Exemples

L’exemple de code suivant affiche des statistiques pour les interfaces IPV4 sur l’ordinateur local.

public static void DisplayIPv4NetworkInterfaces()

    Console.WriteLine("IPv4 interface information for {0}.{1}",
       properties.HostName, properties.DomainName);
    Console.WriteLine();

    foreach (NetworkInterface adapter in nics)
    {
        // Only display informatin for interfaces that support IPv4.
        if (!adapter.Supports(NetworkInterfaceComponent.IPv4))
        {
            continue;
        }

        // Underline the description.
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
