The event handler receives an argument of type MonitorEventArgs containing data related to this event. The following MonitorEventArgs properties provide information specific to this event.
The following sample shows how to enable and disable monitoring of database activity in your application.
static void OnEvent(object sender, MonitorEventArgs e)
{
if (e.TracePoint==MonitorTracePoint.BeforeEvent)
{
Console.WriteLine("Description: " + e.Description);
Console.WriteLine(" Extra info: " + e.ExtraInfo);
}
}
