SoapAttributeAttribute.DataType-Eigenschaft

  • Artikel

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

Namespace: System.Xml.Serialization
Assembly: System.Xml (in system.xml.dll)

Syntax

'Declaration
Public Property DataType As String
'Usage
Dim instance As SoapAttributeAttribute
Dim value As String

value = instance.DataType

instance.DataType = value

public string DataType { get; set; }

public:
property String^ DataType {
    String^ get ();
    void set (String^ value);
}

/** @property */
public String get_DataType ()

/** @property */
public void set_DataType (String value)

public function get DataType () : String

public function set DataType (value : String)

Eigenschaftenwert

Ein XML-Schemadatentyp laut Definition im Dokument "XML Schema Part 2: Datatypes" des World Wide Web Consortium (www.w3.org ).

Ausnahmen

Ausnahmetyp Bedingung

Exception

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

Hinweise

In der folgenden Tabelle sind die einfachen Datentypen des XML-Schemas und ihre Entsprechungen in .NET aufgelistet.

Verwenden Sie beim XML-Schemadatentyp base64Binary und hexBinary ein Array von Byte-Strukturen, und weisen Sie ein SoapAttributeAttribute zu, wobei DataType auf "base64Binary" bzw. "hexBinary" festgelegt wird. Verwenden Sie beim XML-Schemadatentyp time und date den DateTime-Typ, und weisen Sie das SoapAttributeAttribute zu, wobei DataType auf "date" oder "time" festgelegt ist.

Weisen Sie bei jedem einer Zeichenfolge zugeordneten XML-Schemadatentyp das SoapAttributeAttribute zu, wobei die DataType-Eigenschaft auf den XML-Schemadatentyp festgelegt ist. Beachten Sie, dass dadurch nicht das Serialisierungsformat geändert wird, sondern nur das Schema für den Member.

Hinweis

Bei der Eigenschaft wird die Groß- und Kleinschreibung berücksichtigt, sodass diese genau auf einen der XML-Schemadatentypen festgelegt werden muss.

Hinweis

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

Weitere Informationen über XML-Schemadatentypen finden Sie im Dokument "XML Schema Part 2: Datatypes" des World Wide Web Consortium (www.w3.org).
