Parameters

asyncResult

The IAsyncResult object that references the pending asynchronous read request.

Returns

A int that indicates the number of bytes read from the stream, between 0 and the number of bytes specified via the Stream.BeginRead(Byte[], int, int, AsyncCallback, object) parameter count. Streams only return 0 at the end of the stream, otherwise, they block until at least 1 byte is available.

Exceptions

Type	Reason
ArgumentNullException	asyncResult is null.
ArgumentException	asyncResult did not originate from a Stream.BeginRead(Byte[], int, int, AsyncCallback, object) method on the current stream.

Remarks

Stream.EndRead(IAsyncResult) blocks until the I/O operation has completed.

Operation

As described above.
