UDP怎样传输结构？

Question

       定义了一个结构
        struct tagMonitorMessage
        {
            public ulong m_message_length;
            char[] key;
            char m_system;
            char m_command;
            char[] monitor_content;
            char[] reserver;
        }
        
       用UDP传输这个结构的信息，应该怎样改下面的代码？
        发送端
        private void button1_Click(object sender, EventArgs e)
        {
            tagMonitorMessage mm = new tagMonitorMessage();
            mm.m_message_length = 1223112;            Socket s = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
            IPAddress broadcast = IPAddress.Parse(this.textBox2.Text.ToString());
            byte[] sendbuf = Encoding.GetEncoding("gb2312").GetBytes(this.textBox1.Text.ToString());
            IPEndPoint ep = new IPEndPoint(broadcast, 11000);
            s.SendTo(sendbuf, ep);
        }        接收端
         private void StartListener()
        {
            UdpClient listener = new UdpClient(listenPort);
            IPEndPoint groupEP = new IPEndPoint(IPAddress.Any, listenPort);
            try
            {
                while (!done)
                {
                    byte[] bytes = listener.Receive(ref groupEP);
                    string strIP;
                    strIP = "信息来源" + groupEP.Address.ToString();
                    string strInfo = Encoding.GetEncoding("gb2312").GetString(bytes, 0, bytes.Length);
                    MessageBox.Show(strInfo, strIP);
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
            }
            finally
            {
                listener.Close();
            }
        }

    [Serializable]
    public struct tagMonitorMessage
    {
        public ulong m_message_length;
        public char[] key;
        public char m_system;
        public char m_command;
        public char[] monitor_content;
        public char[] reserver;        public static byte[] Serialize(object obj)
        {

            MemoryStream stream = new MemoryStream();
            bf.Serialize(stream, obj);
            byte[] datas = stream.ToArray();
            stream.Dispose();
            return datas;
        }        public static object Deserialize(byte[] datas)
        {
            BinaryFormatter bf = new BinaryFormatter();
            MemoryStream stream = new MemoryStream(datas);
            object obj = bf.Deserialize(stream);
