Reach an object from another class then the creation class

Members of class Y are accessible from class Z only if class Z holds a reference to aclass Y instance i.e. an instance of class Y is created in class Z. An exception is if object X is declared static in class Y. I dont think you can get around this using unsafe code. But needing unsafe code to fix this type of problem likely points to a bad design - there should be a way to do what you want without it. Bill F
