c# - C#, visual studio 2010, how to stop a method, threads?

Question

I'm only starting learning c# (and programming in general). I'm doing a little college project that plays music based on strings. I'm using windows forms. When you press the "play" button a it starts a method with a for loop that goes through each character in the string one by one and plays the appropriate note. Works fine, but I've been trying to add a "stop" button that will stop the music as its playing, but so far when the music is playing the form is frozen and I cant hit any other buttons... Just wondering is the only way I can achieve what I want by having different threads?? (We havent really looked at threads yet!)

edit: Hey thanks all for answers!! that was very very fast! :)

Answer 1

查看BackgroundWorker 类以在后台播放音乐。它比自己操作线程简单得多。

这是一个概述：

Answer 2

只是想知道通过使用不同的线程来实现我想要的唯一方法是什么？

通常，这是发生这种情况的最常见方法。我建议看一下BackgroundWorker组件。它允许您在后台线程上运行工作（“播放音符”），但也提供取消支持。

Answer 3

您的问题的简单答案是肯定的。

您正在主线程上循环播放音乐，这意味着当代码在循环中执行时，您无法从 UI 接收任何事件。

要解决此问题，您需要在后台线程上运行音乐循环。

Answer 4

Application.DoEvents();如果您还不想使用线程，请在每次迭代后使用。Theads 是最好的解决方案，但正如我理解你的问题，当你首先学习线程时你正在等待:) 调用DoEvents()允许在调用它时处理窗口消息，所以如果你经常调用它，窗口不应该被阻塞。但请将此视为一种解决方法，而不是最佳解决方案。最好的灵魂将使用线程。
