Using Custom Classes Between Pages

This might be an easy question, but here's goes. I usually write VB6 style code but have lately wanted to try getting into using classes for everything. For this example, lets say I have a user database and I want to add a user. On the first page, I'll take their name and password. On the second page, I'll take their billing address or something. So, if I write ONE class that takes username, password, and billing address properties, how do I use that ONE class between two pages? Currently, I would just write everything VB6 style and pass the username and password in the session state to the second page for further processing.

I can develop in VB6 style all day at a pretty frantic pace, but I really want to learn to use custom classes so I can just import the class into my next project instead of copying and changing certain elements. I've tried a test page where on the first page I'm setting a property to "testuser" and then when I try to call it on the next page it isn't there.

Anyone have any links that might help me on this one?

Thanks!

Code:

---

// In page 1
myClass lobjClass = new myClass;
// fill some properties from this page
Session["myClass"] = lobjClass;
Response.Redirect("page 2.aspx", true);
// In page 2
myClass lobjClass = Session["myClass"] as myClass;
if(null != lobjClass)
{
  // fill other properties from this page
}
