Exemplos

O exemplo de código a seguir escuta as alterações de endereço e exibe o status dos adaptadores de rede quando ocorre um NetworkAddressChanged evento.

using System;
using System.Net;
using System.Net.NetworkInformation;

namespace Examples.Net.AddressChanges
{
    public class NetworkingExample
    {
        public static void Main()
        {
            NetworkChange.NetworkAddressChanged += new
            NetworkAddressChangedEventHandler(AddressChangedCallback);
            Console.WriteLine("Listening for address changes. Press any key to exit.");
            Console.ReadLine();
        }
        static void AddressChangedCallback(object sender, EventArgs e)
        {

            NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
            foreach(NetworkInterface n in adapters)
            {
                Console.WriteLine("   {0} is {1}", n.Name, n.OperationalStatus);
            }
        }
    }
}

Imports System.Net
Imports System.Net.NetworkInformation

Public Class NetworkingExample
    Public Shared Sub Main()
        AddHandler NetworkChange.NetworkAddressChanged, AddressOf AddressChangedCallback
        Console.WriteLine("Listening for address changes. Press any key to exit.")
        Console.ReadLine()
    End Sub
    Private Shared Sub AddressChangedCallback(ByVal sender As Object, ByVal e As EventArgs)

        Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
        Dim n As NetworkInterface
        For Each n In adapters
            Console.WriteLine("   {0} is {1}", n.Name, n.OperationalStatus)
        Next n
    End Sub

Comentários

A NetworkChange classe gera NetworkAddressChanged eventos quando o endereço de um adaptador de rede, também chamado de cartão de rede ou adaptador, é alterado.

Para que um NetworkChange objeto chame um método de tratamento de eventos quando ocorrer um NetworkAddressChanged evento, você deve associar o método a um NetworkAddressChangedEventHandler delegado e adicionar esse delegado a esse evento.
