Accessing object within list

Craig Davis

I have a parent object Z which contains a list of child objects. I would like to access the properties of the child objects within the list.

I wrote code to access the first object in the list. The code compiles correctly but returns a (object reference not set to instance of an object) error when I run the application.

Here is part of the code:

zparentobject= new Zclass();

childclass zchildobject = new childclass();

zchildobject=zparentobject.listz[0]; * source of error*

Help?

Thanks, I realize my mistake. I called the code before I initialized the object.
