RadiButtonList in for loop

Hi

I have 40 RadioButtonList in a page , Iwant to get the SelectedValue of each RadioButtonList in a for loop . I wrote like this :

for (int i = 1 ; i < 41 ; i ++)

{

    Response.Write(RadioButtonList(i).SelectedValue.ToString());

}

but I get this : 'System.Web.UI.WebControls.RadioButtonList' is a 'type' but is used like a 'variable'

 

Please help
