PhysicalAddress Obiekt, który zawiera adres fizyczny.

Przykłady

Poniższy przykład kodu przedstawia fizyczne adresy wszystkich interfejsów na komputerze lokalnym.

void DisplayTypeAndAddress()
{
   IPGlobalProperties ^ computerProperties = IPGlobalProperties::GetIPGlobalProperties();
   array<NetworkInterface^>^nics = NetworkInterface::GetAllNetworkInterfaces();
   Console::WriteLine( "Interface information for {0}.{1}     ", computerProperties->HostName, computerProperties->DomainName );
   System::Collections::IEnumerator^ myEnum27 = nics->GetEnumerator();
   while ( myEnum27->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum27->Current);
      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() );
      Console::WriteLine( "  Is receive only.......................... : {0}", 
         adapter->IsReceiveOnly );
      Console::WriteLine( "  Multicast................................ : {0}", 
         adapter->SupportsMulticast );
   }
}

    IPGlobalProperties computerProperties = IPGlobalProperties.GetIPGlobalProperties();
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    Console.WriteLine("Interface information for {0}.{1}     ",

Uwagi

Obiekt zwrócony przez tę metodę zawiera adres odpowiedni dla nośnika używanego do transportu danych w warstwie łącza danych. Na przykład w sieci Ethernet ta metoda zwraca adres sprzętowy Ethernet.
