Remarques

La Type propriété ne peut être définie que sur des types primitifs et des énumérations.

Il XmlTextAttribute peut également être appliqué à un champ qui retourne un XmlNode tableau d’objets ou un tableau d’objets XmlNode .

Vous pouvez appliquer le XmlTextAttribute champ ou la propriété qui retourne un tableau de chaînes. Vous pouvez également appliquer l’attribut à un tableau de type Object , mais vous devez définir la Type propriété sur chaîne. Dans ce cas, toutes les chaînes insérées dans le tableau sont sérialisées en tant que texte XML.
