SoapAttributeAttribute.DataType Propriété

Définition

Obtient ou définit le type de données XSD (XML Schema Definition) de l'attribut SOAP généré par XmlSerializer.

public:
 property System::String ^ DataType { System::String ^ get(); void set(System::String ^ value); };
public string DataType { get; set; }
member this.DataType : string with get, set
Public Property DataType As String

Valeur de propriété

Type de données de schéma XML.

Exceptions

Le type de données de schéma XML que vous avez spécifié ne peut pas être mappé au type de données .NET.

Remarques

Le tableau suivant répertorie les types de données simples de schéma XML avec their.NET équivalents.

Pour le schéma base64Binary XML et hexBinary les types de données, utilisez un tableau de Byte structures et appliquez un SoapAttributeAttribute avec la DataType valeur « base64Binary » ou « hexBinary », le cas échéant. Pour le schéma time XML et date les types de données, utilisez le DateTime type et appliquez le SoapAttributeAttribute avec la DataType valeur « date » ou « heure ».

Pour chaque type de données de schéma XML mappé à une chaîne, appliquez le SoapAttributeAttribute avec sa DataType propriété définie sur le type de données schéma XML. Notez que cela ne modifie pas le format de sérialisation, mais uniquement le schéma du membre.

Notes

La propriété respecte la casse. Vous devez donc la définir exactement sur l’un des types de données de schéma XML.

Notes

Le passage de données binaires en tant qu’élément XML est plus efficace que le passage en tant qu’attribut XML.

Pour plus d’informations sur les types de données de schéma XML, consultez le document du World Wide Consortium intitulé XML Schema Part 2: Datatypes](https://www.w3.org/TR/xmlschema-2/).
