Using a ref parameter in a form constructor

Question

First of all, this is my first post to this forum, so before I start I would like to thank all of you that contribute their time and expertise toward helping others!
   I am trying to figure out how to get a reference parameter to an object passed to a form class constructor and have access to it within other methods in the form class.
   I can get the access to the objects' address in the constructor method using ref and modify the original object there with no problem. What I really need to do is get the same access to the object in the other methods in the form class. Seems no matter what I do this is impossible. Pointers variables are not allowed to point to reference types correct? I must be overlooking something very obvious as this must be a very common scenario. Any help would be much appreciated.
