How can I pass ArrayList as a command Line argument to a c# program?

Question

Hi,
I have a c# program which generates an ArrayList having some set of objects in it. I want to pass this ArrayList (containing a set of objects) to another program. I thought command line argument is the best best way to achieve this... But I am  finding very difficult to do so.. Can any  one please help me in this  regard?

Thanks
