What are constants in C# and how do I use them?

Constants in C# are immutable values that are known at compile time and do not change during the execution of a program. You define them using the const keyword.

Can you give me an example of defining a constant?

Sure! You can define a constant like this: const int MaxValue = 100;. This means MaxValue will always hold the value 100.

What happens if I try to change the value of a constant?

If you try to change the value of a constant, you'll get a compile-time error because constants cannot be modified after they are defined.

Are there any best practices for using constants?

Yes! It's best to use constants for values that are used multiple times in your code, like configuration settings or magic numbers, to improve readability and maintainability.
