Chapter 9. Basic Debugging

The debugger is your friend. There is simply no tool more powerful than a debugger for learning C# and for writing quality C# programs. Put simply, the debugger is a tool that helps you understand what is really going on when your program is running. It is the x-ray of software development, allowing you to see inside programs and diagnose potential problems.

Without a debugger, you are guessing; with a debugger, you are seeing. It is as simple as that. Whatever time you invest in learning to use your debugger is time well spent.

The debugger is also a powerful tool for understanding code written by others. By putting someone else's code into the debugger and stepping through it, you can see exactly how the methods work and what data they manipulate.

This book assumes you are working with Visual Studio 2005 (in one form or another).

The Visual Studio debugger provides a number of windows for watching and interacting with your program while it executes. Getting comfortable with the debugger can make the difference between quickly finding bugs and struggling for hours or days.
