Comment : ajouter des fonctionnalités de navigateur Web à une application Windows Forms
Avec le contrôle WebBrowser, vous pouvez ajouter des fonctionnalités de navigateur Web à votre application. Par défaut, le contrôle fonctionne comme un navigateur Web. Après avoir chargé une URL initiale en définissant la propriété Url, vous pouvez naviguer en cliquant sur des liens hypertexte ou en utilisant des raccourcis clavier pour vous déplacer, en avant et en arrière, dans l'historique de navigation. Par défaut, vous pouvez accéder à d'autres fonctionnalités de navigateur par le biais du menu contextuel, accessible par un clic droit de la souris. Vous pouvez également ouvrir de nouveaux documents en les déposant sur le contrôle. Le contrôle WebBrowser possède également plusieurs propriétés, méthodes et événements que vous pouvez utiliser pour implémenter des fonctionnalités d'interface utilisateur semblables à celles d'Internet Explorer.
L'exemple de code suivant implémente une barre d'adresses, des boutons de navigateur par défaut, un menu Fichier, une barre d'état et une barre de titre qui affiche le titre de la page en cours.
