listview control used as a reference parameter - resulting ... does not contain a definition error

Question

public static void getitem(ref Form formname, ref ListView listname) { int x; x=formname.listname.LastSelectedIndex; } When compiled, yields: System.Windows.Forms.Form does not contain a definition for 'listname'. Not sure if this is a syntax issue in how I'm using the listview reference, or what exactly the problem is?

this code is invalid you can either run on the form controls and locate the listview and then do whatever you need or if you pass the listview by ref then just x=listname.LastSelectedIndex

When I'm directed to various links that cover topics these links are generally discussing concepts which are understood. But syntax is rarely shown. I've spent quite a bit of time trying to find where examples or syntax is discussed and it's really hard to find. I cannot find anywhere where someone has an example of how to use a ref listview properly. One would think it should work similar to ref form but of course it does not. Any help?
