Begins an asynchronous write operation. Consider using WriteAsync(Byte[], Int32, Int32, CancellationToken) instead.

- arraybuffer
- Byte[]
The buffer containing data to write to the current stream.
- offset
- Int32
The zero-based byte offset in array at which to begin copying bytes to the current stream.
- numBytescount
- Int32
The maximum number of bytes to write.
- callbackuserCallback
- AsyncCallback
The method to be called when the asynchronous write operation is completed.
- statestateObject
- Object
A user-provided object that distinguishes this particular asynchronous write request from other requests.
Returns
An object that references the asynchronous write.
Exceptions
array length minus offset is less than numBytes.
array is null.
offset or numBytes is negative.
The stream does not support writing.
The stream is closed.
An I/O error occurred.
