傳回

PhysicalAddress 物件,包含實體位址。A PhysicalAddress object that contains the physical address.

範例

下列程式碼範例會顯示本機電腦上的所有介面實體位址。The following code example displays the physical addresses of all interfaces on the local computer.

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 );
   }
}

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

        Console.WriteLine("  Interface type .......................... : {0}", adapter.NetworkInterfaceType);
        Console.WriteLine("  Physical Address ........................ : {0}", 
                   adapter.GetPhysicalAddress().ToString());
        Console.WriteLine("  Is receive only.......................... : {0}", adapter.IsReceiveOnly);

備註

這個方法所傳回的物件會包含適合用來傳輸資料,在資料連結層媒體的位址。The object returned by this method contains an address that is appropriate to the media used to transport data at the data link layer. 例如,乙太網路,這個方法會傳回乙太網路硬體位址。For example, on an Ethernet network, this method returns the Ethernet hardware address.
