C#Socket通讯(2)

前言
前面已经把游戏的服务端UI搭起来来了，现在需要实现的就是编写服务端控制器与客户端的代码，实现服务端与客户端的数据传输，并将传输情况显示在服务端的UI上

服务端控制器完整代码

private static Socket socketWatch = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
        private static Thread thread;
        private static Thread r_thred;

        int bytes;
        byte[] bytestr = new byte[1024];
        bytes = socketWatch.Receive(bytestr, bytestr.Length, 0);
        recvStr += Encoding.UTF8.GetString(bytestr, 0, bytes);
        Debug.Log(recvStr);

}

我们先启动服务端进行监听

打开客户端

服务端检测到客户端上线

客户端发送消息给服务端

服务端发送消息给客户端

服务端检测到客户端下线

后言
我们现在已经完成服务端与客户端的通讯了，如果觉得本技术文章对你有帮助请给我点个赞,如果有什么不足的地方，给我提意见，让我加以改进
