C # obtain the CPU serial number, hard disk ID, and nic MAC address

Sometimes you need to obtain information about some hardware devices on the computer in C #, such as the CPU serial number and hard disk ID ,.. Net System. management. managementclass supports device management, which indicates the CIM management class. The management class is a WMI class, such as win32_logicaldisk and win32_process. The former indicates the disk drive, and the latter indicates the process (such as notepad.exe ). Members of this class can access WMI data using specific WMI class paths. For more information, see the Win32 classes (Win32 class) in the Windows Management Instrumentation document, which is located in the msdn library on the http://www.microsoft.com/china/msdn/library.

// Obtain the CPU serial number
String cpuinfo = "";
Managementclass cimobject = new managementclass ("win32_processor ");
Managementobjectcollection MOC = cimobject. getinstances ();
Foreach (managementobject Mo in MoC)
{
If (Mo. properties ["processorid"]. value! = NULL)
Cpuinfo + = Mo. properties ["processorid"]. value. tostring ();
}
Result + = cpuinfo;

// obtain the hard disk id
string Hdid = "";
managementclass cimobject1 = new managementclass ("win32_diskdrive ");
managementobjectcollection moc1 = cimobject1.getinstances ();
foreach (managementobject Mo in moc1)
{< br> If (MO. properties ["model"]. value! = NULL)
Hdid + = (string) Mo. properties ["model"]. value. tostring ();
}< br> result + = Hdid;

// Obtain the hardware address of the NIC
String macaddress = "";
Managementclass MC = new managementclass ("win32_networkadapterconfiguration ");
Managementobjectcollection moc2 = mc. getinstances ();
Foreach (managementobject Mo in moc2)
{
If (bool) Mo ["ipenabled"] = true & Mo ["macaddress"]! = NULL)
Macaddress + = Mo ["macaddress"]. tostring ();
Mo. Dispose ();
}
Result + = macaddress;
