Exemplos
O exemplo de código a seguir exibe os endereços de gateway para os adaptadores de rede no computador local.
void DisplayGatewayAddresses()
{
Console::WriteLine( "Gateways" );
array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
System::Collections::IEnumerator^ myEnum21 = adapters->GetEnumerator();
while ( myEnum21->MoveNext() )
{
NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum21->Current);
IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
GatewayIPAddressInformationCollection ^ addresses = adapterProperties->GatewayAddresses;
if ( addresses->Count > 0 )
{
Console::WriteLine( adapter->Description );
System::Collections::IEnumerator^ myEnum22 = addresses->GetEnumerator();
while ( myEnum22->MoveNext() )
{
GatewayIPAddressInformation^ address = safe_cast<GatewayIPAddressInformation^>(myEnum22->Current);
Console::WriteLine( " Gateway Address ......................... : {0}",
address->Address->ToString() );
}
Console::WriteLine();
}
}
}
public static void DisplayGatewayAddresses()
{
Console.WriteLine("Gateways");
NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in adapters)

Console.WriteLine(adapter.Description);
foreach (GatewayIPAddressInformation address in addresses)
{
Console.WriteLine(" Gateway Address ......................... : {0}",
address.Address.ToString());
}
Console.WriteLine();
}

}
Public Shared Sub DisplayGatewayAddresses()
Console.WriteLine("Gateways")
Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
Dim adapter As NetworkInterface
For Each adapter In adapters
Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
Dim addresses As GatewayIPAddressInformationCollection = adapterProperties.GatewayAddresses
If addresses.Count > 0 Then
Console.WriteLine(adapter.Description)

For Each address In addresses
