This class is an extension of a TextReader and provides implementations for all its methods. CurrentEncoding returns the current encoding the StreamReader is using. If you would like to discard the buffered data (so it isn't written to a disk or other resource), call DiscardBufferedData( ).

This class is a quick way to open a file for reading. Simply call the constructor with a string containing the filename, and you can immediately begin reading from the file with methods such as Read( ), ReadLine( ), or ReadToEnd( ).
