What are exceptions in C# and how do I handle them?

Exceptions in C# are runtime errors that disrupt the normal flow of execution. You can handle them using try-catch blocks.

Can you give me an example of a try-catch block?

Sure! 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);
}

What other types of exceptions should I be aware of?

Some common exceptions include NullReferenceException, IndexOutOfRangeException, and FileNotFoundException. Each has its own causes and handling methods.

How can I create my own custom exceptions?

You can create a custom exception by inheriting from the Exception class. Here's a quick example:

public class MyCustomException : Exception {
    public MyCustomException(string message) : base(message) {}
}
