LiteNetLib UDP库使用

服务器端代码

public static NetManager server;
        private async void IniServer(int port)
        {
            EventBasedNetListener listener = new EventBasedNetListener();
            server = new NetManager(listener);
            var re = server.Start(port);

            MessageText += $"{re}";
            //订阅各个处理事件
            listener.PeerConnectedEvent += Listener_PeerConnectedEvent;
            listener.NetworkReceiveEvent += Listener_NetworkReceiveEvent;
            listener.PeerDisconnectedEvent += Listener_PeerDisconnectedEvent;
            listener.ConnectionRequestEvent += Listener_ConnectionRequestEvent;
            while (true)
            {
                server.PollEvents();
                await Task.Delay(1);
            }
        }

服务器接收客户端连接请求

private void Listener_ConnectionRequestEvent(ConnectionRequest request)
        {
            MessageText += "\r\n客户端连接："+request.RemoteEndPoint.Address+":"+request.RemoteEndPoint.Port;
            request.Accept();//接受连接请求
        }

客户端：

public static NetManager client;
        private async void IniServer(int port)
        {
            if (client!=null&&client.IsRunning)
                return;

            EventBasedNetListener listener = new EventBasedNetListener();
            client = new NetManager(listener);
            var re = client.Start(port);
            client.Connect("127.0.0.1", 5888, "key");//发送连接请求

            while (true)
            {
                client.PollEvents();
                await Task.Delay(5);
            }
        }

连接之后使用peer发送数据：

private void ButtonDisSend_Click(object sender, RoutedEventArgs e)
        {
           
            Task.Run(() =>
            {
                int i = 0;
                while (true)
                {
                    if (client.ConnectedPeerList.Count < 1) break;
                    NetDataWriter writer = new NetDataWriter();
                    writer.Put("发送了一些数据0123"+i);
                    client.ConnectedPeerList[0].Send(writer, DeliveryMethod.ReliableOrdered);
                    i++;
                    Thread.Sleep(100);
                }
            });
        }

服务器Listener_NetworkReceiveEvent事件将接收到数据。
