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 einen SoapAttributeAttribute mit dem DataType Satz auf "base64Binary" oder "hexBinary" an, sofern zutreffend. Verwenden Sie für das XML-Schema time und date die Datentypen den DateTime Typ, und wenden Sie den SoapAttributeAttributeDataType Mitsatz auf "Datum" oder "Uhrzeit" an.

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

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