Comentarios

Para la deserialización correcta, la posición actual de la secuencia debe estar al principio del gráfico de objetos.

Importante

Se aplica a

Deserialize(Stream, HeaderHandler)

Deserializa la secuencia a un gráfico de objetos; el HeaderHandler especificado se encarga de controlar los encabezados que aparecen en la secuencia.

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

Parámetros

serializationStream: Stream

Secuencia que contiene los datos que se van a deserializar.

handler: HeaderHandler

Delegado que va a controlar los encabezados que se encuentren en la secuencia. Puede ser null.

Devoluciones

Object

Objeto superior del gráfico deserializado (raíz).

Implementaciones

Deserialize(Stream, HeaderHandler)

Excepciones

ArgumentNullException

serializationStream es null.

SerializationException

serializationStream admite operaciones de búsqueda, y su longitud es cero.

Comentarios

Los encabezados solo se usan para aplicaciones de comunicación remota específicas. El HeaderHandler parámetro es una de las dos maneras de devolver encabezados de una secuencia en formato de llamada a procedimiento remoto (RPC) SOAP. La otra manera es usar la TopObject propiedad .

Para la deserialización correcta, la posición actual de la secuencia debe estar al principio del gráfico de objetos.

Los objetos TimeSpan se serializan según el estándar "Alternativo" iso 8601: 1998, sección 5.5.3.2.1.
