Um PhysicalAddress objeto que contém o endereço físico.

Exemplos

O seguinte exemplo de código mostra os endereços físicos de todas as interfaces no computador local.

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();
      }
   }

Public Shared Sub DisplayTypeAndAddress() 
    Dim computerProperties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim nics As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Console.WriteLine("Interface information for {0}.{1}     ", computerProperties.HostName, computerProperties.DomainName)
    Dim adapter As NetworkInterface
    For Each adapter In  nics
        Dim properties As IPInterfaceProperties = adapter.GetIPProperties()
        Console.WriteLine(adapter.Description)
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length, "="c))
        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)
    Next adapter

End Sub

Observações

O objeto devolvido por este método contém um endereço apropriado ao meio utilizado para transportar dados na camada de ligação de dados. Por exemplo, numa rede Ethernet, este método devolve o endereço de hardware Ethernet.
