Remarques

Si le nom de la classe n’est pas spécifié lors de la construction de l’objet, la chaîne de texte par défaut héritée de la classe de base est retournée.If the class name is not specified when the object is constructed, the default text string inherited from the base class is returned.

Cette propriété remplace Message .This property overrides Message. Le message d’erreur doit être localisé.The error message should be localized.
