Formatting MAC address in C#

Question

In my C# application, I want to get my MAC address by using NetworkInterface class as the following:

NetworkInterface nic in NetworkInterface.Ge         


        

Answer 1

Using the comment by eFloh for using BitConverter I was able to do the following (assuming mac is predefined as a string).

foreach (NetworkInterface nic in NetworkInterface.GetAllNetworkInterfaces())
{
    mac = BitConverter.ToString(nic.GetPhysicalAddress().GetAddressBytes()).Replace('-', ':');

    //Do whatever else necessary with each mac...
}
