c sharp与python通信

最近在学unity，想在unity调用python。因此学习了使用udp来建立通信。

python发送，c sharp接收

python代码

import socket
import time

sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
serverAddressPort = ("127.0.0.1", 10086)      # 5052 定义localhost与端口，当然可以定义其他的host

count = 0
while True:
    sock.sendto(str.encode(str(count)), serverAddressPort)
    count += 1
    time.sleep(1)

c sharp代码

namespace Client
{
    class setIpAndPort
    {
        private string ip;
        private int port;
        public void setIp(string Ip)
        {
            ip = Ip;
        }
        public void setPort(int Port)
        {
            port = Port;
        }

        public setIpAndPort(string Ip, int Port)
        {
            ip = Ip;
            port = Port;
        }
        public string getIp()
        {
            return ip;
        }
        public int getPort()
        {
            return port;
        }

    }

    class Program
    {
        
        static void Main(string[] args)
        {
            // 服务端
            setIpAndPort Setting = new setIpAndPort("127.0.0.1", 10086);
            // 1、创建Udp Socket
            Socket udpServer = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            // 2、绑定ip跟端口号
            udpServer.Bind(new IPEndPoint(IPAddress.Parse(Setting.getIp()), Setting.getPort()));
            // 3、接受数据
            EndPoint remoteEndPoint = new IPEndPoint(IPAddress.Any, 0);
            byte[] data = new byte[1024];

            while (true)
            {
                int length = udpServer.ReceiveFrom(data, ref remoteEndPoint);
                // 这个方法会把数据的来源(ip:port)放在第二个参数上。
                string message = Encoding.UTF8.GetString(data, 0, length);
                Console.WriteLine("data: "+message);
                
            }
        }
    }
