条形码扫描器-串行端口

Question

所以，我正在尝试使用我的条形码扫描器作为一个‘串行’设备，而不是一个键盘模拟器，但它没有创建com端口。我已经从手册上扫描了设置代码，将其设置为串行设备，这似乎正确配置了扫描仪（它停止将扫描代码发送到文本框\文本编辑器），但因为没有COM端口，所以我扫描条形码时无法捕获数据......

Windows在第一次插入时安装了驱动程序，但没有提供磁盘\驱动程序...不知道还有没有人经历过同样的问题.....

class Program
{
    // Create the serial port with basic settings
    private SerialPort port = new SerialPort("com1", 9600, Parity.None, 8, StopBits.One);

    [STAThread]
    static void Main(string[] args)
    {
        new Program();
    }

    private Program()
    {

        string[] ports = System.IO.Ports.SerialPort.GetPortNames();

        Console.WriteLine("Incoming Data:");

        // Attach a method to be called when there
        // is data waiting in the port's buffer
        port.DataReceived += new
          SerialDataReceivedEventHandler(port_DataReceived);

        // Begin communications
        port.Open();

        // Enter an application loop to keep this thread alive
        Application.Run();
    }

    private void port_DataReceived(object sender,
      SerialDataReceivedEventArgs e)
    {
        // Show all the incoming data in the port's buffer
        Console.WriteLine(port.ReadExisting());
    }
}

当我创建一个虚拟端口（使用第三方应用程序）时，代码运行，但我仍然无法从扫描仪获取数据....

我只是个新手，我的任务是通过串口接收条形码扫描仪的数据...我花了很多时间...我有下一个结果

using System.IO.Ports;
using System.Timers;

namespace BarCode_manager
{
    public partial class MainWindow : Window
    {

        private static SerialPort currentPort = new SerialPort();
        private static System.Timers.Timer aTimer;

        private delegate void updateDelegate(string txt);

        public MainWindow()
        {
            InitializeComponent();
            currentPort.PortName = "COM6";
            currentPort.BaudRate = 9600;
            currentPort.ReadTimeout = 1000;

            aTimer = new System.Timers.Timer(1000);
            aTimer.Elapsed += OnTimedEvent;
            aTimer.AutoReset = true;
            aTimer.Enabled = true;
        }

        private void OnTimedEvent(object sender, ElapsedEventArgs e)
        {
           if (!currentPort.IsOpen)
            {
                currentPort.Open();
                System.Threading.Thread.Sleep(100); /// for recieve all data from scaner to buffer
                currentPort.DiscardInBuffer();      /// clear buffer          
            }
            try
            {
                string strFromPort = currentPort.ReadExisting();
                lblPortData.Dispatcher.BeginInvoke(new updateDelegate(updateTextBox), strFromPort);
            }
            catch { }
        }

        private void updateTextBox(string txt)
        {
            if (txt.Length != 0)
            {
                aTimer.Stop();
                aTimer.Dispose();
                txtReceive.Text = Convert.ToString(aTimer.Enabled);
                currentPort.Close();
            }
            lblPortData.Text = txt;
            lblCount.Content = txt.Length;
            txtReceive.Text = Convert.ToString(aTimer.Enabled);
        }          

        private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
        {
            if (currentPort.IsOpen)
                currentPort.Close();
