If the database is on the user's machine and you are most worried about the user accessing it, then you may want to reevaluate your architecture. Is a web solution viable?

You can make it a hidden file:

File.SetAttributes(path, File.GetAttributes(path) | FileAttributes.Hidden); 

But your best bet is to not store anything confidential on the users machine, there's always ways to bust security. You could also encrypt the database, but as the commentors point out, this is also insecure.

The best solution is to limit rights in the database itself. If you use stored porcs to access data, you do not grant select/insert/update or delete rights to the user on the tables andthen they can't see them and they can only do waht the stored procs they are allowed to execute can do. Of course this won't work if you use any dynamic sql but you shouldn't be doing that anyway.
