Unity and winform use socket communication

Unity and winform use socket communication

Download Demo address: Unity communicates with winformsocket

1. In unity

1. Unity acts as a server to receive messages from winform. It needs to establish a server first and wait for the client to connect.

    private void SocketConnet()
    {
    
    
        //if (_ClientSocket != null)
        //    _ClientSocket.Close();
        //控制台输出侦听状态;
        Debug.Log("Waiting for a client");
        _ClientSocket = _ServerSocket.Accept();
        //获取客户端的IP和端口;
        IPEndPoint ipEndClient = _ClientSocket.RemoteEndPoint as IPEndPoint;
        //输出客户端的IP和端口
        Debug.Log("Connect with" + ipEndClient.Address.ToString() + ":" + ipEndClient.Port.ToString());
        //连接成功发送数据;
        _SendStr = "Connect succeed";
        SocketSend(_SendStr);

        Thread th = new Thread(ReceiveMsg);
        th.IsBackground = true;
        th.Start(_ClientSocket);
    }

2. Unity receives message processing

    private void ReceiveMsg(object o)
    {
    
    
        Socket client = o as Socket;
        while (true)
        {
    
    
            try
            {
    
    
                byte[] buff = new byte[1024];
                int len = client.Receive(buff);
                string msg = Encoding.UTF8.GetString(buff, 0, len);
                print("收到客户端" + client.RemoteEndPoint.ToString() + "的信息：" + msg);
                DataManager._DM.numData = msg.Split(' ');

                SocketSend(_SendStr);
            }
            catch (System.Exception ex)
            {
    
    
                SocketSend(ex.ToString());
                break;
            }
        }
    }

3. DataManager is a singleton used to store received data
   

2. In winform

1. First connect to the server

 //定义一个套接字监听  
                socketclient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);

                //获取文本框中的IP地址  
                IPAddress address = IPAddress.Parse("127.0.0.1");
                //将获取的IP地址和端口号绑定在网络节点上  
                IPEndPoint point = new IPEndPoint(address, 7000);
                try
                {
    
    
                    //客户端套接字连接到网络节点上，用的是Connect  
                    socketclient.Connect(point);
                }
                catch (Exception ex)
                {
    
    

                    return;
                }

                threadclient = new Thread(recv);
                threadclient.IsBackground = true;
                threadclient.Start();

2. send data to server

        void ClientSendMsg(string sendMsg)
        {
    
    
            //将输入的内容字符串转换为机器可以识别的字节数组     
            byte[] arrClientSendMsg = Encoding.UTF8.GetBytes(sendMsg);
            //调用客户端套接字发送字节数组     
            socketclient.Send(arrClientSendMsg);
        }
