C# 一些代码小结--串口操作

串口解析显示中文

private String SerialPortReadStr()
{
    try
    {
        String str = null;
        int n = serialPort1.BytesToRead;//数据接收缓存区的字接数
        byte[] buffer = new byte[n];//创建临时字节数组
        serialPort1.Read(buffer, 0, n);//从缓存区读取数据
        str = Encoding.GetEncoding("GB2312").GetString(buffer);
        if(!IsStopReadComData)
        {
            UpDateLogTextBox(str);
        }
        if (保存串口日志ToolStripMenuItem.Checked)
        {
            log.FaceLog.AppendSerialLog("[" + DateTime.Now.ToString() + "]"+str);
        }
        return str;
    }
    catch (Exception ex)
    {
        OutputMessage("Exception:" + ex.Message);
        return "error";
    }
}

搜索串口

private void User_SearchSerialPort()
{
    try
    {
        string[] ArryPort = SerialPort.GetPortNames();
        cb_ComName.Items.Clear();
        for (int i = 0; i < ArryPort.Length; i++)
        {
            cb_ComName.Items.Add(ArryPort[i]);
        }
        cb_ComName.SelectedIndex = 0;
        OutputMessage("搜索到串口："+string.Join(",", ArryPort));
    }
    catch (Exception)
    {
        MessageBox.Show("串口搜索失败
");
    }
}
