Answer 2

怎样实现先提示aaaa, 然后再出现bbbb.
不用怎么实现，你的btn是点了后才弹出提示框，而control也是点了后才弹出提示框，不存在谁先谁后，只有点了才触发

Answer 3

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();            foreach (Control ctrl in this.Controls)
            {                PropertyInfo propertyInfo = ctrl.GetType().GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance);
                EventHandlerList handlerList = (EventHandlerList)propertyInfo.GetValue(ctrl, null);                FieldInfo field = typeof(Control).GetField("EventClick", BindingFlags.NonPublic| BindingFlags.Static);
                Delegate d = handlerList[field.GetValue(null)];
                ctrl.Click -= (EventHandler)d;                d=Delegate.Combine(new EventHandler(this.ctrl_Click),d);
                ctrl.Click += (EventHandler)d;
            }
        }        void ctrl_Click(object sender, EventArgs e)
        {
            MessageBox.Show("aaaaa");
        }        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("bbbb");
        }
    }
