I am trying to create a method that accepts multiple types of controls - in this case Labels and Panels. The conversion does not work because IConvertible doesn't convert these Types. Any help would be so appreciated. Thanks in advance

public void LocationsLink<C>(C control)
    {
        if (control != null)
        {
            WebControl ctl = (WebControl)Convert.ChangeType(control, typeof(WebControl));
            Literal txt = new Literal();
            HyperLink lnk = new HyperLink();
            txt.Text = "If you prefer a map to the nearest facility please ";
            lnk.Text = "click here";
            lnk.NavigateUrl = "/content/Locations.aspx";
            ctl.Controls.Add(txt);
            ctl.Controls.Add(lnk);
        }
    }
