The Modern C# Challenge

By: Rod Stephens

Overview of this book

C# is a multi-paradigm programming language. The Modern C# Challenge covers with aspects of the .NET Framework such as the Task Parallel Library (TPL) and CryptoAPI. It also encourages you to explore important programming trade-offs such as time versus space or simplicity. There may be many ways to solve a problem and there is often no single right way, but some solutions are definitely better than others. This book has combined these solutions to help you solve real-world problems with C#. In addition to describing programming trade-offs, The Modern C# Challenge will help you build a useful toolkit of techniques such as value caching, statistical analysis, and geometric algorithms. By the end of this book, you will have walked through challenges in C# and explored the .NET Framework in order to develop program logic for real-world applications.

Chapter 6. Files and Directories

This chapter describes problems that work with files and directories. Some merely provide practice on working with files and the filesystem. You may find others to be a welcome addition to your programming toolkit. For example, some examples show how to search for duplicate files, load an image file without locking it, and save JPG images with different levels of compression.

Note that working with files and directories can be particularly dangerous for a program because that are many ways those operations can fail. For example, a directory might not exist, a file might be locked, a program might not have permission to read or write in a particular directory, or a disk drive may be corrupted. The examples in this chapter use try…catch blocks to protect themselves from unexpected file and directory errors but, to save space, I have not included that error handling code in the text shown here.
