Get MAC Address when network adapter is disabled?

Question

Hi All,

Is there any way i can retrieve MAC Address when Network Adapter is disabled in .net?

Thanks in advance,

Answer 1

You can parse the output of the "ipconfig /all" command.

Also, you can use the GetAdaptersInfo WINAPI function.

It might be possible to use the ManagementClass and Windows Management Instrumentation.
I have never tried that for disabled adapters though.

You can use WMI:

public static string GetMACAddress()
    {
        ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
        ManagementObjectCollection moc = mc.GetInstances();
        string MACAddress=String.Empty;
        foreach(ManagementObject mo in moc)
        {
            if(MACAddress==String.Empty)  // only return MAC Address from first card
            {
                MACAddress= mo["MacAddress"].ToString() ;
            }
            mo.Dispose();
        }

        return MACAddress;
    }

The example here displays physical address of all interface irrespective of their operational stage. HTH.
