What is the try-catch-finally construct in C#?

Can you explain the try-catch-finally construct in C#?

Sure! The try-catch-finally construct in C# is used for exception handling. You place code that might throw an exception in the try block, catch exceptions in the catch block, and use the finally block for code that should run regardless of whether an exception occurred.

Can you give me an example of how to use it?

Of course! Here's a simple example:

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

What happens if there is no catch block?

If there is no catch block, the exception will propagate up the call stack, and if unhandled, it will terminate the program.

Can I have multiple catch blocks?

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