NetworkInterface.GetPhysicalAddress Method

Definition

Returns the Media Access Control (MAC) or physical address for this adapter.

public virtual System.Net.NetworkInformation.PhysicalAddress GetPhysicalAddress ();
public abstract System.Net.NetworkInformation.PhysicalAddress GetPhysicalAddress ();

Returns

A PhysicalAddress object that contains the physical address.

Examples

The following code example displays the physical addresses of all interfaces on the local computer.

public static void DisplayTypeAndAddress()
{
    IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    Console.WriteLine("Interface information for {0}.{1}     ",
            computerProperties.HostName, computerProperties.DomainName);
    foreach (NetworkInterface adapter in nics)
    {
        IPInterfaceProperties properties = adapter.GetIPProperties();
        Console.WriteLine(adapter.Description);
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
        Console.WriteLine("  Interface type .......................... : {0}", adapter.NetworkInterfaceType);
        Console.WriteLine("  Physical Address ........................ : {0}",
                   adapter.GetPhysicalAddress().ToString());
        Console.WriteLine("  Is receive only.......................... : {0}", adapter.IsReceiveOnly);
        Console.WriteLine("  Multicast................................ : {0}", adapter.SupportsMulticast);
        Console.WriteLine();
      }
   }

Remarks

The object returned by this method contains an address that is appropriate to the media used to transport data at the data link layer. For example, on an Ethernet network, this method returns the Ethernet hardware address.
