Exemples

Voici un exemple de validation au moment du chargement. Une validation de XmlReader type de document (DTD) est passée à la Load méthode et un ValidationEventHandler document est fourni pour informer les utilisateurs des erreurs de validation. Dans cet exemple, une erreur de validation est trouvée, mais le document est toujours chargé. Vous pouvez également définir une validation XmlReader pour lever une exception et arrêter le processus de chargement lorsqu’une erreur de validation est trouvée en ne spécifiant pas le ValidationEventHandler. Pour plus d’informations sur la validation des données XML, consultez la section Remarques de la XmlReader page de référence.
