C# 我的TCP侦听器发送数据，然后关闭。我不知道'；我不知道为什么？

上面的代码可以工作，但是由于某种原因，每当我调用它并通过调试跟踪它时，它似乎不止一次调用connectToConsole（）。我并不是在递归地调用它。我能做什么？

寻求调试帮助的问题（“为什么此代码不起作用？”）必须包括所需的行为、特定的问题或错误以及在问题本身中重现这些问题所需的最短代码。没有明确问题陈述的问题对其他读者没有用处。请参阅：。您永远不应该有一个空的catch all语句，除非在非常罕见的情况下，您100%确定自己知道自己在做什么。否则，当您的程序不工作时，您将不知道为什么，就像在本例中一样。因为您不仅抑制了可能有助于您进行故障排除的信息，而且还抑制了一开始就有问题的任何直接指示，然后您就不知所措了，因为您不知道的原因导致了其他东西不起作用。
