Do I need to Flush() a FileStream when reading?

I am not sure if a buffer is also used when reading from a file, or is it only used when writing to a file.

Here's what the documentation has to say to Stream.Flush():

When overridden in a derived class, clears all buffers for this stream and causes any buffered data to be written to the underlying device.

I guess it's safe to say that flushing is not required when reading.

No. Flush() writes remaining Bytes in the write-buffer.

is a buffer is also used when reading from a file?

Yes there is a buffer for performance reasons, but there is no way to flush this buffer other than simply reading bytes form the stream until EOF is encountered.
