套接字错误10054:错误处理问题

Eveyone。
如何解决错误代码10054？有一些关于此错误的描述。这是我通信的完整源代码。我想知道我的代码是否正常。
WSAECONNRESET10054对等方重置连接。现有连接被远程主机强制关闭。如果远程主机上的对等应用程序突然停止，主机重新启动，主机或远程网络接口被禁用，或者远程主机使用硬关闭（有关的详细信息，请参阅setsockopt远程套接字上的SO_LINGER选项）。此错误也可能导致如果由于保持活动检测到一个或多个操作正在进行时发生故障。操作正在使用WSAENETRESET失败。后续操作失败与WSAECONNRESET。

我在这里做了一篇关于异步套接字的（IMOHO）好文章，它有一些关于服务器/客户端套接字的伪代码。
文章：无法从C#中的.Net套接字正确读取数据
我认为异步示例的代码很棒。
