Remarques

La classe SoapAttributeAttribute appartient à une famille d’attributs qui contrôle la façon dont le XmlSerializer sérialise, ou désérialise, un objet en tant que code XML SOAP encodé.The SoapAttributeAttribute class belongs to a family of attributes that controls how the XmlSerializer serializes, or deserializes, an object as encoded SOAP XML. Le XML obtenu est conforme à la section 5 du document World Wide Web Consortium, SOAP (Simple Object Access Protocol) 1,1.The resulting XML conforms to section 5 of the World Wide Web Consortium document, Simple Object Access Protocol (SOAP) 1.1. Pour obtenir la liste complète des attributs similaires, consultez attributs qui contrôlent la sérialisation encodée selon le protocole SOAP.For a complete list of similar attributes, see Attributes That Control Encoded SOAP Serialization.

Pour sérialiser un objet en tant que message SOAP encodé, vous devez construire le XmlSerializer à l’aide d’un XmlTypeMapping créé avec la méthode ImportTypeMapping de la classe SoapReflectionImporter.To serialize an object as an encoded SOAP message, you must construct the XmlSerializer using an XmlTypeMapping created with the ImportTypeMapping method of the SoapReflectionImporter class.

Appliquez la SoapAttributeAttribute à un champ public pour spécifier que le XmlSerializer sérialise le champ en tant qu’attribut XML.Apply the SoapAttributeAttribute to a public field to specify that the XmlSerializer serializes the field as an XML attribute. Vous pouvez spécifier un autre nom de l’attribut en définissant la propriété AttributeName.You can specify an alternative name of the attribute by setting the AttributeName property. Définissez le DataType si l’attribut doit recevoir un type de données XSD (XML Schema Definition Language) spécifique.Set the DataType if the attribute must be given a specific XML Schema definition language (XSD) data type. Si l’attribut appartient à un espace de noms XML spécifique, définissez la propriété Namespace.If the attribute belongs to a specific XML namespace, set the Namespace property.

Pour plus d’informations sur l’utilisation des attributs, consultez attributs .For more information about using attributes, see Attributes

Notes

Vous pouvez utiliser le mot SoapAttribute dans votre code au lieu du SoapAttributeAttributeplus long.You can use the word SoapAttribute in your code instead of the longer SoapAttributeAttribute.
