Exemples

L’exemple suivant instancie un objet Timer qui déclenche son événement de Timer.Elapsed toutes les deux secondes (2000 millisecondes), configure un gestionnaire d’événements pour l’événement et démarre le minuteur. Le gestionnaire d’événements affiche la valeur de la propriété ElapsedEventArgs.SignalTime chaque fois qu’elle est déclenchée.
