UDP发送和接收列表

Question

我刚刚开始进入C＃UDP网络，我想知道我是否可以发送和接收列表。我有来自另一个允许发送字符串的问题的代码，但我想发送一个类型List<KeyValuePair<int, String>>或SortedDictionary。这是我发送字符串的代码：

     SortedDictionary<int, String> m_highScorers = new SortedDictionary<int, String>();
     List<KeyValuePair<int, string>> newList = new List<KeyValuePair<int, string>>();

     m_highScorers.Add(1, "Fish");
     m_highScorers.Add(2, "Fish");
     m_highScorers.Add(3, "Koala");
     m_highScorers.Add(4, "Bear");
     m_highScorers.Add(5, "Lion");

     foreach (KeyValuePair<int, string> p in m_highScorers.OrderBy(key => key.Key))
     {
        newList.Add(p);
     }
     byte[] packetData = System.Text.ASCIIEncoding.ASCII.GetBytes(newList.ToString());

     string ServerIP      = "192.168.0.25";
     string IP            = ReturnIPAddress();
     int port             = 80;

     IPEndPoint ep        = new IPEndPoint(IPAddress.Parse(ServerIP), port);

     Socket client        = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
     client.SendTo(packetData, ep);
     Console.Read();
  }

  static string ReturnIPAddress()
  {
     IPHostEntry host;
     string localIP = "?";
     host           = Dns.GetHostEntry(Dns.GetHostName());

     foreach (IPAddress ip in host.AddressList)
     {
        if (ip.AddressFamily.ToString() == "InterNetwork")
        {
           localIP = ip.ToString();               
        }
     }
     return localIP;
  }

此代码适用于“ToString()”，但从其他计算机查看时，它不会显示列表内容或SortedDictionary。如果有办法使用UDP数据包发送这些结构，请告诉我。
