Keterangan
Agar deserialisasi berhasil, posisi saat ini dalam aliran harus berada di awal grafik objek.
Penting
Memanggil metode ini dengan data yang tidak tepercaya adalah risiko keamanan. Panggil metode ini hanya dengan data tepercaya. Untuk informasi selengkapnya, lihat Memvalidasi Semua Input.
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
Objek atas grafik yang dideserialisasi (root).
Penerapan
Pengecualian
serializationStream
adalah null
.
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".
