Memulai operasi tulis asinkron. Pertimbangkan untuk menggunakan WriteAsync(Byte[], Int32, Int32, CancellationToken) sebagai gantinya.

Parameter
- arraybuffer
- Byte[]
Buffer yang berisi data untuk ditulis ke aliran saat ini.
- offset
- Int32
Offset byte berbasis nol untuk array
mulai menyalin byte ke aliran saat ini.
- numBytescount
- Int32
Jumlah maksimum byte yang akan ditulis.
- callbackuserCallback
- AsyncCallback
Metode yang akan dipanggil ketika operasi penulisan asinkron selesai.
- statestateObject
- Object
Objek yang disediakan pengguna yang membedakan permintaan tulis asinkron khusus ini dari permintaan lain.
Mengembalikan
Objek yang mereferensikan penulisan asinkron.
Pengecualian
array
panjang minus offset
kurang dari numBytes
.
array
adalah null
.
offset
atau numBytes
negatif.
Aliran tidak mendukung penulisan.
Aliran ditutup.
Terjadi kesalahan I/O.
