Exception Handling in C# 9

Understanding and using exceptions is vital if you want to create maintainable code that responds correctly to runtime errors. This course will teach you how to handle errors in C# applications by throwing, catching, and customizing exceptions.

Missing or incorrectly implemented error handling code can lead to data corruption, unnecessary crashes, annoyed end-users, out-of-hours support calls, and hard to maintain code. In this course, Exception Handling in C# 9, you’ll gain the ability to correctly handle runtime errors in your C# applications. First, you’ll explore what exceptions are and why we use them. Next, you’ll discover how to respond to errors that occur in your applications at runtime. Finally, you’ll learn how to throw exceptions in your own code and even how to define your own custom exception classes. When you’re finished with this course, you’ll have the skills and knowledge of C# exception handling needed to handle runtime errors in your C# applications.
