C#监听事件（窗体关闭、按键等）

1.监听窗体关闭事件（rslr_main为窗体名）

        public rslr_main()
        {
            InitializeComponent();
            this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(Form_Closing);
        }
        private void Form_Closing(object sender, FormClosingEventArgs e)
        {
            ExcelExit();
            Owner.Show();
        }

 2.按键监听

        //下一件快捷键
        private void rssm_main_KeyDown(object sender, KeyEventArgs e)
        {
            if (e.Modifiers == Keys.Control && e.KeyCode == Keys.D) //"Ctrl + D"触发
            {
                //MessageBox.Show("快捷键");
           }
        }

 要把窗体的KeyPreview设置为true才有效

还要在**.Designer.cs里边加入

            this.KeyDown += new System.Windows.Forms.KeyEventHandler(this.rssm_main_KeyDown);

 这样就可以监听到了
