NetworkInterface.GetPhysicalAddress メソッド

定義

名前空間:

System.Net.NetworkInformation

アセンブリ:

System.Net.NetworkInformation.dll

ソース:

NetworkInterface.cs

このアダプターのメディア アクセス制御 (MAC) アドレスまたは物理アドレスを返します。

public:
 virtual System::Net::NetworkInformation::PhysicalAddress ^ GetPhysicalAddress();

public virtual System.Net.NetworkInformation.PhysicalAddress GetPhysicalAddress ();

abstract member GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress
override this.GetPhysicalAddress : unit -> System.Net.NetworkInformation.PhysicalAddress

Public Overridable Function GetPhysicalAddress () As PhysicalAddress

戻り値

PhysicalAddress

物理アドレスを格納している PhysicalAddress オブジェクト。

例

次のコード例では、ローカル コンピューター上のすべてのインターフェイスの物理アドレスを表示します。

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.GetPhysicalAddress().ToString());
        Console.WriteLine("  Is receive only.......................... : {0}", adapter.IsReceiveOnly);
        Console.WriteLine("  Multicast................................ : {0}", adapter.SupportsMulticast);
        Console.WriteLine();
      }
