Suppose there is a simple argument function of the form

public static void Toggle(Panel p) { p.Visible = !p.Visible; }

Is it possible to set an undefined argument with no type, so that it applies an action to any given element, be it a panel, a table or a label?

The listed types have a common ancestor - Control , in System.Web.UI , System.Windows.Forms or System.Windows.Controls :

 public static void Toggle(Control p) { p.Visible = !p.Visible; }
