python - *WPF* 我正在尝试以其他方法访问 TCP 套接字，但它会引发错误？

问题描述

我知道代码无法工作，但它可以阻止我说明我的问题。目前我正在尝试在 Windows GUI 和作为从属的 linux 之间建立通信。Raspi 应该控制一些步进电机。我希望他能够报告事情回来。为此，我试图保持插座打开。欢迎任何关于更好 protokoll 的想法！我打开一个到 Rasberry Pi 的 tcp 连接并通过它发送一些数据。

namespace WpfApp2
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {

        private TcpClient tcp;
        private delegate void UpdateLogCallBack(string strMessage);

        public MainWindow()
        {
            InitializeComponent();
            
        }

        private void _Write(string msg)
        {
            NetworkStream stream = tcp.GetStream();
            Byte[] data = System.Text.Encoding.ASCII.GetBytes(msg);
            stream.Write(data, 0, data.Length);


        }

        public void Button_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                tcp = new TcpClient(ip_box.Text,Convert.ToInt32(port_box.Text));
                Byte[] data = System.Text.Encoding.ASCII.GetBytes("Hallo");
                NetworkStream stream = tcp.GetStream();

                // Send the message to the connected TcpServer. 
                stream.Write(data, 0, data.Length);

                stream.Close();
                tcp.Close();


            }
            catch(Exception ex)
            {
                MessageBox.Show("Error");

            }
 
        }




        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            _Write(msg_box.Text);
        }

        private void ip_box_TextChanged(object sender, TextChangedEventArgs e)
        {

        }

     

        private void msg_box_TextChanged(object sender, TextChangedEventArgs e)
        {

        }

  

    }
}

当我按下按钮它只是崩溃。如何设置连接并按照我的意愿访问它。服务器部分的一些帮助也会有所帮助。可悲的是，我必须用 python 编写它。这是我目前的想法：
