 virtual System::Net::NetworkInformation::PhysicalAddress ^ GetPhysicalAddress();
public:
 abstract System::Net::NetworkInformation::PhysicalAddress ^ GetPhysicalAddress();
public virtual System.Net.NetworkInformation.PhysicalAddress GetPhysicalAddress ();
public abstract System.Net.NetworkInformation.PhysicalAddress GetPhysicalAddress ();
abstract member GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress
override this.GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress
abstract member GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress
Public Overridable Function GetPhysicalAddress () As PhysicalAddress
Public MustOverride Function GetPhysicalAddress () As PhysicalAddress

Mengembalikan

Objek PhysicalAddress yang berisi alamat fisik.

Contoh

Contoh kode berikut menampilkan alamat fisik semua antarmuka di komputer lokal.

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, '=' ) );
