Exemples

L’exemple suivant montre comment créer un FileUpload contrôle qui enregistre les fichiers dans un chemin d’accès spécifié dans le code. La FileName propriété est utilisée pour obtenir le nom du fichier à charger. La SaveAs méthode est appelée pour enregistrer le fichier dans le chemin d’accès spécifié sur le serveur, en utilisant le même nom que le fichier sur le client. Notez que cet exemple illustre la syntaxe de base de ce contrôle, mais n’illustre pas toutes les vérifications d’erreur nécessaires qui doivent être effectuées avant d’enregistrer le fichier. Pour un exemple plus complet, consultez SaveAs.
