Question

//Load中的代码

        foreach (Control c in panel1.Controls)
        {
            //button在窗体上
            Button btn = c as Button;
            if (btn != null)
            {
                //座位是否已被占用
                if (data.ResultValue.FirstOrDefault(p => p.SEAT_ID == btn.AccessibleDescription)?.STATE == "N")
                {
                    btn.BackColor = System.Drawing.Color.Red;
                    btn.Enabled = false;
                    //判断位置方向
                    switch (btn.AccessibleName)
                    {
                        case "上":
                            btn.Image = Properties.Resources.座位__已占用__上;
                            break;
                        case "下":

                else if (data.ResultValue.FirstOrDefault(p => p.SEAT_ID == btn.AccessibleDescription)?.STATE == "Y")
                {
                    btn.Enabled = true;
                    btn.Click += new System.EventHandler(this.ZW_Click);
                    //判断位置方向
                    switch (btn.AccessibleName)
                    {
                        case "上":
                            btn.Image = Properties.Resources.座位__未占用__上;
                            break;
                        case "下":
                            btn.Image = Properties.Resources.座位__未占用__下;
                            break;
                        case "左":
                            btn.Image = Properties.Resources.座位__未占用__左;
                            break;
                        case "右":
                            btn.Image = Properties.Resources.座位__未占用__右;
                            break;
                        default:
                            break;
                    }
                }
            }
