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);
}
}

static void Main(string[] args)
{

"DataSource=mydatabase.db;");
SQLiteMonitor sqMonitor = new SQLiteMonitor();
sqMonitor.TraceEvent += new MonitorEventHandler(OnEvent);
sqMonitor.IsActive = true;
SQLiteCommand sqCommand = new SQLiteCommand("select count(*) from Dept",sqConn);
sqConn.Open();
Console.WriteLine(sqCommand.ExecuteScalar());
sqConn.Close();
sqMonitor.TraceEvent -= new MonitorEventHandler(OnEvent);
Console.ReadLine();
}
Sub OnEvent(ByVal sender As Object, ByVal e As MonitorEventArgs)
If e.TracePoint = MonitorTracePoint.BeforeEvent Then
Console.WriteLine("Description: " & e.Description)
Console.WriteLine(" Extra info: " & e.ExtraInfo)
