Exception Handling in C#

Learn the basics of exception handling in C# using try, catch, and finally blocks to handle runtime errors gracefully.

What is an Exception?

An exception is a runtime error that disrupts the normal flow of a program, such as dividing by zero or accessing a null reference.

The try-catch Block

Code that might throw an error is placed inside a try block, while a matching catch block defines how to handle that specific error if it occurs.

The finally Block

A finally block contains code that always runs after the try and catch blocks, regardless of whether an exception occurred, making it ideal for cleanup tasks.

Throwing Exceptions

The throw keyword is used to raise an exception explicitly, either a built-in exception type or a custom one, when your code detects an invalid situation.
