authorize.net what sample code should I use to verify a customer's zip and addresses?

What sample code should I use to verify a customer's zip and addresses? I am testing the decline codes from testing guide (http://ift.tt/1GZwRZ6), when I noticed that the the charge credit card code I implemented from the sample code provided (http://ift.tt/1ORT1o1.... doesn't take in zip or address to verify.. What code am I missing? What other sample code should I be implementing to do this and be able to test the decline and other failed responses in the sandbox? ChargeCreditCard.cs is pretty much the only code I have implemented.

Thanks.
