Example

The following example demonstrates pinging a remote host.

private void button1_Click(object sender, EventArgs e)
{
    ping1.Start(pingWorker, HostNameOrAddressToPingTextbox.Text);
}

private void pingWorker(PingSlave slave, object state)
{
    ping1.Marshal(slave.GetEchoes(new Dart.Sockets.IPEndPoint(state.ToString(), 0).Address, null, 20, 5000, false));
}

void ping1_Echo(object sender, EchoEventArgs e)
{
    string results = "The following echoes were returned:\r\n";
    for (int i = 0; i < e.Echoes.Length; i++)
        results += e.Echoes[i].ToString() + "\r\n";
    textBox1.AppendText(results);
}

Visual Basic

Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs)
    ping1.Start(AddressOf pingWorker, HostNameOrAddressToPingTextbox.Text)
End Sub

Private Sub pingWorker(ByVal slave As PingSlave, ByVal state As Object)
    ping1.Marshal(slave.GetEchoes((New Dart.Sockets.IPEndPoint(state.ToString(), 0)).Address, Nothing, 20, 5000, False))
End Sub

Private Sub ping1_Echo(ByVal sender As Object, ByVal e As EchoEventArgs)
    Dim results As String = "The following echoes were returned:" & vbCrLf
    For i As Integer = 0 To e.Echoes.Length - 1
        results &= e.Echoes(i).ToString() & vbCrLf
    Next i
    textBox1.AppendText(results)
End Sub
