Hinweise

Die Deserialisierung ist der Prozess, bei dem ein XML-Dokument gelesen und ein Objekt erstellt wird, das stark in das XML-Schema (XSD) des Dokuments eingegeben ist.

Vor der Deserialisierung muss eine XmlSerializer mit dem Typ des Objekts erstellt werden, das deserialisiert wird.

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

• BufferedStream

• FileStream

• MemoryStream

• NetworkStream

• CryptoStream

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

Hinweis Die XmlSerializer kann Folgendes nicht deserialisieren: Arrays von ArrayList und Arrays von List<T>.
