Using ping in c#

When I Ping a remote system with windows it says there is no reply, but when I ping with c# it says success. Windows is correct, the device is not connected. Why is my code able to successfully ping when Windows is not?

Here is my code :

Ping p1 = new Ping();
PingReply PR = p1.Send("192.168.2.18");
// check when the ping is not success
while (!PR.Status.ToString().Equals("Success"))
{
    Console.WriteLine(PR.Status.ToString());
    PR = p1.Send("192.168.2.18");
}
// check after the ping is n success
while (PR.Status.ToString().Equals("Success"))
{
    Console.WriteLine(PR.Status.ToString());
    PR = p1.Send("192.168.2.18");
}

Public Function PingHost(ByVal nameOrAddress As String) As Boolean
    Dim pingable As Boolean = False
    Dim pinger As Ping
    Dim lPingReply As PingReply

    Try
        pinger = New Ping()
        lPingReply = pinger.Send(nameOrAddress)
        MessageBox.Show(lPingReply.Status)
        If lPingReply.Status = IPStatus.Success Then

            pingable = True
        Else
            pingable = False
        End If


    Catch PingException As Exception
        pingable = False
    End Try
    Return pingable
End Function
