Question

请看下面的代码，它在我的Windows服务中不是很稳定，启动一段时间后，它会抛出错误：

例外情况如下，请帮忙吗？应用： REMSServerService.exe框架版本：v4.0.30319描述：未知异常.Info：System.Net.Sockets.SocketException Stack in System.Net.Sockets.Socket.AcceptCallback（System.Object）in System.Net.Sockets.Socket.RegisteredWaitCallback（System.Object的，布尔）在 System.Threading._ThreadPoolWaitOrTimerCallback.PerformWaitOrTimerCallback（SYSTE m.Object，布尔值）

发现错误： readsize = listensocket2.Receive（buffer_receive）;

该项目位于数据通信中心，客户端是GPRS DTU套接字客户端。

请帮助!!!

第一部分：

    protected override void OnStart(string[] args)
    {
            IPEndPoint endpoint = new IPEndPoint(RemsSocket.myip, RemsSocket.webport);
            Socket listensocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            listensocket.Bind(endpoint);
            listensocket.Listen(200);
            Thread th = new Thread(new ParameterizedThreadStart(RemsSocket.listen_send));
            th.IsBackground = true;
            th.Start(listensocket);
    }

第二部分：

    public static void listen_send(object source)
    {
        while (true)
        {
            done.Reset();
            Socket listensocket = (Socket)source;
            listensocket.BeginAccept(new AsyncCallback(acceptcallback_send), listensocket);
            done.WaitOne();
        }
    }

    public static void acceptcallback_send(IAsyncResult ar)
    {
        done.Set();
        Socket socket = (Socket)ar.AsyncState;
        Socket listensocket2 = socket.EndAccept(ar);
        byte[] buffer_validate = new byte[buffersize];
        string hostcode = "";
        byte[] buffer_send = Hex.HexStringToByteArray(validate_code);
        listensocket2.Send(buffer_send, 0, buffer_send.Length, SocketFlags.None);
        listensocket2.Receive(buffer_validate);
        int readsize = buffer_validate.Length; //listensocket2.EndReceive(ar);
        if (readsize > 0)
        {
            bool success = FirstValidate(buffer_validate, ref hostcode);
            bool validate = BLL.ExtHostBLL.CanCommunicate(hostcode); 
            if (success && validate)
            {
                LoopSendReceive(hostcode, listensocket2);
            }
        }
    }

第三部分：

    public static void LoopSendReceive(string hostcode, Socket listensocket2)
    {
        listensocket2.Blocking = true;
        byte[] buffer_receive = new byte[buffersize];
        bool validate = BLL.ExtHostBLL.CanCommunicate(hostcode); 
        while (validate)
        {
            Thread.Sleep(500);
            int readsize;
            bool success;
            IPEndPoint clientipe = (IPEndPoint)listensocket2.RemoteEndPoint;
            byte commandByte = Hex.HexStringToByteArray(command_8);
            listensocket2.Send(commandByte, 0, commandByte.Length, SocketFlags.None);
            listensocket2.ReceiveTimeout = 5000;
            int countSocketException = 0;
            readsize = listensocket2.Receive(buffer_receive);
            if (readsize != 0)
                {
                    clientipe = (IPEndPoint)listensocket2.RemoteEndPoint;
                    ClientDto client = hostList.FirstOrDefault(c => c.Ip == clientipe.Address.ToString());
                    ParseChannel.AlertStatus[] data;
                    ParseChannel channel = new ParseChannel();
                    success = channel.Parse(buffer_receive, client, out data);
                    if (!success)
                    {
                        continue;
                    }
                    SaveData(data, client);
                }
        }
    }

System.Net.Sockets.SocketException System.Net.Sockets.Socket.AcceptCallback中的Stack
