第2章: Input/Output (I/O) (概述)

In this chapter, you will learn how to work with the input/output (I/O) system within the Microsoft .NET Framework. The basics of the I/O system include accessing files and folders in the file system, working with read and write streams, using compression streams, and using isolated storage.

Exam objectives in this chapter:

• Access files and folders by using the File System classes. (Refer System.IO namespace)

  • File class and FileInfo class

  • Directory class and DirectoryInfo class

  • DriveInfo class and DriveType enumeration

  • FileSystemInfo class and FileSystemWatcher class

  • Path class

  • ErrorEventArgs class and ErrorEventHandler delegate

  • RenamedEventArgs class and RenamedEventHandler delegate

• Manage byte streams by using Stream classes. (Refer System.IO namespace)

  • FileStream class

  • Stream class (not Reader and Writer classes because they are a separate objective)

  • MemoryStream class

  • BufferedStream class

• Manage the .NET Framework application data by using Reader and Writer classes. (Refer System.IO namespace)

  • StringReader class and StringWriter class

  • TextReader class and TextWriter class

  • StreamReader class and StreamWriter class

  • BinaryReader class and BinaryWriter class

• Compress or decompress stream information in a .NET Framework application (refer System.IO.Compression namespace) and improve the security of application data by using isolated storage. (Refer System.IO.IsolatedStorage namespace)

  • IsolatedStorageFile class

  • IsolatedStorageFileStream class

  • DeflateStream class

  • GZipStream class
