Try this:

 var macAddr =
              (from nic in NetworkInterface.GetAllNetworkInterfaces()
               where nic.OperationalStatus == OperationalStatus.Up
               select nic.GetPhysicalAddress().GetAddressBytes()).FirstOrDefault();

 string formattedMacAddr = string.Join (":", (from z in macAddr select z.ToString ("X2")).ToArray());
 Console.WriteLine(formattedMacAddr);

//outputs this format: 08:00:27:52:83:A8
