（C#）关于UDP协议解析收到的数据包后如何通过手动发送信息返回客户端

namespace UDP
{
    class Program
    {        private byte[] data;        public static string OX23 { get; private set; }
        public static object Private { get; private set; }        static void Main(string[] args)
        {            int recv;
            byte[] data = new byte[1024];            //得到本机IP，设置TCP端口号         
            IPEndPoint ip = new IPEndPoint(IPAddress.Parse("120.76.202.110"), 8001);
            Socket newsock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            //绑定网络地址
            newsock.Bind(ip);
            Console.WriteLine("This is a Server, host name is {0}", Dns.GetHostName());
            //等待客户机连接
            Console.WriteLine("Waiting for a client");
            //得到客户机IP
            IPEndPoint sender = new IPEndPoint(IPAddress.Any, 8900);
            EndPoint Remote = (EndPoint)(sender);
            recv = newsock.ReceiveFrom(data, ref Remote);
            Console.WriteLine("Message received from {0}: ", Remote.ToString());
            Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv));
            //客户机连接成功后，发送信息
            string welcome = "你好 ! ";
            //字符串与字节数组相互转换
            data = Encoding.ASCII.GetBytes(welcome);
            //发送信息
            newsock.SendTo(data, data.Length, SocketFlags.None, Remote);
            while (true)
            {
                data = new byte[1024];
                //发送接受信息
                recv = newsock.ReceiveFrom(data, ref Remote);
                Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv));
                newsock.SendTo(data, recv, SocketFlags.None, Remote);
                int[] s = new int[10];
                for (int i = 0; i < 10; i++)
                {
                    s[i] = data[i];
                }
                if ((s[0] == 0x48) && (s[1] == 0x46) && (s[2] == 0x55) && (s[3] == 0x54) && (s[9] == 0x23))
                {
                    Console.WriteLine("接收到正确的数据包");
                    Console.WriteLine("功能码是" + s[5]);
                    Console.WriteLine("调光等级" + s[7]);
                    Console.WriteLine("定时数为: " + s[8]);
               
                    if (s[4] == 0x00)
                    {
                        Console.WriteLine("接入1号设备");
                    }
                    else if (s[4] == 0x01)
                    {
                        Console.WriteLine("接入2号设备");
                    }
                    else
                    {
                        Console.WriteLine("接入3号设备");
                    }                    if (s[6] == 0x00)
                    {
                        Console.WriteLine("关闭开关");
                    }
                    else
                    {                     
                        Console.WriteLine("闭合开关");
                    }                }
                else
                {
                    Console.WriteLine("数据包错误");
                }
                            }
        }
    }
}        (数据包的格式为“HFUT+地址+功能码+开关+调光系数+定时数+#”返回要求开关状态与接收到的相反，调光系数变大，请问该如何改程序，谢谢）
