PhysicalAddress

Een PhysicalAddress object dat het fysieke adres bevat.

Voorbeelden

In het volgende codevoorbeeld worden de fysieke adressen van alle interfaces op de lokale computer weergegeven.

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();
      }
   }

    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

Opmerkingen

Het object dat door deze methode wordt geretourneerd, bevat een adres dat geschikt is voor de media die worden gebruikt voor het transport van gegevens op de gegevenskoppelingslaag. Op een Ethernet-netwerk retourneert deze methode bijvoorbeeld het Ethernet-hardwareadres.
