c#, socket，数据在socket.close之后才发送出去

Question

c#, socket，数据理应在调用socket.send之后发出去，但实际上调用socket.close之后才发送出去。全网找了2天答应，都没解决。谢谢各位。

try
            {
                string message = "device=camera;item=ois;command=start;\\r\\n";
                byte[] bytes = Encoding.ASCII.GetBytes(message);
                Socket s = null;
                IPEndPoint hostEndPoint;
                IPAddress hostAddress = null;
                int conPort = 80;

                hostAddress = IPAddress.Parse("127.0.0.1");
                hostEndPoint = new IPEndPoint(hostAddress, 9103);

                // Creates the Socket to send data over a TCP connection.
                s = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                s.ReceiveTimeout = 1000*15;

                // Connect to the host using its IPEndPoint.
                s.Connect(hostEndPoint);

                if (!s.Connected)
                {
                    // Connection failed, try next IPaddress.
                    Console.WriteLine("Unable to connect to host");

                }
                s.Send(bytes);
                s.Close();
            } // End of the try block.

你是怎么测得这个结论的呢，中间加了sleep延时10秒吗
否则send和close之间没有任何代码，中间到底是否有阻塞你是怎么得知的呢
send只是将数据送到发送缓冲区，至于网卡什么时候将数据真正发出去，那是物理层决定的，不归应用层管
另，有发送就有接收，接收也是你写的对吗，把接收的代码放出来看看，是不是连接的时候一直在阻塞接收，要到断开之后才print
