        statistics.EchoRequestsSent, statistics.EchoRequestsReceived);
    Console.WriteLine("  Echo Replies ........................ Sent: {0,-10}   Received: {1,-10}",
        statistics.EchoRepliesSent, statistics.EchoRepliesReceived);
}

Public Shared Sub ShowIcmpV4EchoData() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim statistics As IcmpV4Statistics = properties.GetIcmpV4Statistics()
    Console.WriteLine("  Echo Requests ....................... Sent: {0,-10}   Received: {1,-10}", statistics.EchoRequestsSent, statistics.EchoRequestsReceived)
    Console.WriteLine("  Echo Replies ........................ Sent: {0,-10}   Received: {1,-10}", statistics.EchoRepliesSent, statistics.EchoRepliesReceived)

End Sub

備註
