c# - WPF如何同时播放两个声音文件？

Question

我在WPF程序中使用SoundPlayer播放音效。但是，我发现当两个音效同时播放时，新的会取代旧的(即新的会终止旧的并自己播放)，但我想要的是继续播放旧的即使播放新的。

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

Answer 1

您可以使用 SoundPlayer.PlaySync()，它使用用户界面线程播放 .wav 文件，以便首先播放 wowSound .然后，countingSound会在wowSound播放完毕

后播放

示例

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:您不能使用SoundPlayer 同时播放多个声音，因为它不支持同时播放声音。如果您想同时播放两种或多种声音，System.Windows.Media.MediaPlayer 将是更好的选择

示例

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
