Will someone show me how to reference a .dll file in my bin folder?

on reference click reight key of mouse ,add dll file, is ok!

Thanks for the help. It seemed that it is referenced now, but how do I access the classes and properties of this .dll?

Well you just declare a variable of the correct type and instantiate it. If you don't want to use the full name with its namespace add a using statement. If you tell us the names of the classes, with their namespaces, we'll show you an example.
