Valeur de propriété

String

Nom d'élément XML du tableau sérialisé. Par défaut, il s'agit du nom du membre auquel XmlArrayAttribute est assigné.

Exemples

L’exemple suivant sérialise une instance de la Library classe qui contient une propriété nommée Books qui retourne un tableau d’éléments Book . L’exemple utilise la propriété pour spécifier que le ElementName tableau d’éléments XML doit être nommé My_Books plutôt que Books.

Remarques

Spécifiez un ElementName moment où vous souhaitez que le nom d’élément XML généré diffère de l’identificateur du membre.

Vous pouvez définir la même ElementName valeur sur plusieurs membres tant que le document XML généré utilise des espaces de noms XML pour distinguer les membres nommés identiquement. Pour plus d’informations sur l’utilisation d’espaces de noms et la création de noms préfixés dans le document XML, consultez XmlSerializerNamespaces.
