error-handling - 我希望我的程序无需打开窗口即可访问网页，电子邮件，Facebook和Twitter

Question

我一直在尝试制作一个可以回答您的问题的VI(虚拟智能)，您可以告诉它做一些事情，例如告诉我我有多少封电子邮件，告诉我是否有人给我发送了电子邮件以及我是否询问它质疑它可以搜索一个网页，例如，如果我问它正在阅读什么，它可以搜索Wikipedia并告诉我单词阅读后的前几个单词。到目前为止，这是用于语音识别和对某些问题的答复的代码。请告诉我如何纠正一些错误，例如V.I向您问好，IDE向您说无法访问的代码。

Answer 1

该行有无法访问的代码:

EDI.Speak("Hello there");

该代码无法访问，因为您之前直接有一个break语句。我建议您在继续之前先学习一下switch语句的工作方式，因为 switch (Japaspeech)中的所有中断似乎都是错误的。尝试模仿代码将如何手动运行，以查看出现问题的地方。
