当我点击下一个按钮时，为什么我的程序看起来有点迟钝？ [英] Why my program looks abit laggy when i click the next button?

问题描述

This is the part of the code of my program. After i added the

SpeechSynthesizer后，我的整个程序看起来非常滞后。

单击下一步按钮会更糟。我想问题

在我的下一个按钮点击代码中，可以有人帮我解决

这个问题？

推荐答案

您好Weishen0130，

Hi Weishen0130,

一个原因是你使用了大量的if / else条件。因此，当您单击下一个按钮时，程序会检查所有条件，因此需要时间。为了获得更好的性能，我建议使用"switch / case"。而不是"if / else"。

One reason is you are using lots of if/else condition. So when your next button is clicked program checkes all the condition so it takes time. For better performance I would suggest to use "switch/ case" instead of "if/else".
