So far, this book has covered all the basics of simple programming in C#. Before you move on to object‐oriented programming in the next part, you need to look at debugging and error handling in C# code.
Errors in code are something that will always be with you. No matter how good a programmer is, problems will always slip through, and part of being a good programmer is realizing this and being prepared to deal with it. Of course, some problems are minor and don't affect the execution of an application, such as a spelling mistake on a button, but glaring errors are also possible, including those that cause applications to fail completely (usually known as fatal errors).
