Remarques

La Namespace propriété vous permet de définir un nom unique pour l’attribut XML. La Namespace propriété est conforme aux règles de création d’un espace de noms XML, comme indiqué dans le document Espaces de noms dans XML du World Wide Web Consortium.

Pour définir la Namespace propriété sur un nom préfixé, créez un XmlSerializerNamespaces qui contient les espaces de noms et les préfixes utilisés dans le document XML. Définissez la Namespace propriété sur l’un des espaces de noms dans .XmlSerializerNamespaces Lorsque le code XML est généré, le nom d’attribut est correctement préfixé avec le préfixe associé à l’espace de noms spécifié.
