Sockets 用python实现c#中的socket编程

我试图通过在c#中运行外部程序（python脚本）并以线程形式打开服务器来运行udp通信

当数据传输到Python脚本打开的端口时，服务器（c#程序）接收数据。 但是，在发送一些数据后，不会捕获任何数据包

奇怪的是，如果我通过从外部打开cmd来直接运行Python脚本，它工作得很好

proInfo.RedirectStandardInput = true;
proInfo.RedirectStandardOutput = true;

就在我让python进程在c#程序中运行时，观察到了这种奇怪的现象

我怀疑发送缓冲区是原因，但我不知道如何修复它

如果你能帮助我，我会非常感激的

这是我的测试代码！ c#udp服务器

        private void udpserverStart()
        {
            try
            {
                srv = new UdpClient(5582);
                IPEndPoint clientEP = new IPEndPoint(IPAddress.Any, 0);

                while (used)

                    byte[] dgram = srv.Receive(ref clientEP);

            finally
            {

            }

        private void hookStart()

            ProcessStartInfo proInfo = new ProcessStartInfo();
            proInfo.FileName = "python.exe";

        {
            t1 = new Thread(udpserverStart);
            t1.Start();

        private void button2_Click(object sender, EventArgs e)
        {
            used = false;
            srv.Close();
            //t1.Join();
            t1.Abort();
            current_pro.Kill();
            this.Close();
        }


        private void textBox1_TextChanged(object sender, EventArgs e)
        {

        }
    }
}

和python udp客户端

sc = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sc.setsockopt(socket.SOL_SOCKET, socket.SO_SNDBUF, 100000)

def message(message, data):
    if message['type'] == 'send':
        try:
            payload = str(message['payload']) + '\n'
            sc.sendto(payload.encode(), ('127.0.0.1', 5582))
            print(str(message['payload']) + '\n')
        except:
            print('error');
    elif message['type'] == 'error':
        try:
            print(str(message['stack']) + '\n')
        except:
            print('error');
    else:
        print("something...")

我只是尝试删除下面的重定向代码，效果很好

proInfo.RedirectStandardInput = true;
proInfo.RedirectStandardOutput = true;
