1.目标：实现数据的收发

2.代码演示

根据控件编程

（1）接收配置

自动清空

private void autoclear_chb_CheckedChanged(object sender, EventArgs e)
{
    if (autoclear_chb.Checked)
    {


        timer1.Start();
    }
    else
    {
        timer1.Stop();
    }
}

手动清空

 private void Manual_clear_btn_Click(object sender, EventArgs e)
 {
     reciveBuffer.Clear();
     Receive_count_tssl.Text = "";
     Receive_rtb.Text = "";
 }

十六进制

private void Receive_Hex_chb_CheckedChanged(object sender, EventArgs e)
{
    if (Receive_rtb.Text == "") return;
    if (Receive_Hex_chb.Checked)
    {
        Receive_rtb.Text = Transform.ToHexString(reciveBuffer.ToArray(), " ");
    }
    else
    {
        Receive_rtb.Text = Encoding.GetEncoding("gb2312").GetString(reciveBuffer.ToArray()).Replace("\0", "\\0");
    }
}

暂停

private void Receive_Stop_btn_Click(object sender, EventArgs e)
{
    if (isRxShow == true)
    {
        isRxShow = false;
        Receive_Stop_btn.Text = "取消暂停";
    }
    else
    {
        isRxShow = true;
        Receive_Stop_btn.Text = "暂停";
    }
}

（2）发送配置

自动发送

private void autosend_chb_CheckedChanged(object sender, EventArgs e)
{
    // 串口未打开
    if(serialPort1.IsOpen==false && autosend_chb.CheckState == CheckState.Checked)
    {
        autosend_chb.CheckState = CheckState.Unchecked;
        if(timer2!=null)
        {
            timer2.Enabled = false;
            timer2.Stop();
           // timer2 = null;
        }

        MessageBox.Show("发送失败，串口未打卡");
        return;
    }
    // 串口打开
    if (serialPort1.IsOpen == true && autosend_chb.CheckState == CheckState.Checked)
    {
        autotimer_txb.Enabled = false;
        send_btn.Enabled = false;
        int i = Convert.ToInt32(autotimer_txb.Text);
        if (i < 10 || i>60*1000)
        {
            i = 1000;
            autotimer_txb.Text = "1000";
            MessageBox.Show("自动发送数据的周期范围是10-60000毫秒", "警告");
        }
        timer2.Interval = i;
        timer2.Start();

    }
    else
    {
        send_btn.Enabled = true;
        autotimer_txb.Enabled = true;
        if(timer2!=null)
        {
            timer2.Stop();
            //timer2 = null;
        }
    }

}

手动发送

private void Manual_Send_btn_Click(object sender, EventArgs e)
{
    // 如果发送的数据不为空，则接收
    if (this.Send_rtb.Text != "" && serialPort1.IsOpen)
    {
        Console.WriteLine(Transform.ToHexString(sendBuffer.ToArray()));
        sendData();
    }
    else
    {
        MessageBox.Show("请先输入发送数据！");

    }

}

十六进制

 private void Send_Hex_chb_CheckedChanged(object sender, EventArgs e)
 {
     if(Send_rtb.Text == "") return;

     if (Send_Hex_chb.Checked == true)
     {
         Send_rtb.Text = Transform.ToHexString(sendBuffer.ToArray(), " ");
     }
     else
     {
         Send_rtb.Text = Encoding.GetEncoding("gb2312").GetString(sendBuffer.ToArray()).Replace("\0", "\\0");

     }
 }

清空发送

 private void Send_clear_btn_Click(object sender, EventArgs e)
 {
     sendBuffer.Clear();

     Send_rtb.Text = "";

     sendCount = 0;

     Receive_count_tssl.Text = "0";
 }
