What are the different types of exceptions in C#?

In C#, exceptions are divided into two main categories: system exceptions and application exceptions. System exceptions are predefined by the .NET framework, while application exceptions are user-defined.

Can you give me examples of system exceptions?

Sure! Some common system exceptions include NullReferenceException, IndexOutOfRangeException, and InvalidOperationException.

What about application exceptions? How do I create one?

You can create an application exception by inheriting from the ApplicationException class. For example:

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

How do I handle exceptions in C#?

You can handle exceptions using try-catch blocks. For example:

try {
    // Code that may throw an exception
} catch (MyCustomException ex) {
    // Handle the exception
} finally {
    // Code that runs regardless of an exception
}
