Exceptions and Class Libraries

Skillsoft issued completion badges are earned based on viewing the percentage required or receiving a passing score when assessment is required. Exceptions are errors that occur while your application is running. They may be caused by program logic, unexpected user input, or a host of other reasons. If left unhandled, your applications may behave in unexpected ways. In this course, you'll learn how to add error handling code to an application and how to use try-catch and try-catch finally blocks. You'll also learn how to catch exceptions thrown by the .NET framework, throw exceptions from your own methods, and define custom exception types. In .NET, you can share code across multiple projects by placing the code inside a class library. A class library is a collection of classes and other types compiled into a dynamic link library. In this course, you'll also learn how to create a DLL and call code in that DLL from your executable. You'll learn about assemblies and how a .NET DLL differs from a Windows DLL. You'll examine how to create and work with class libraries. This course was originally created by Global Knowledge (GK).
