Answer 1

注册全局热键及代码控件键盘输入按键

 private void btnStart_Click(object sender, EventArgs e)
        {
            RegisterHotKey(this.Handle, 469487202, 0, (UInt32)Keys.F2);//注册热键F2
            RegisterHotKey(this.Handle, 469487203, 0, (UInt32)Keys.F3);//注册热键F3
        }
        private void btnStop_Click(object sender, EventArgs e)
        {
            UnregisterHotKey(this.Handle, 469487202);//移除热键F2
            UnregisterHotKey(this.Handle, 469487203);//移除热键F3
        }
        //重写消息循环
        protected override void WndProc(ref Message m)
        {
            if (m.WParam.ToInt32() == 469487202)//F2
            {
                Thread.Sleep(300);
                SendKeys.SendWait("{2}");
                Thread.Sleep(300);
                SendKeys.SendWait("{2}");
            }
            else if (m.WParam.ToInt32() == 469487203)//F3
            {
                Thread.Sleep(300);
                SendKeys.SendWait("{3}");
                Thread.Sleep(300);
                SendKeys.SendWait("{3}");
            }
            base.WndProc(ref m);
        }
        [DllImport("user32.dll")]
        public static extern UInt32 RegisterHotKey(IntPtr hWnd, UInt32 id, UInt32 fsModifiers, UInt32 vk); //API
        [DllImport("user32.dll")]
        public static extern UInt32 UnregisterHotKey(IntPtr hWnd, UInt32 id);
