FileStream.BeginWrite(Byte[], Int32, Int32, AsyncCallback, Object) Method

Definition

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

public:
 override IAsyncResult ^ BeginWrite(cli::array <System::Byte> ^ array, int offset, int numBytes, AsyncCallback ^ userCallback, System::Object ^ stateObject);
public override IAsyncResult BeginWrite (byte[] array, int offset, int numBytes, AsyncCallback userCallback, object stateObject);
override this.BeginWrite : byte[] * int * int * AsyncCallback * obj -> IAsyncResult
Public Overrides Function BeginWrite (array As Byte(), offset As Integer, numBytes As Integer, userCallback As AsyncCallback, stateObject As Object) As IAsyncResult

Parameters

array
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.

numBytes
Int32

The maximum number of bytes to write.

callback
AsyncCallback

The method to be called when the asynchronous write operation is completed.

state
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.
