Een IPInterfaceProperties object dat deze netwerkinterface beschrijft.

Voorbeelden

In het volgende codevoorbeeld wordt informatie weergegeven voor de netwerkadapters van de lokale computer die IPv4 ondersteunen.

public static void DisplayIPv4NetworkInterfaces()
{
    NetworkInterface[] nics = NetworkInterface.GetAllNetworkInterfaces();
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    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;
        }
        Console.WriteLine(adapter.Description);
        // Underline the description.
        Console.WriteLine(String.Empty.PadLeft(adapter.Description.Length,'='));
        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        // Try to get the IPv4 interface properties.
        IPv4InterfaceProperties p = adapterProperties.GetIPv4Properties();

        // Display the IPv4 specific data.
        Console.WriteLine("  Index ............................. : {0}", p.Index);

Opmerkingen

De informatie in het object dat door deze methode wordt geretourneerd, weerspiegelt de interfaces vanaf het moment dat de matrix wordt gemaakt. Deze informatie wordt niet dynamisch bijgewerkt.
