    MonitorEventHandler Delegate
    In This Topic
    Represents the method that will handle the TraceEvent event of the DbMonitor class.
    Syntax
    'Declaration
     
    Public Delegate Sub MonitorEventHandler( _
       ByVal sender As Object, _
       ByVal e As MonitorEventArgs _
    ) 
    public delegate void MonitorEventHandler( 
       object sender,
       MonitorEventArgs e
    )

    Parameters

    sender
    The source of the event.
    e
    The MonitorEventArgs object that contains the event data.
    Remarks
    When you create a MonitorEventArgs delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see "Events and Delegates" in the .NET Framework SDK documentation.
    Example
    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);
      }
    }
