WPF TCP 服务器侦听器在一段时间后停止侦听

Question

我创建了一个 TCP 服务器侦听器，用于侦听一些作为 TCP 客户端连接的 IOT 设备。

TCP 服务器侦听器会工作几个小时，有时会工作一整天，然后突然停止侦听。我只是用来关闭和打开 WPF 应用程序然后它开始工作相同的时间和场景继续相同。

请你看看我的代码

public partial class MainWindow : Window
{
    private TcpListener _TcpListener;
    private TcpClient _TcpClient;

    private bool _IsRun = false;
    private int countRows = 0;
    protected NetworkStream _NetStream;
    public MainWindow()
    {
        InitializeComponent();
    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        if (!string.IsNullOrEmpty(textPort.Text.Trim()))
        {
            int port = Convert.ToInt32(textPort.Text.Trim());
            _TcpListener = new TcpListener(new IPEndPoint(IPAddress.Any, port));
            _TcpListener.Start();
            _IsRun = true;
            this.btnListener.IsEnabled = false;
            Print("Listener (" + port + ") was started");
            new Task(() => {
                while (_IsRun)
                {
                    if (_TcpClient == null)
                    {
                        _TcpClient = _TcpListener.AcceptTcpClient();
                        Print("A new connected! remote:" + _TcpClient.Client.RemoteEndPoint.ToString());
                        _NetStream = _TcpClient.GetStream();
                    }
                    if (_TcpClient.Connected && _NetStream.DataAvailable)
                    {
                        byte[] buffer = null;
                        buffer = new byte[_TcpClient.Available];
                        _NetStream.Read(buffer, 0, buffer.Length);
                        string hexString = BitConverter.ToString(buffer, 0, buffer.Length).Replace("-", "");
                        string asciiString = Encoding.ASCII.GetString(buffer, 0, buffer.Length).Trim('\0');
                        Print("HEX:" + hexString + " ASCII:" + asciiString);
                        //this method will receive the Byte data
                        Analysis(buffer);
                    }
                }
            }).Start();
        }
        
    }

    private void Print(string msg)
    {
        if (countRows > 10)
        {
            this.textLog.Dispatcher.Invoke(new Action(() =>
            {
                this.textLog.Document.Blocks.Clear();
            }));

            countRows = 0;
        }
        msg = System.DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss") + "： " + msg + "\r";
        this.textLog.Dispatcher.Invoke(new Action(() =>
        {
            this.textLog.AppendText(msg);
            this.textLog.ScrollToEnd();
            countRows += 1;
        }));
    }
 }
