File IO

System.IO contains many classes for file I/O.

• BinaryReader/BinaryWriter - store and retrieve primitive data types as a binary value.
• BufferedStream - provides temporary storage for a stream of bytes that you can later commit to disk.
• Directory/DirectoryInfo- manipulate a machine's directory structure.Directoryexposes functionality with _static_ members, while theDirectoryInfo` type exposes similar functionality from a valid object reference.
• DriveInfo - detailed information about system drives.
• File
• FileInfo
• FileStream
• FileSystemWatcher - monitor modification of files in a specified directory.
• MemoryStream - random access to data stored in memory rather than in a physical file.
• Path - performs operations on string types that contain file path information in a platform independent manner.
• StreamWriter/StreamReader - store and retrieve textual information to and from a file. Does not support random access.
• StringWriter/StringReader - like StreamWriter/StreamReader, but with an underlying buffer rather than physical file.
