我一直在用c＃编写文件服务器/客户端应用程序，它似乎正在工作，但后来我意识到流没有被提前，客户端一直无法从服务器接收。所以我检查了wireshark，发现我的客户端正在发出TCPZeroWindow标记的数据包。有什么想法吗？感谢。

答案 0 :(得分：1)
如果您没有在客户端正确清空网络缓冲区并且TCP窗口大小因此减少到零，我已经看到了这种情况。
使用
可能会发生这种情况tcp01.Client.Receive(data04, SocketFlags.None);
可能没有充分清除缓冲区，请参阅MSDN。您希望连续呼叫接收，直到没有其他数据可用。
如果您想将一个工作示例作为比较，请参阅here。
答案 1 :(得分：0)
我使用单独的线程来执行繁重的发送/接收方法，增加缓冲区大小，增加发送之间的时间，确保碎片已打开。现在就像一个魅力。
