            Action action = delegate() { button1.Text = "aaab"; };
            Func<int, int> mfa = mb => mb * 2;
            Func<int, int> mfb = mb => mb * 2 + 5;
            List<object> marry = new List<object>();
            marry.Add(action);
            marry.Add(mfa);
            marry.Add(mfb);

            ((Action)marry[0])();
            MessageBox.Show(((Func<int, int>)marry[1])(10).ToString());
            MessageBox.Show(((Func<int, int>)marry[2])(100).ToString());
