Beispiele

Im folgenden Codebeispiel werden die physischen Adressen aller Schnittstellen auf dem lokalen Computer angezeigt.

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();
      }

Hinweise

Das von dieser Methode zurückgegebene Objekt enthält eine Adresse, die für die Medien geeignet ist, die zum Transport von Daten auf der Datenverbindungsebene verwendet werden. Beispielsweise gibt diese Methode in einem Ethernet-Netzwerk die Ethernet-Hardwareadresse zurück.
