Parameter

iocb: IOCompletionCallback

Delegasi IOCompletionCallback yang mewakili metode panggilan balik yang dipanggil ketika operasi I/O asinkron selesai.

Mengembalikan

NativeOverlapped*

Penunjuk yang tidak dikelola ke NativeOverlapped struktur.

Atribut: CLSCompliantAttribute ObsoleteAttribute SecurityCriticalAttribute

Pengecualian

InvalidOperationException

Saat ini Overlapped telah dikemas.

Keterangan

Pointer yang tidak dikelola yang dikembalikan oleh metode ini dapat diteruskan ke sistem operasi dalam operasi I/O yang tumpang tindih. Struktur NativeOverlapped diperbaiki dalam memori fisik sampai Unpack dipanggil.

Important

Pemanggil bertanggung jawab untuk menyematkan buffer. Namun, jika domain aplikasi dibongkar, handel ke buffer yang disematkan dihancurkan dan buffer dirilis, meninggalkan operasi I/O untuk menulis ke alamat yang dibebaskan. Untuk alasan ini, lebih baik menggunakan Pack(IOCompletionCallback, Object) metode kelebihan beban, di mana runtime menyematkan buffer.

Berlaku untuk

Pack(IOCompletionCallback, Object)

Parameter

iocb: IOCompletionCallback

Delegasi IOCompletionCallback yang mewakili metode panggilan balik yang dipanggil ketika operasi I/O asinkron selesai.

userData: Object

Objek atau array objek yang mewakili buffer input atau output untuk operasi. Setiap objek mewakili buffer, misalnya array byte.

Mengembalikan

NativeOverlapped*

Penunjuk yang tidak dikelola ke NativeOverlapped struktur.

Atribut: CLSCompliantAttribute ComVisibleAttribute SecurityCriticalAttribute

Pengecualian

InvalidOperationException

Saat ini Overlapped telah dikemas.

Keterangan

Buffer atau buffer yang ditentukan di userData harus sama dengan yang diteruskan ke fungsi sistem operasi yang tidak dikelola yang melakukan I/O asinkron.

Note

Runtime menyematkan buffer atau buffer yang ditentukan selama userData durasi operasi I/O. Jika domain aplikasi dibongkar, runtime menjaga memori tetap disematkan hingga operasi I/O selesai.
