Remarques

Pour que la désérialisation réussisse, la position actuelle dans le flux doit se trouver au début du graphique d’objets.

Important

S’applique à

Deserialize(Stream, HeaderHandler)

Désérialise le flux dans un graphique d'objets, avec n'importe quel en-tête dans ce flux géré par le HeaderHandler donné.

public:
 virtual System::Object ^ Deserialize(System::IO::Stream ^ serializationStream, System::Runtime::Remoting::Messaging::HeaderHandler ^ handler);

public object Deserialize (System.IO.Stream serializationStream, System.Runtime.Remoting.Messaging.HeaderHandler handler);

abstract member Deserialize : System.IO.Stream * System.Runtime.Remoting.Messaging.HeaderHandler -> obj
override this.Deserialize : System.IO.Stream * System.Runtime.Remoting.Messaging.HeaderHandler -> obj

Public Function Deserialize (serializationStream As Stream, handler As HeaderHandler) As Object

Paramètres

serializationStream: Stream

Flux contenant les données à désérialiser.

handler: HeaderHandler

Délégué destiné à gérer n'importe quel en-tête trouvé dans le flux. Peut être null.

Retours

Object

Objet supérieur du graphique désérialisé (racine).

Implémente

Deserialize(Stream, HeaderHandler)

Exceptions

ArgumentNullException

serializationStream a la valeur null.

SerializationException

serializationStream prend en charge la recherche et sa longueur est nulle.

Remarques

Les en-têtes sont utilisés uniquement pour des applications de communication à distance spécifiques. Le HeaderHandler paramètre est l’une des deux façons de retourner des en-têtes d’un flux au format RPC (Remote Procedure Call). L’autre méthode consiste à utiliser la TopObject propriété .

Pour que la désérialisation réussisse, la position actuelle dans le flux doit se trouver au début du graphique d’objets.

Les objets TimeSpan sont sérialisés selon la norme ISO 8601 : 1998 section 5.5.3.2.1 « Alternative ».
