MemoryStream.BeginWrite(Byte[], Int32, Int32, AsyncCallback, Object) Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Begins an asynchronous write operation. (Consider using WriteAsync(Byte[], Int32, Int32, CancellationToken) instead.)

- 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.
