arraylist property "get/set" value

[Pierson C]

A quick easy one!

I have a custom user control that has an ArrayList property. I create an
instance of the user control, assign all of the properties, but when I add
the control to the page, my ArrayList variable has gone out of scope (all int
and string properties still exist).

It must be where an ArrayList is treated like an Object, but there are
shortcuts in place for strings and ints....

Any thoughts?
In control:
--------------------------------------
public ArrayList List
{
set
{list = value;}
}
---------------------------------------
In Page:
---------------------------------------
Select cntrl;
cntrl = (Select)this.Page.LoadControl("~/Controls/Select.ascx");
cntrl.Title = "My Control";
cntrl.List = keyItems;
/*GOES OUT OF SCOPE RIGHT AFTER ASSIGNING!!!

/*Add Control to Form*/
HtmlForm form = (HtmlForm)this.FindControl("Form1");
form.Controls.Add(cntrl);
---------------------------------------
Any thoughts?
