高手帮忙啊~~~~Socket和TcpListener在接收数据时,为什么总接收不完??

Question

问题如题,下面是用Socket和TcpListener接收数据的代码,2个都接收不完,唯一的区别就是Socket比TcpListener接收数据要多一些.(局域网内没问题,在公网上才会出现).请帮忙解答下.先谢谢了!(最后20分了,没分了)//TcpListener
int bytes = 0;
byte[] byteMessage = new byte[2048];
TcpClient client = null;
NetworkStream stream = null;
TcpListener server = new TcpListener(iep);
server.Start(500);
while (true)
{
    StringBuilder sb = new StringBuilder();
    try
    {
        client = server.AcceptTcpClient();
        stream = client.GetStream();
        do
        {
            bytes = stream.Read(byteMessage, 0, byteMessage.Length);
            sb.Append(System.Text.Encoding.UTF32.GetString(byteMessage, 0, bytes));
         } while (stream.DataAvailable);
     }
     catch (SocketException ex)
     {
         Console.WriteLine(ex.ErrorCode);
     }
     finally 
     {
          if (stream != null)
              stream.Close();
          if (client != null)
              client.Close();
      }
}//Socket
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.Bind(iep);
socket.Listen(5000);
byte[] byteMessage = new byte[1024];
Socket socket1 = null;
while (true)
{
    StringBuilder sb = new StringBuilder();
    try
    {
        int bytes = 0;
        socket1 = socket.Accept();
        do
        {
            bytes = socket1.Receive(byteMessage, byteMessage.Length, 0);
            sb.Append(Encoding.UTF32.GetString(byteMessage, 0, bytes));
         } while (bytes > 0);
         socket1.Shutdown(SocketShutdown.Both);
         socket1.Close();
     }
     catch (SocketException ex)
     {
         Console.WriteLine(ex.ErrorCode);
      }
}

Answer 1

设置
socket.Blocking = true;

Answer 2

循环用的好像不对:给个小例子
        private void down(ref NetworkStream stream)
        {
            int length = 1024;
            byte[] bye = new byte[1024];
            int tt = stream.Read(bye, 0, length);
            //下面循环读取网络流并写进文件
            while (tt > 0)
            {
                string ss = System.Text.Encoding.ASCII.GetString(bye);
                int x = ss.IndexOf("<EOF>");
                if (x != -1)
                {
                    filestream.Write(bye, 0, x);
                    filestream.Flush();
                    break;
                }
                else
                {
                    filestream.Write(bye, 0, tt);
                    filestream.Flush();
                }
                tt = stream.Read(bye, 0, length);
            }
            filestream.Close();
            stream.Close();
            this.stsLable.Text = "升级包已正确接受完毕，请注意查收!";        
            FillFileList();
        }

Answer 3

stream = client.GetStream();
        do
        {
            bytes = stream.Read(byteMessage, 0, byteMessage.Length);
            sb.Append(System.Text.Encoding.UTF32.GetString(byteMessage, 0, bytes));
         } while (stream.DataAvailable);
我给你分析一下你这个循环亚
stream = client.GetStream();//这时候stream第一次被读取过来，如果这次有数据的话
那么
while (stream.DataAvailable)永远成立，你的程序陷入了死循环，你肯定一辈子读不完了
