Hinweise

In der folgenden Tabelle werden die anfänglichen Eigenschaftenwerte für eine SoapFormatter-Instanz aufgeführt.The following table shows the initial property values for an instance of SoapFormatter.

EigenschaftProperty WertValue
SurrogateSelector null
Context Ein neues StreamingContext , das initialisiert wird, um anzugeben, dass die serialisierten Daten an einen beliebigen anderen Kontext übertragen oder von diesem empfangen werden können.A new StreamingContext initialized to specify that the serialized data can be transmitted to or received from any of the other contexts

SoapFormatter(ISurrogateSelector, StreamingContext) SoapFormatter(ISurrogateSelector, StreamingContext) SoapFormatter(ISurrogateSelector, StreamingContext) SoapFormatter(ISurrogateSelector, StreamingContext)

Initialisiert eine neue Instanz der SoapFormatter-Klasse mit den angegebenen ISurrogateSelector und dem angegebenen StreamingContext.Initializes a new instance of the SoapFormatter class with the specified ISurrogateSelector and StreamingContext.

public:
 SoapFormatter(System::Runtime::Serialization::ISurrogateSelector ^ selector, System::Runtime::Serialization::StreamingContext context);
public SoapFormatter (System.Runtime.Serialization.ISurrogateSelector selector, System.Runtime.Serialization.StreamingContext context);
new System.Runtime.Serialization.Formatters.Soap.SoapFormatter : System.Runtime.Serialization.ISurrogateSelector * System.Runtime.Serialization.StreamingContext -> System.Runtime.Serialization.Formatters.Soap.SoapFormatter
Public Sub New (selector As ISurrogateSelector, context As StreamingContext)

Parameter

selector
ISurrogateSelector ISurrogateSelector ISurrogateSelector ISurrogateSelector

Der ISurrogateSelector, der mit der neuen Instanz von SoapFormatter verwendet werden soll.The ISurrogateSelector to use with the new instance of SoapFormatter. Kann null sein.Can be null.

context
StreamingContext StreamingContext StreamingContext StreamingContext

Der StreamingContext, der die Quelle und das Ziel der Serialisierung enthält.The StreamingContext that holds the source and destination of the serialization. Wenn der context-Parameter null ist, wird der Context standardmäßig auf CrossMachine festgelegt.If the context parameter is null, then the Context defaults to CrossMachine.

Hinweise

-Objekte werden in den angegebenen Streamserialisiert bzw. deserialisiert.Objects are serialized to, or deserialized from, the specified Stream.

Der Serialisierungs-oder Deserialisierungsprozess ISurrogateSelector verwendet den angegebenen, um nach Surrogates zu suchen, die für die zu deserialisierenden Objekttypen registriert sind.The serialization or deserialization process uses the specified ISurrogateSelector to search for surrogates that are registered for the object types you want to deserialize. Surrogates sind Hilfsprogramme, die Objekte spezifischer Klassen serialisieren und deserialisieren.Surrogates are helpers that serialize and deserialize objects of specific classes. Der Standard ISurrogateSelector Wert kann die Serialisierung von Objekten, die MarshalByRefObject von abgeleitet werden, für Remoting-Zwecke nicht verarbeiten.The default ISurrogateSelector cannot handle the serialization of objects that derive from the MarshalByRefObject for remoting purposes. In einer remotingsituation ersetzt das ISurrogateSelector angegebene das von MarshalByRefObject abgeleitete Objekt durch ObjRef ein-Objekt, das vom angegebenen Ersatzselektor serialisiert wird.In a remoting situation the specified ISurrogateSelector replaces the object derived from MarshalByRefObject with a ObjRef object that is serialized by the specified surrogate selector. Wenn Sie also Remote Objekte verwenden möchten, legen Sie den selector -Parameter auf eine Instanz von RemotingSurrogateSelectorfest.Therefore, if you want to use remote objects, set the selector parameter to an instance of RemotingSurrogateSelector. Wenn Sie keine Surrogates benötigen, legen Sie den selector -Parameter nullauf fest.If you do not need surrogates, set the selector parameter to be null.
