Hinweise

Die Serialize -Methode konvertiert die öffentlichen Felder und Lese-/Schreibeigenschaften eines Objekts in XML. Es werden keine Methoden, Indexer, private Felder oder schreibgeschützte Eigenschaften konvertiert.

Geben Sie im xmlWriter -Parameter ein Objekt an, das von der abstrakten XmlWriter Klasse abgeleitet ist. Die XmlTextWriter wird von abgeleitet XmlWriter.

Parameter

Hinweise

Der id-Parameter stellt die Basiszeichenfolge bereit, die zum Erstellen von SOAP-IDs verwendet wird. Standardmäßig sind dies "id1", "id2" usw. Wenn der Parameter jedoch auf "myBase" festgelegt ist, lauten die generierten Werte "myBaseid1", "myBaseid2" usw. Diese Funktionalität wird verwendet, um eindeutige ID-Werte für die gesamte SOAP-Nachricht zu erstellen.

Legen Sie den encodingStyle Parameter auf "http://schemas.xmlsoap.org/soap/encoding/" für SOAP-Codierung der Version 1.1; andernfalls legen Sie es auf "http://www.w3.org/2001/12/soap-encoding" für die SOAP-Codierung der Version 1.2.

Hinweise

Wenn die Serialize -Methode aufgerufen wird, werden die öffentlichen Felder und lese-/schreibeigenschaften eines Objekts in XML konvertiert. Methoden, Indexer, private Felder und schreibgeschützte Eigenschaften werden nicht serialisiert.

Verwenden Sie den stream -Parameter, um ein Objekt anzugeben, das von der abstrakten Stream Klasse abgeleitet ist, die zum Schreiben in Streams konzipiert ist. Klassen, die von der Stream -Klasse abgeleitet werden, umfassen:

• BufferedStream

• FileStream

• MemoryStream
