Understanding Structured Exception Handling

Abstract

In this chapter, you will learn how to handle runtime anomalies in your C# code through the use of structured exception handling (often cryptically abbreviated as SEH). Not only will you examine the C# keywords that allow you to handle such matters (try, catch, throw, finally), you will also come to understand the distinction between application-level and system-level exceptions, as well as the role of the System.Exception base class. This discussion will lead into the topic of building custom exceptions and, finally, to a quick look at the exception-centric debugging tools of Visual Studio.
