How do I create checked exceptions in C#?

How do I create checked exceptions in C#?

In C#, you can create checked exceptions by deriving from the Exception class. Unlike Java, C# does not have checked exceptions, but you can implement your own exception handling.

Can you show me an example of a checked exception?

Sure! Here's a simple example:

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

public void MyMethod()
{
    throw new MyCheckedException("This is a checked exception.");
}

How do I handle this exception in my code?

You can handle it using a try-catch block like this:

try
{
    MyMethod();
}
catch (MyCheckedException ex)
{
    Console.WriteLine(ex.Message);
}

Are there any best practices for creating exceptions?

Yes, it's best to provide meaningful messages, use specific exception types, and document your exceptions clearly.
