串行端口C#，WPF中的数据接收循环

问题描述

SerialPort sp;

SerialPort sp;

 Public string[] portnames=SerialPort.GetPortNames();
        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
           foreach (string s in portnames)
            {
                comport.ItemsSource = OrderedPortNames();
            }
        }

        private void Read_Click(object sender, RoutedEventArgs e)
        {

sp = new System.IO.Ports.SerialPort(comport.Text, Convert.ToInt32(baud.Text), Parity.None, Convert.ToInt32(bitrat.Text), StopBits.One);
 sp.DataReceived += new SerialDataReceivedEventHandler(receive_data);

     private void receive_data (object sender, SerialDataReceivedEventArgs e)
        {
           string data = sp.ReadExisting();
            MyLog(data);
        }

       private void MyLog(string msg)
        {
            this.Dispatcher.Invoke(new DisplayTextDelegate(DisplayText), data);
        }

        private void DisplayText(string text)
        {
            textBox1.AppendText(text);
        }

        private void write_Click(object sender, RoutedEventArgs e)
        {
            sp.Write(textBox2.Text);
            textBox2.Text = "";
        }

        private void button2_Click(object sender, RoutedEventArgs e)
        {
            if (sp.IsOpen)
                sp.Close();
        }

这是我为Serialport数据接收和发送编写的一个小型Chat程序，我的问题是我们是否从一个COM端口向另一个COM端口发送数据，另一个COMport应该连续读取，例如，如果我在另一个COM端口发送"HELLO"阅读"HELLO"连续无限制，给出一个复选框来停止循环，请使用Threading可以提供任何帮助，我使用TextBoxes发送和接收数据.

This is a small Chat program i wrote for Serialport Data Receive and Send,my question is if we send data from one COM Port to other ,other COMport should read continuously ,for example if i send ''HELLO'' ,in other COM Port read ''HELLO'' continuous un limited,giving one checkbox to stop loop, using Threading can any one help please, i used TextBoxes for sending and receiving data .
