What is the purpose of the finally block in C#?

The finally block in C# is used to execute code after a try-catch block, regardless of whether an exception was thrown.

Can you give me an example of how to use a finally block?

Sure! Here's a simple example:

try {
    // Code that may throw an exception
} catch (Exception ex) {
    // Handle exception
} finally {
    // Code that will always execute
}

Is it mandatory to use a finally block?

No, using a finally block is not mandatory. It's optional and is used when you need to ensure certain code runs regardless of exceptions.

What happens if there is no catch block?

If there is no catch block, the exception will propagate up the call stack, but the finally block will still execute if present.
