Answer 1

可以使用WndProc来做
   private const Int32 WM_SYSCOMMAND = 0x0112;
        private const Int32 SC_MAXMIZE = 61488;
        private const Int32 SC_MINMIZE = 61472;
        private const Int32 SC_Close = 61536;        protected override void WndProc(ref Message m)
        {
            if (m.Msg == WM_SYSCOMMAND)
            {
                switch (m.WParam.ToInt32())
                {
                    case SC_MAXMIZE:
                        MessageBox.Show("Max");
                        break;
                    case SC_MINMIZE:
                        MessageBox.Show("Min");
                        break;
                    case SC_Close:
                        MessageBox.Show("Close");
                        return;
                        break;
                }               
            }
            base.WndProc(ref m);
        }        

Answer 2

 private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            if (e.CloseReason == CloseReason.UserClosing)
            {
                if (MessageBox.Show("aaaa", "bbbb", MessageBoxButtons.YesNo, MessageBoxIcon.Asterisk) == DialogResult.Yes)
                    e.Cancel = false;
                else
                {
                    e.Cancel = true;
                    this.WindowState = FormWindowState.Minimized;
                }
            }
        }

Answer 3

添加notifyIcon控件。private void Form1_Resize(object sender, EventArgs e)
{
if (WindowState == FormWindowState.Minimized)
ShowInTaskbar = false;
}放到托盘里。任务栏不显示。
