但当我按下按钮时，我只想停止侦听器-出于某种原因，listener.stop会杀死我的主UI表单ZNSMSServer。当我评论listener.Stop时，它起作用了，但我认为这不是正确的方式，我不理解为什么调用listener.Stop会对关闭产生影响？调用对象-在本例中为ZNSMSServer

如果有人曾经处理过这类问题，我将不胜感激。

提前感谢。

您可能需要设置newRequest=false；调用result=listener.BeginGetContextnew AsyncCallbackListenerCallback之前，listener；否则，新请求可能永远是错误的。问题是，VS的作用是什么？我能告诉你吗？您已致电StopListener-您是否遇到异常…？您好，谢谢您的回复。这个想法加上newRequest=false；其实并不坏。我猜当你看东西很多次的时候，你会看到这样的逻辑解决方案。我会尝试并分享答案。谢谢。不用担心，尽管我认为这与你看到的坠机事件无关。
