Dieser Konstruktor legt die Eigenschaften des BinaryFormatter -Objekts wie folgt fest:This constructor sets the properties of the BinaryFormatter object as follows:

EigenschaftentypProperty Type BedingungCondition
SurrogateSelector null
Context Ein StreamingContext mit einem Wert, der angibt, dass serialisierte Daten an einen beliebigen anderen Kontext übertragen oder von diesem empfangen werden können.A StreamingContext with a value that indicates that serialized data can be transmitted to or received from any of the other contexts. (StreamingContextStates.All)(StreamingContextStates.All)

BinaryFormatter(ISurrogateSelector, StreamingContext) BinaryFormatter(ISurrogateSelector, StreamingContext) BinaryFormatter(ISurrogateSelector, StreamingContext) BinaryFormatter(ISurrogateSelector, StreamingContext)

Initialisiert eine neue Instanz der BinaryFormatter-Klasse mit einer angegebenen Surrogatauswahl und angegebenem Streamingkontext.Initializes a new instance of the BinaryFormatter class with a given surrogate selector and streaming context.

public:
 BinaryFormatter(System::Runtime::Serialization::ISurrogateSelector ^ selector, System::Runtime::Serialization::StreamingContext context);
public BinaryFormatter (System.Runtime.Serialization.ISurrogateSelector selector, System.Runtime.Serialization.StreamingContext context);

Public Sub New (selector As ISurrogateSelector, context As StreamingContext)

Parameter

selector
ISurrogateSelector ISurrogateSelector ISurrogateSelector ISurrogateSelector

Der zu verwendende ISurrogateSelector.The ISurrogateSelector to use. Kann null sein.Can be null.

context
StreamingContext StreamingContext StreamingContext StreamingContext

Die Quelle und das Ziel für die serialisierten Daten.The source and destination for the serialized data.

Hinweise

Initialisiert ein neues BinaryFormatter -Objekt für die Serialisierung oder Deserialisierung von- StreamObjekten aus dem angegebenen.Initializes a new BinaryFormatter for serialization or deserialization of objects 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.
