【源码开源】C#桌面应用开发：串口调试助手

c#桌面应用开发

1、环境搭建和工程创建：参照番茄定时器项目

工程创建参照

2、界面布局设计

在这里插入图片描述

3、具体功能函数

（1）端口扫描：

    private void btn_com_scan_Click(object sender, EventArgs e){//端口号扫描ReflashPortToComboBox(serialPort1, cb_select_com);}

（2）初始化界面数据设置

    private void Form1_Load(object sender, EventArgs e){//第一次加载的时候，进行端口号扫描ReflashPortToComboBox(serialPort1, cb_select_com);cb_select_com.SelectedItem = "COM1";cb_select_baudrate.SelectedItem = "115200";cb_select_data_bits.SelectedItem = "8";cb_select_check_bit.SelectedItem = "None";cb_select_stop_bit.SelectedItem = "1";btn_open_com.Enabled = true;btn_close_com.Enabled = false;//默认使用 ascii模式rbtn_recv_ascii.Checked = true;rbtn_send_ascii.Checked = true;}

(3)串口接收：

 private void ReceiveData(object sender, SerialDataReceivedEventArgs e){string content = serialPort1.ReadExisting();        //从串口中读取输入流,返回stringShowData(content);}private void ShowData(string text){string receiveText = text;//更新接收数据计数recv_cntr += (UInt32)receiveText.Length;lab_recv_cntr.Text = recv_cntr.ToString();textBox_debug.AppendText("接收到了"+ receiveText.Length.ToString()+ "个数据: "+ text+"\r\n");if (rbtn_recv_hex.Checked){//按HEX模式 展示接收到的内容 byte[] recData = System.Text.Encoding.Default.GetBytes(receiveText);// 将接受到的字符串据转化成数组；  foreach (byte str in recData){textBox_recv.AppendText(string.Format("{0:X2} ", str));}}else{//按ASCII模式 展示接收到的内容textBox_recv.AppendText(text);                   //将收到的字符串追加展示出来}}

（4）按钮事件：

private void btn_open_com_Click(object sender, EventArgs e)
{Int32 ibaudrate = Convert.ToInt32(cb_select_baudrate.SelectedItem.ToString());serialPort1.PortName = cb_select_com.SelectedItem.ToString();serialPort1.BaudRate = ibaudrate;serialPort1.Parity = (System.IO.Ports.Parity)Enum.Parse(typeof(System.IO.Ports.Parity), cb_select_check_bit.Text);serialPort1.StopBits = (System.IO.Ports.StopBits)Enum.Parse(typeof(System.IO.Ports.StopBits), cb_select_stop_bit.Text);serialPort1.DataBits = Convert.ToInt16(cb_select_data_bits.Text);//添加串口事件处理serialPort1.DataReceived += new System.IO.Ports.SerialDataReceivedEventHandler(ReceiveData);try{serialPort1.Open();btn_open_com.Enabled = false;btn_close_com.Enabled = true;}catch (Exception ex){MessageBox.Show("串口打开失败"+ex, "Error");}
