What are some common exceptions in C# and how can I handle them?

Some common exceptions in C# include NullReferenceException, ArgumentException, and InvalidOperationException. You can handle them using try-catch blocks.

Can you give me an example of handling a NullReferenceException?

Sure! You can use a try-catch block like this:

try {
    // Code that may throw a NullReferenceException
}
catch (NullReferenceException ex) {
    Console.WriteLine("A null reference occurred: " + ex.Message);
}

What should I do if I encounter an ArgumentException?

For an ArgumentException, you can also use a try-catch block. It's important to validate your arguments before passing them to methods.

Are there any best practices for exception handling in C#?

Yes, some best practices include using specific exception types, avoiding empty catch blocks, and logging exceptions for debugging.
