Hey there,
i need to play some sounds on KeyDown event in my wpf project.
i have already tried System.Media.SoundPlayer();
thie prolem with the soundPlayer is that when the sound plays , the program gets paused.
The sounds are of just about 0.2 sec, but it still creates a big difference. It affects the performance of the application.
and the sounds are .wav files, if needed i can convert it to mp3.
thenks. :-)

What I have tried:

I have already tried-
System.Media.SoundPlayer();

System.Media.SoundPlayer is capable of playing sounds asynchronously so it doesn't block the UI thread; use LoadAsync to load the file, LoadCompleted to get informed about the load completion, and Play to play it:

C#

SoundPlayer player = new SoundPlayer("file.wav");
player.LoadCompleted += delegate(object sender, AsyncCompletedEventArgs e) {
    player.Play();
};
player.LoadAsync();

Or, if you don't need to do anything else after the loading aside from playing, you can just call Play immediately after calling the constructor - thanks to Richard Deeming for pointing this out!

C#

SoundPlayer player = new SoundPlayer("file.wav");
player.Play();

Additionally, if you're playing the same sound multiple times (which you probably do, given that you play them on KeyDown events), it's worth to re-use the SoundPlayer objects so you don't have to create them and load the sound over and over again.
