Get the MAC Address of the physical network adapter

Dear all,
I'm looking for a way to find in VB NET the MAC Address of the network card installed on the pc, I mean not VPN, not any other kind of virtual network adapter, just the MAC of the card inside the pc, even if it's disabled.
Please see the function I wrote below, now I just avoid the NetworkInterfaceType=Tunnel, but how can I be sure to find the physical card? NetworkInterface type has so many values....
http://msdn.microsoft.com/en-us/library/system.net.networkinformation.networkinterfacetype.aspx

Public Function GetMacAddress() As String
        Dim theNetworkInterfaces() As System.Net.NetworkInformation.NetworkInterface =   System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces()
 
        Dim currentInterface As System.Net.NetworkInformation.NetworkInterface
 
        For Each currentInterface In theNetworkInterfaces
            If currentInterface.NetworkInterfaceType <>   Net.NetworkInformation.NetworkInterfaceType.Tunnel Then
                GetMacAddress = currentInterface.GetPhysicalAddress().ToString()
                Exit For
            End If
        Next
 
    End Function

using System.Management;

string MacAddress = "";
try
{
ManagementClass myManagementClass = new
ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = myManagementClass.GetInstances();

foreach(ManagementObject mo in moc)
{
MacAddress = mo["MacAddress"].ToString();
break;
}
}

renjurdevan

Imports System.Management

Dim MacAddress As string

Dim myManagementClass As New ManagementClass("Win32_NetworkAdapterConfiguration")

Dim moc As ManagementObjectCollection = myManagementClass.GetInstances()

For Each ManagementObject mo in moc
MacAddress = mo("MacAddress").ToString()
Next

Console.WriteLine (MacAddress )

Make sure that System.Mangement dll included in your application

Dear renjurdean,
I think you did not catch my question.

I have already found the solution to get ALL the MAC of all the network adapter (see the first code I posted), I just want to get the one of the card installed on the pc, only that one.
How can I be sure?

Thanks

renjurdevan

moc as ManagementObjectCollection (Collection) so you should enumerate it!
foreach(ManagementObject mo in moc)
{
MacAddress = mo["MacAddress"].ToString();
break;
}

Check myManagementClass' s methods
