c# - System.Net.Sockets.SocketException 灾难

Question

在我们与业务层断开连接并通过 MVC Web API 进行通信的 Winforms 客户端应用程序中，我们收到了一个严重的错误。哪位高手能解释一下!
这是什么意思呢？

---> (Inner Exception #0) System.Net.Http.Httprequestexception: An Error Occurred While Sending The Request.
---> System.Net.Webexception: The Underlying Connection Was Closed: An Unexpected Error Occurred On A Receive.
---> System.Io.Ioexception: Unable To Read Data From The Transport Connection: An Existing Connection Was Forcibly Closed By The Remote Host.

好吧，总的来说，这个异常(exception)确实非常令人烦恼。但是你有什么期望？您正在使用网络。它经常躺下并起床。这种行为有两个主要原因:

执行代码的网络质量。

程序员在实现自己的通信协议(protocol)时所犯的错误。

如果这两个原因不存在，那么您应该使用超时实现自动连接之类的东西。此外，TCP 协议(protocol)实现内部将非常有帮助!
