Begins an asynchronous write operation.
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 -> IAsyncResultPublic Overrides Function BeginWrite (buffer As Byte(), offset As Integer, count As Integer, callback As AsyncCallback, state As Object) As IAsyncResultParameters
- 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
Writing data is not supported on the stream.
Remarks
Use the CanWrite property to determine whether the current instance supports writing.
