设定按钮的代码：
 private void button4_Click(object sender, EventArgs e)
        {
            Thread.Sleep(500);
            if (comboBox6.Text == "无 NONE")
                hexSend("FC00990F00");
            else if (comboBox6.Text == "奇 ODD")
                hexSend("FC00990F01");
            else
                hexSend("FC00990F02");
        }
读取按钮的代码：
 private void button5_Click(object sender, EventArgs e)
        {
            hexSend("FC009910");
            Thread.Sleep(500);
            if  (hexRecv() == "00")
                textBox2.Text = "无 NONE";
            else if (hexRecv() == "01")
                textBox2.Text = "奇 ODD";
            else
                textBox1.Text = "偶 EVEN";
        }


怎么把设定的值读取出来呢？这段代码怎么写？

哪个设定的值？
