Since .Net 2.0 there's been a NetworkInterface class in the System.Net.NetworkInformation namespace that will give you this information. Try this:

<pre><code> foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
 {
 if (nic.OperationalStatus == OperationalStatus.Up)
 {
 Console.WriteLine(nic.GetPhysicalAddress().ToString());
 break;

It looks like this is an old post but I know that you will run into this thread looking for help so here is what I did today to get the MAC addresses of all the network interfaces in my Laptop. 

First of all you have to import the following

<pre><code>Imports System.Net.NetworkInformation
</code></pre>

This is the function that returns all the MAC addresses in an string array

<pre><code>Private Function GetMAC() As String()
 Dim MACAddresses(0) As String
 Dim i As Integer = 0
 Dim NIC As NetworkInterface

 For Each NIC In NetworkInterface.GetAllNetworkInterfaces
 ReDim Preserve MACAddresses(i)
 MACAddresses(i) = String.Format("{0}", NIC.GetPhysicalAddress())
 i += 1
 Next
 Return MACAddresses
End Function
</code></pre>

// ...
private void GetNetworkAdaptorName()
{
 // The initial call is to determine the size of the memory required. This will fail
 // with the error code "111" which is defined by MSDN to be "ERROR_BUFFER_OVERFLOW".
 // The structure size should be 640 bytes per adaptor.
 int nSize = 0;
 int nReturn = GetAdaptersInfo(null, ref nSize);

 // Allocate memory and get data
 byte[] abyAdapatorInfo = new byte[nSize];
 nReturn = GetAdaptersInfo(abyAdapatorInfo, ref nSize);
 if (nReturn == 0)
 {
 // Find the start and end bytes of the name in the returned structure
 int nStartNamePos = 8;
 int nEndNamePos = 8;
 while ((abyAdapatorInfo[nEndNamePos] != 0) &amp;&amp;
 ((nEndNamePos - nStartNamePos) &lt; MAX_ADAPTER_NAME_LENGTH))
 {
 // Another character in the name
 nEndNamePos++;
 }

 // Convert the name from a byte array into a string
 m_szAdaptorName = Encoding.UTF8.GetString(
 abyAdapatorInfo, nStartNamePos, (nEndNamePos - nStartNamePos));
 }
 else
 {
 // Failed? Use a hard-coded network adaptor name.
 m_szAdaptorName = "DM9CE1";
