How do I use try-catch in C#?

In C#, you can use try-catch blocks to handle exceptions. Here's a basic example:

try {
    // Code that may throw an exception
}
catch (Exception ex) {
    // Code to handle the exception
    Console.WriteLine(ex.Message);
}

What types of exceptions can I catch?

You can catch various exceptions like NullReferenceException, FormatException, and more. You can also catch general exceptions using catch (Exception ex).

Can I have multiple catch blocks?

Yes, you can have multiple catch blocks to handle different types of exceptions separately. For example:

try {
    // Code that may throw an exception
}
catch (NullReferenceException ex) {
    // Handle null reference exceptions
}
catch (FormatException ex) {
    // Handle format exceptions
}
catch (Exception ex) {
    // Handle all other exceptions
}

What about finally blocks?

A finally block can be used to execute code regardless of whether an exception was thrown or not. It's often used for cleanup tasks.
