Exemplos

O exemplo a seguir exibe as estatísticas atuais do ICMPv4.

public static void ShowIcmpV4Statistics()
{
    IPGlobalProperties properties = IPGlobalProperties.GetIPGlobalProperties();
    IcmpV4Statistics stat = properties.GetIcmpV4Statistics();
    Console.WriteLine("ICMP V4 Statistics:");

    Console.WriteLine("  Messages ............................ Sent: {0,-10}   Received: {1,-10}",
        stat.MessagesSent, stat.MessagesReceived);

Comentários

O ICMP é um conjunto de mensagens para uso com o Protocolo de Internet versão 4 (IPv4). O ICMP é usado por nós IPv4 para relatar erros encontrados no processamento de pacotes de dados e para executar outras funções de camada da Internet. O ICMP versão 4 é definido no IETF RFC 792.

Para obter detalhes sobre as estatísticas de tráfego do ICMP versão 4 que estão disponíveis para aplicativos, consulte a documentação da IcmpV4Statistics classe. Observe que o IcmpV4Statistics objeto retornado por esse método reflete as estatísticas a partir do momento em que o objeto é criado. Essas informações não são atualizadas dinamicamente.
