EndRead

Waits for the pending asynchronous read to complete.

 Public Function EndRead(
	  ByVal AsyncResult As IAsyncResult ) As Long

Parameters

AsyncResult: [ByVal] IAsyncResult. The reference to the pending asynchronous request to finish.

Return Values

Long - The number of bytes read from the stream, between zero (0) and the number of bytes you requested. Streams return zero (0) only at the end of the stream, otherwise, they should block until at least one byte is available.

Remarks

Call EndRead to determine how many bytes were read from the stream.

EndRead can be called once on every IAsyncResult from BeginRead.

This method blocks until the I/O operation has completed.
