What is the difference between try-catch and try-finally in C#?

What is the difference between try-catch and try-finally in C#?

In C#, a try-catch block is used to handle exceptions, allowing you to catch and respond to errors. A try-finally block, on the other hand, ensures that the code in the finally block runs regardless of whether an exception occurred or not.

Can you give me an example of each?

Sure! For try-catch:

try {
    // Code that may throw an exception
} catch (Exception ex) {
    // Handle the exception
}

For try-finally:

try {
    // Code that may throw an exception
} finally {
    // Code that will always run
}

When should I use try-finally instead of try-catch?

Use try-finally when you need to ensure that certain cleanup code runs, such as closing a file or releasing resources, regardless of whether an exception occurs.

Can both be used together?

Yes, you can use try-catch and try-finally together. This allows you to handle exceptions and still ensure that cleanup code runs. Here's an example:

try {
    // Code that may throw an exception
} catch (Exception ex) {
    // Handle the exception
} finally {
    // Cleanup code
}
