Course 3358: Reading and Writing Files in the Microsoft .NET Framework 2.0

Introduction In this 2-hour course you will learn about working with the file, stream, and string handling capabilities provided to developers by the Microsoft® .NET Framework 2.0. Topics range from working with the file system and byte streams to working with strings and regular expressions. In the lab you will write code to enumerate, create and delete files. Also you will work with file compression and decompression.

This course also will help you prepare for Exam 70-536 TS: Microsoft .NET Framework 2.0—Application Development Foundation. Objectives At the end of the course, students will be able to:

• Manage the File System
  • Access files using Path, File and FileInfo
  • Access paths and directories by using Path, Directory and DirectoryInfo
  • Access drives by using DriveInfo
  • Work with FileSystemWatcher to monitor the file system
  
  
  
• Use Streams, Stream reader and Stream writer classes to access data.
  • Work with FileStream, MemoryStream, and BufferedStream
  • Read data using StreamReader, StreamWriter, and BinaryReader
  • Write data using StreamWriter and BinaryWriter
  • Compress streams using DeflateStream and GZipStream
  • Use Isolated storage
  
  
  
• Manipulate strings efficiently
  • Use StringBuilder for concatenation
  • Parse data with regular expressions
