SoapAttributeAttribute.DataType Eigenschaft

Definition

Ruft den XSD (XML Schema Definition)-Datentyp des von XmlSerializer generierten SOAP-Attributs ab oder legt diesen fest.

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

Eigenschaftswert

Ein XML-Schemadatentyp.

Ausnahmen

Der angegebene XML-Schemadatentyp kann dem .NET-Datentyp nicht zugeordnet werden.

Beispiele

Im folgenden Beispiel wird eine Klasse serialisiert, die mehrere Felder enthält, auf die ein SoapAttributeAttribute angewendet wird. Die DataType -Eigenschaft wird für die GroupNumber Felder und Today festgelegt.

Hinweise

In der folgenden Tabelle sind die einfachen XML-Schema-Datentypen mit their.NET Entsprechungen aufgeführt.

Verwenden Sie für das XML-Schema base64Binary und hexBinary die Datentypen ein Array von Byte Strukturen, und wenden Sie nach Bedarf ein SoapAttributeAttribute an, wobei DataType "base64Binary" oder "hexBinary" festgelegt ist. Verwenden Sie für das XML-Schema time und date die Datentypen den DateTime Typ, und wenden Sie den SoapAttributeAttribute an, wobei auf DataType "Datum" oder "Uhrzeit" festgelegt ist.

Wenden Sie für jeden XML-Schemadatentyp, der einer Zeichenfolge zugeordnet ist, die SoapAttributeAttributeDataType -Eigenschaft an, die auf den XML-Schemadatentyp festgelegt ist. Beachten Sie, dass dadurch das Serialisierungsformat nicht geändert wird, nur das Schema für den Member.

Hinweis

Bei der Eigenschaft wird die Groß-/Kleinschreibung beachtet, sodass Sie sie genau auf einen der XML-Schemadatentypen festlegen müssen.

Hinweis

Das Übergeben von Binärdaten als XML-Element ist effizienter als die Übergabe als XML-Attribut.

Weitere Informationen zu XML-Schema-Datentypen finden Sie im Dokument des World Wide Consortium mit dem Namen XML Schema Part 2: Datatypes](https://www.w3.org/TR/xmlschema-2/).
