L’exemple de code suivant illustre l’utilisation de la NotifyIcon classe pour afficher une icône pour une application dans la zone de notification. L’exemple illustre la définition des Iconpropriétés , ContextMenu, Textet et Visible et la gestion de l’événement DoubleClick . Un ContextMenu avec un élément Exit est affecté à la NotifyIcon.ContextMenu propriété, ce qui permet à l’utilisateur de fermer l’application. Lorsque l’événement DoubleClick se produit, le formulaire d’application est activé en appelant la Form.Activate méthode .
