Valeur de propriété

IPAddressCollection

Qui IPAddressCollection contient les informations d’adresse pour les serveurs DHCP ou un tableau vide si aucun serveur n’est trouvé.

UnsupportedOSPlatformAttribute

Exemples

L’exemple de code suivant affiche les informations d’adresse DHCP pour les interfaces réseau sur l’ordinateur local.

public static void DisplayDhcpServerAddresses()
{
    Console.WriteLine("DHCP Servers");
    NetworkInterface[] adapters  = NetworkInterface.GetAllNetworkInterfaces();
    foreach (NetworkInterface adapter in adapters)
    {

        IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
        IPAddressCollection addresses = adapterProperties.DhcpServerAddresses;
        if (addresses.Count >0)
        {
            Console.WriteLine(adapter.Description);
            foreach (IPAddress address in addresses)
            {
                Console.WriteLine("  Dhcp Address ............................ : {0}",
                    address.ToString());
            }
            Console.WriteLine();
        }
    }
}

Public Shared Sub DisplayDhcpServerAddresses() 
    Console.WriteLine("DHCP Servers")
    Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
    Dim adapter As NetworkInterface
    For Each adapter In  adapters
        
        Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
        Dim addresses As IPAddressCollection = adapterProperties.DhcpServerAddresses
        If addresses.Count > 0 Then
            Console.WriteLine(adapter.Description)
            Dim address As IPAddress
            For Each address In  addresses
                Console.WriteLine("  Dhcp Address ............................ : {0}", address.ToString())
            Next address

    Next adapter

End Sub

Remarques

Le protocole DHCP (Dynamic Host Configuration Protocol) permet à un ordinateur d’obtenir une adresse réseau auprès d’un serveur DHCP, par opposition à l’utilisation d’une adresse réseau statique (fixe). Un serveur DHCP n’affecte pas définitivement d’adresses ; Au lieu de cela, il utilise temporairement l’une des adresses disponibles pour l’ordinateur.
