"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

the ? indicates a nullable type, so in your code page is of type int that can be nullable, see :

It is shorthand for Nullable<int> which means the value of page can be an integer or null.
