OperationalStatus

Bidang

Dormant	5	Antarmuka jaringan tidak dalam kondisi untuk mengirimkan paket data; sedang menunggu peristiwa eksternal.
Down	2	Antarmuka jaringan tidak dapat mengirimkan paket data.
LowerLayerDown	7	Antarmuka jaringan tidak dapat mengirimkan paket data karena berjalan di atas satu atau beberapa antarmuka lain, dan setidaknya salah satu antarmuka "lapisan bawah" ini tidak berfungsi.
NotPresent	6	Antarmuka jaringan tidak dapat mengirimkan paket data karena komponen yang hilang, biasanya komponen perangkat keras.
Testing	3	Antarmuka jaringan sedang menjalankan pengujian.
Unknown	4	Status antarmuka jaringan tidak diketahui.
Up	1	Antarmuka jaringan sudah habis; ini dapat mengirimkan paket data.

Contoh

Contoh kode berikut menampilkan ringkasan untuk semua antarmuka di komputer lokal.

void ShowInterfaceSummary()
{
   array<NetworkInterface^>^interfaces = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum5 = interfaces->GetEnumerator();
   while ( myEnum5->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum5->Current);
      Console::WriteLine( "Name: {0}", adapter->Name );
      Console::WriteLine( adapter->Description );
      Console::WriteLine( String::Empty->PadLeft( adapter->Description->Length, '=' ) );
      Console::WriteLine( "  Interface type .......................... : {0}",
         adapter->NetworkInterfaceType );
      Console::WriteLine( "  Operational status ...................... : {0}", adapter->OperationalStatus );
      String^ versions = "";

      // Create a display string for the supported IP versions.
      if ( adapter->Supports( NetworkInterfaceComponent::IPv4 ) )
      {
         versions = "IPv4";
      }

      if ( adapter->Supports( NetworkInterfaceComponent::IPv6 ) )
      {
         if ( versions->Length > 0 )
         {
            versions = String::Concat( versions, " " );
         }

         versions = String::Concat( versions, "IPv6" );
      }

      Console::WriteLine( "  IP version .............................. : {0}", versions );
      Console::WriteLine();
   }

   Console::WriteLine();
}

public static void ShowInterfaceSummary()
{

    NetworkInterface[] interfaces = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in interfaces)
    {
        Console.WriteLine ("Name: {0}", adapter.Name);
        Console.WriteLine(adapter.Description);
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
        Console.WriteLine("  Interface type .......................... : {0}", adapter.NetworkInterfaceType);
        Console.WriteLine("  Operational status ...................... : {0}",
            adapter.OperationalStatus);
        string versions ="";

        // Create a display string for the supported IP versions.
        if (adapter.Supports(NetworkInterfaceComponent.IPv4))
        {
             versions = "IPv4";
         }
        if (adapter.Supports(NetworkInterfaceComponent.IPv6))
        {
            if (versions.Length > 0)
            {
                versions += " ";
             }
            versions += "IPv6";
        }
        Console.WriteLine("  IP version .............................. : {0}", versions);
        Console.WriteLine();
    }
    Console.WriteLine();
}

Keterangan

Enumerasi ini menentukan nilai yang OperationalStatus valid untuk properti .
