播放声音，等待它完成，然后做一些事情？ [英] Play a sound, wait for it to finish and then do something?

问题描述

我正在写一个 Windows窗体这应该是打三的声音文件，并在应用每个声音文件的结尾，这是改变的图像的源。

I'm writing a Windows Forms application which is supposed to play three sound files and at the end of each sound file, it's to change the source of an image.

我可以得到它使用 System.Media.SoundPlayer 来播放声音。然而，似乎在不同的线程来播放声音，在继续。

I can get it to play the sounds using System.Media.SoundPlayer. However, it seems to play the sound in a different thread, continuing on.

此的净效果是，只有最后一个播放声音和所有的图像被改变。

The net effect of this is that only the last sound is played and all the images are changed.

我试过 Thread.sleep代码，但它睡觉了整个GUI和睡眠期发生的一切在一次后，最后的声音发挥它。

I've tried Thread.Sleep, but it sleeps the whole GUI and after the sleep period everything happens at once and the last sound it played.

更新

我想PlaySynch在工作，但似乎冻结我的GUI这是不太理想。我还能怎么办？

I thought PlaySynch was working, but it seems to freeze my GUI which is less than ideal. What else can I do?
