What is the purpose of try-catch-finally in C#?

The try-catch-finally construct in C# is used for exception handling. It allows you to write code that can handle errors gracefully.

Can you explain how each part works?

Sure! The 'try' block contains code that might throw an exception. The 'catch' block handles the exception, and the 'finally' block executes code regardless of whether an exception occurred.

What happens if there is no catch block?

If there is no catch block, the exception will propagate up the call stack, potentially crashing the application if unhandled.

Can you give me a code example?

Certainly! Here's a simple example:

try {
    int result = 10 / 0; // This will throw an exception
} catch (DivideByZeroException ex) {
    Console.WriteLine("Cannot divide by zero!");
} finally {
    Console.WriteLine("This will always execute.");
}
