क्लाइंट से आप
PingHost = new Ping();
PingHost.OnPingFailed += new Ping.PingFailedHandler(PingHost_OnPingFailed);
PingHost.OnPingReceived +=new Ping.PingReceivedHandler(PingHost_OnPingReceived);
PingHost.Host = *IP you wish to ping*;
PingHost.StartPinging();
फिर कहेंगे आप PingHost की घटनाओं से ऊपर
private void PingHost_OnPingReceived(object DataObj, PingReceivedArgs PingReceived)
{
try
{
// code to do something when a successful ping occurrs
}
catch (Exception ex)
{
// code to do something when an exception occurrs
}
}
private void PingHost_OnPingFailed(object DataObj, PingFailedArgs PingFailed)
{
try
{
// code to do something when a ping failure occurrs
}
catch (Exception ex)
{
// code to do something when an exception occurrs
}
}
