Ejemplos

En el ejemplo de código siguiente se muestran las direcciones físicas de todas las interfaces del equipo 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

Comentarios

El objeto devuelto por este método contiene una dirección adecuada para el medio utilizado para transportar datos en la capa de vínculo de datos. Por ejemplo, en una red Ethernet, este método devuelve la dirección de hardware Ethernet.
