Using .Net read the MAC Address from Network adapter

Questions: If you like to be able to read the mac address from the first active network adapter using .Net Winform application. Solution: Since .Net 2.0 there's been a NetworkInterface class in the System.Net.NetworkInformation namespace that will give you this information. Try this:

        foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
        {
            if (nic.OperationalStatus == OperationalStatus.Up)
            {
                Console.WriteLine(nic.GetPhysicalAddress().ToString());
                break;
            }
        }
