Begins an asynchronous read operation.

- buffer
- Byte[]
The byte array to read the data into.
- offset
- Int32
The byte offset in buffer at which to begin reading data from the stream.
- count
- Int32
The maximum number of bytes to read.
- asyncCallback
- AsyncCallback
An optional asynchronous callback, to be called when the read operation is complete.
- asyncState
- Object
A user-provided object that distinguishes this particular asynchronous read request from other requests.
Returns
An object that represents the asynchronous read operation, which could still be pending.
Exceptions
buffer is null.
offset is less than zero.
-or-
offset and count were out of bounds for the array.
-or-
count is greater than the number of elements from offset to the end of buffer.
