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 exceptions that the .NET framework provides, like NullReferenceException and ArgumentOutOfRangeException. Application exceptions are custom exceptions that you can define in your application.

Can you give me examples of system exceptions?

Sure! Some common system exceptions include: 1. NullReferenceException - occurs when you try to access a member on a type that is null. 2. IndexOutOfRangeException - thrown when an index is outside the bounds of an array. 3. DivideByZeroException - occurs when you attempt to divide by zero.

What about application exceptions? How do I create one?

Application exceptions are user-defined exceptions. You can create one by inheriting from the Exception class. For example:

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

How do I handle exceptions in C#?

You can handle exceptions using try-catch blocks. Wrap the code that may throw an exception in a try block, and catch the exception in the catch block. For example:

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