that support reading and writing at a
higher level of abstraction
Input
Output
Text
TextReader
StreamReader
StringReader
TextWriter
StreamWriter
StringWriter
Binary
BinaryReader
BinaryWriter
Higher level of abstraction
IO of chars and text strings - not just raw bytes
IO of values in simple types
The
Type
Reader
and

Writer
classes are not subclasses of the stream classes
They are typically built on - and
delegates to
- a
Stream
object
A Reader or Writer classes
has
a stream - it
is not
a stream
Reader and Writer classes serve as
Stream adapters
