按下按钮即可播放声音

Question

I want a sound player to play as long as a button is pressed.

Here is what I've done so far :

public partial class Form1 : Form
{
    private SoundPlayer soundPlayer;

    private void FormMain_KeyPress(object sender, KeyPressEventArgs e)        
    {
        if(e.KeyChar == 'n')
        { 
            SoundPlayer s = new SoundPlayer(@"C:\Users\darude_rig\Desktop\dayz sounboard\media\sounds\AKM.wav");
            s.PlayLooping();
        }
    }
}

Where is the problem and how can I fix it?

You might try initializing and/or looping the SoundPlayer instance in a KeyDown event, and then stopping it in a KeyUp event.

public partial class Form1 : Form
{
    private SoundPlayer soundPlayer;

    private void FormMain_KeyDown(object sender, KeyEventArgs e)        
    {
        if(e.KeyCode == Keys.N)
        { 
            if (soundPlayer == null)
                soundPlayer = new SoundPlayer(@"C:\Users\darude_rig\Desktop\dayz sounboard\media\sounds\AKM.wav");

            soundPlayer.PlayLooping();
        } 
    }

    private void FormMain_KeyUp(object sender, KeyEventArgs e)        
    { 
        if(e.KeyCode == Keys.N)
        { 
            if (soundPlayer != null)
                soundPlayer.Stop();
        }
    }
}

Remember to subscribe to the form KeyUp and KeyDown events somewhere.
