tcpclient 问题，求助

Question

tcp

Answer 1

断点跟,看报错时的ip和port到底都是什么

Answer 2

每次connect并发送数据之后,close了吗

Answer 3

我这么写的
using(var client=new tcpclient(ipaddress,port))
{
client.getstream().write(data);
}

Answer 4

我这么写的
using(var client=new tcpclient(ipaddress,port))
{
client.getstream().write(data);
}

Answer 5

实际上当然没那么简单，后面有read，都在using大括号里面。

Answer 6

OK.
下面是代码：
        public void Poll()
        {            
            foreach (var station in stations)
            {
                ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadPollCallback), station);
            }
            if (WaitHandle.WaitAll(doneEvent.Values.ToArray(), millsecondsTimeout, false))
            {
                int availabeThreads,aiot;
                ThreadPool.GetAvailableThreads(out availabeThreads, out aiot);
                Console.WriteLine("poll end" + index.ToString());
            }
            else
            {
                Console.WriteLine("timeout");            }
        }
        public void ThreadPollCallback(object state)
        {
            var station = state as Station;
            try
            {                
                ushort[] res = ReadWaveData(station.IP);
                lock (lockObj)
                {
                    threads[station.Id] = Thread.CurrentThread;
                    Data[station.Id] = new List<ushort>(res);
                    stationErrNum[station.Id] = 0;
                    Exceptions[station.Id] = null;
                }
            }
            catch (Exception e)
            {
                Console.WriteLine("comm thread error");
                lock (lockObj)
                {
                    threads[station.Id] = Thread.CurrentThread;
                    Exceptions[station.Id] = e;
                    stationErrNum[station.Id]++;
                    if (stationErrNum[station.Id] > 3)
                    {
                        Data[station.Id] = new List<ushort>(12); ;
                    }
                }
            }
            finally
            {
                doneEvent[station.Id].Set();
            }
        }
        public ushort[] ReadWaveData(string ipAddress)
        {
            ushort[] inputs;
            using (TcpClient client = TcpClientConnector.Connect(ipAddress, 3100, 500))
            {
                var ns = client.GetStream();
                var bw = new System.IO.BinaryWriter(ns);
                bw.Write(COMMAND_READWAVEDATA, 0, 6);
                bw.Flush();                
            }
            return inputs;
        }

Answer 7

OK.
下面是代码：
        public void Poll()
        {            
            foreach (var station in stations)
            {
                ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadPollCallback), station);
.........你忘记贴你说的“抛出异常的那一行代码”了。

Answer 8

OK.
下面是代码：
        public void Poll()
        {            
            foreach (var station in stations)
            {
                ThreadPool.QueueUserWorkItem(new WaitCallback(ThreadPollCallback), station);
.........你忘记贴你说的“抛出异常的那一行代码”了。
就是using (TcpClient client = TcpClientConnector.Connect(ipAddress, 3100, 500))这里。
