManagementObjectCollection mocMAC = mcMAC.GetInstances();
            foreach(ManagementObject m in mocMAC)
            {
                if((bool)m["IPEnabled"])
                {
                    str[2] = m["MacAddress"].ToString();
                    break;
                }
            }

            return str;
        }
