What are some examples of try-catch in C#?

In C#, try-catch blocks are used to handle exceptions. Here's a simple example:

try {
    int result = 10 / 0; // This will throw a DivideByZeroException
} catch (DivideByZeroException ex) {
    Console.WriteLine("Cannot divide by zero: " + ex.Message);
}

Can you explain how the finally block works?

Certainly! The finally block is used to execute code after the try-catch blocks, regardless of whether an exception was thrown or not. Here's an example:

try {
    // Code that may throw an exception
} catch (Exception ex) {
    // Handle exception
} finally {
    // This code runs regardless of an exception
    Console.WriteLine("Cleanup code here.");
}

What happens if I don't catch an exception?

If you don't catch an exception, it will propagate up the call stack. If it reaches the top level without being handled, it will terminate the program and display an error message.

Are there best practices for using try-catch?

Yes, some best practices include:

1. Catch specific exceptions instead of general ones.
2. Avoid using exceptions for control flow.
3. Log exceptions for debugging purposes.
4. Use finally for cleanup code.
