Chapter 11. Handling Exceptions

Like many object-oriented languages, C# handles errors and abnormal conditions with exceptions. An exception is an object that encapsulates information about an unusual program occurrence.

It is important to distinguish between bugs, errors, and exceptions. A bug is a programmer mistake that should be fixed before the code is shipped. Exceptions aren't a protection against bugs. Although a bug might cause an exception to be thrown, you should not rely on exceptions to handle your bugs. Rather, you should fix the bugs.
