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

Exceptions in C# are runtime errors that disrupt the normal flow of a program. 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 should I do if I want to catch multiple exceptions?

You can catch multiple exceptions by using multiple catch blocks or a single catch block with a base exception type. For example:

try {
    // Some code that may throw exceptions
} catch (DivideByZeroException ex) {
    Console.WriteLine("Divide by zero error: " + ex.Message);
} catch (FormatException ex) {
    Console.WriteLine("Format error: " + ex.Message);
}

Is there a way to create custom exceptions?

Yes, you can create custom exceptions by inheriting from the Exception class. Here's a simple example:

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