Keterangan

Agar deserialisasi berhasil, posisi saat ini dalam aliran harus berada di awal grafik objek.

Penting

Berlaku untuk

Deserialize(Stream, HeaderHandler)

Mendeserialisasi aliran ke dalam grafik objek dengan header apa pun dalam aliran tersebut yang ditangani oleh .HeaderHandler

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

Parameter

serializationStream: Stream

Aliran yang berisi data yang akan dideserialisasi.

handler: HeaderHandler

Delegasikan untuk menangani header apa pun yang ditemukan di aliran. Bisa jadi null.

Mengembalikan

Object

Objek atas grafik yang dideserialisasi (root).

Penerapan

Deserialize(Stream, HeaderHandler)

Pengecualian

ArgumentNullException

serializationStreamadalah null.

SerializationException

serializationStream mendukung pencarian, dan panjangnya adalah 0.

Keterangan

Header hanya digunakan untuk aplikasi jarak jauh tertentu. Parameter HeaderHandler adalah salah satu dari dua cara untuk mengembalikan header dari aliran dalam format SOAP Remote Procedure Call (RPC). Cara lain adalah dengan menggunakan TopObject properti .

Agar deserialisasi berhasil, posisi saat ini dalam aliran harus berada di awal grafik objek.

Objek TimeSpan diserialisasikan sesuai dengan standar ISO 8601: 1998 bagian 5.5.3.2.1 "Alternatif".
