Is it possible to have a private class?

Question

I always wonder if it is possible to have a private class? And, what would be the point of having such class?

Thanks for helping.

Yes you can - usually they are nested classes inside another type. This means you can aggregate logic into a nested class without exposing the class to anything else. Internal is also useful for nested classes.

Note however that there are some arguments against a design requiring nested classes - I tend to use them when they seem a good fit though.
