Hinweise

Die SoapAttributeAttribute-Klasse gehört zu einer Reihe von Attributen, mit denen gesteuert wird, XmlSerializer wie ein Objekt als codiertes SOAP-XML serialisiert oder deserialisiert wird.The SoapAttributeAttribute class belongs to a family of attributes that controls how the XmlSerializer serializes, or deserializes, an object as encoded SOAP XML. Das resultierende XML entspricht Abschnitt 5 des World Wide Web Consortium Dokuments, Simple Object Access Protocol (SOAP) 1,1.The resulting XML conforms to section 5 of the World Wide Web Consortium document, Simple Object Access Protocol (SOAP) 1.1. Eine umfassende Liste mit ähnlichen Attributen finden Sie unter Attribute zur Steuerung der Serialisierung von codiertem SOAP.For a complete list of similar attributes, see Attributes That Control Encoded SOAP Serialization.

Wenn Sie ein Objekt als codierte SOAP-Nachricht serialisieren möchten, müssen Sie die XmlSerializer mit einer XmlTypeMapping erstellen, die mit der ImportTypeMapping-Methode der SoapReflectionImporter-Klasse erstellt wurde.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.

Wenden Sie den SoapAttributeAttribute auf ein öffentliches Feld an, um anzugeben, dass das-XmlSerializer das Feld als XML-Attribut serialisiert.Apply the SoapAttributeAttribute to a public field to specify that the XmlSerializer serializes the field as an XML attribute. Sie können einen alternativen Namen für das Attribut angeben, indem Sie die AttributeName-Eigenschaft festlegen.You can specify an alternative name of the attribute by setting the AttributeName property. Legen Sie die DataType fest, wenn dem Attribut ein bestimmter XSD-Datentyp (XML Schema Definition Language) zugewiesen werden muss.Set the DataType if the attribute must be given a specific XML Schema definition language (XSD) data type. Wenn das Attribut zu einem bestimmten XML-Namespace gehört, legen Sie die Namespace-Eigenschaft fest.If the attribute belongs to a specific XML namespace, set the Namespace property.

Weitere Informationen zum Verwenden von Attributen finden Sie unter Attribute .For more information about using attributes, see Attributes

Hinweis

Sie können das Wort SoapAttribute in Ihrem Code verwenden, anstatt das längere SoapAttributeAttribute.You can use the word SoapAttribute in your code instead of the longer SoapAttributeAttribute.
