Change The Volume in System.Media.SoundPlayer
I am using Syste开发者_JS百科m.Media.SoundPlayer to play some wav files in my project. Is it possible to change the volume of this SoundPlayer? If there is no way to do that, how can I change the volume of my computer using C#?
From SoundPlayer adjustable volume:
Unfortunately SoundPlayer
doesn't provide an API for changing the volume. You could use the MediaPlayer
class:
using System.Windows.Media;
public class Sound
{
private MediaPlayer m_mediaPlayer;
public void Play(string filename)
{
m_mediaPlayer = new MediaPlayer();
m_mediaPlayer.Open(new Uri(filename));
m_mediaPlayer.Play();
}
// `volume` is assumed to be between 0 and 100.
public void SetVolume(int volume)
{
// MediaPlayer volume is a float value between 0 and 1.
m_mediaPlayer.Volume = volume / 100.0f;
}
}
You'll also need to add references to the PresentationCore
and WindowsBase
assemblies.
