Appendix R Streams

The .NET Framework provides several classes that treat data as a stream—an ordered series of bytes. These classes are not difficult to use, but they are similar enough to be confusing. This appendix summarizes the stream classes and describes their properties and their methods. See Chapter 18, “Streams,” for more information on streams.

Stream Class Summary

The following table lists the .NET Framework stream classes.

Class	Purpose
BinaryReader, BinaryWriter	Read and write data from an underlying stream using routines that manage specific data types (such as ReadDouble and ReadUInt16).
BufferedStream	Adds buffering to another stream type. This sometimes improves performance on relatively slow underlying devices.
CryptoStream	Applies a cryptographic transformation to its data.
FileStream	Represents a file as a stream. Usually, you can use a helper class such as BinaryReader or TextWriter to make working with a FileStream easier.
MemoryStream	Lets you read and write stream data in memory. This is useful when you need a stream but don’t want to read or write a file.
NetworkStream	Sends and receives data across a network connection.
Stream	A generic stream class. This is an abstract class, so you cannot create one directly. Instead, you must instantiate one of its subclasses.
StreamReader, StreamWriter	These classes inherit from TextReader and TextWriter. They provide methods for reading and writing text into an underlying stream, usually a FileStream.
