Exception handling in C# is mainly achieved by four keywords: try, catch, throw, and finally. Later, we will talk about these keywords in detail. However, just to give you a basic idea of what is meant by those keywords, let's briefly discuss them:
- try: When you are not sure of the expected behavior of a piece of code or if there is a possibility of an exception, you should put that code in a try block. The try block will throw an exception if any exception happens inside the code for that block. If no exception occurs, the try block will act like a normal code block. The try block is actually designed to throw exceptions, which is its main task.
- catch: The catch block is executed when an exception is caught. Exceptions thrown by the try block will be handled by the following catch block. There could be multiple catch blocks for a try block....
