MemoryStream.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> ^ buffer, int offset, int count, AsyncCallback ^ callback, System::Object ^ state);
public override IAsyncResult BeginWrite (byte[] buffer, int offset, int count, AsyncCallback callback, object state);
override this.BeginWrite : byte[] * int * int * AsyncCallback * obj -> IAsyncResult
Public Overrides Function BeginWrite (buffer As Byte(), offset As Integer, count As Integer, callback As AsyncCallback, state As Object) As IAsyncResult

Parameters

buffer
Byte[]

The buffer to write data from.

offset
Int32

The byte offset in buffer from which to begin writing.

count
Int32

The maximum number of bytes to write.

callback
AsyncCallback

An optional asynchronous callback, to be called when the write is complete.

state
Object

A user-provided object that distinguishes this particular asynchronous write request from other requests.

Returns

An IAsyncResult that represents the asynchronous write, which could still be pending.

Exceptions

Attempted an asynchronous write past the end of the memory stream, or a disk error occurred.

One or more of the arguments is invalid.

Methods were called after the memory stream was closed.

The current memory stream implementation does not support the write operation.

Remarks

Refer to the BeginWrite remarks for additional usage information for this method.
