我使用SoundPlayer在
WPF程序中播放声音效果.然而,我发现当两个声音效果同时播放时,新的声音效果将取代旧声音效果(即新声音将终止旧声音并播放自身),但我想要的是继续播放旧声音效果,即使新的一个播放.
@H_301_2@SoundPlayer wowSound = new SoundPlayer("soundEffect/Wow.wav");
SoundPlayer countingSound = new SoundPlayer("soundEffect/funny.wav");
wowSound.Play(); // play like background music
countingSound.Play(); // from click to generate the sound effect
解决方法
您可以使用SoundPlayer.PlaySync()使用用户界面线程播放.wav文件,以便首先播放wowSound.然后,在wowSound完成播放后将播放countingSound
例
@H_301_2@SoundPlayer wowSound = new SoundPlayer(@"soundEffect/Wow.wav"); //Initialize a new SoundPlayer of name wowSound SoundPlayer countingSound = new SoundPlayer(@"soundEffect/funny.wav"); //Initialize a new SoundPlayer of name wowSound wowSound.PlaySync(); //Play soundEffect/Wow.wav synchronously countingSound.PlaySync(); //Play soundEffect/funny.wav synchronously注意：使用SoundPlayer不能同时播放多个声音,因为它不支持播放同步声音.如果您想一次播放两个或更多声音,System.Windows.Media.MediaPlayer将是一个更好的选择
例
@H_301_2@MediaPlayer wowSound = new MediaPlayer(); //Initialize a new instance of MediaPlayer of name wowSound wowSound.Open(new Uri(@"soundEffect/Wow.wav")); //Open the file for a media playback wowSound.Play(); //Play the media MediaPlayer countingSound = new MediaPlayer(); //Initialize a new instance of MediaPlayer of name countingSound countingSound.Open(new Uri(@"soundEffect/funny.wav")); //Open the file for a media playback countingSound.Play(); //Play the media
