Use DiscardBufferedData to seek to a known location in the underlying stream and then begin reading from this new point, or to read the contents of a StreamReader object more than once. Because this method can cause slower performance, use it sparingly and only when you need it for a specific scenario.
Because read methods do not update the current position of the underlying stream, some class instances return more characters than are actually in the stream. One way around this problem is to use DiscardBufferedData, which causes the StreamReader object to discard its internal buffer contents.
