C＃计时器与Ofd文件打勾

Question

我有一个按钮，它播放的声音在单击时会加载一次。 我想设置一个计时器，使声音每3秒播放一次，但我不想每次都加载文件。 它应该只播放相同的声音。 如何使计时器工作，而不必一遍又一遍地加载声音文件？

编辑：我知道timer1_Tick的s.Play（）将无法工作...

private void button1_Click(object sender, EventArgs e)
{     
        OpenFileDialog ofd = new OpenFileDialog();
        if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            SoundPlayer s = new SoundPlayer(ofd.FileName);
            timer1.Start();
            s.Play();
        }

}

private void timer1_Tick(object sender, EventArgs e)
{
        s.Play();
}

Answer 1

将声音播放器作为类变量移出：

private SoundPlayer s;

private void button1_Click(object sender, EventArgs e)
{     
    OpenFileDialog ofd = new OpenFileDialog();
    if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
        s = new SoundPlayer(ofd.FileName);
        timer1.Start();
        s.Play();
    }

}

private void timer1_Tick(object sender, EventArgs e)
{
    s.Play();
}

Answer 2

将SoundPlayer设为private变量：

private SoundPlayer sp;
private void button1_Click(object sender, EventArgs e)
{     
        OpenFileDialog ofd = new OpenFileDialog();
        if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
        {
            sp = new SoundPlayer(ofd.FileName);
            timer1.Start();
            sp.Play();
        }

}
private void timer1_Tick(object sender, EventArgs e)
{
        sp.Play();
}

Answer 3

答案是使它成为全球性并从任何地方到达

SoundPlayer Global;
int counter;
private void button1_Click(object sender, EventArgs e)
{     
    OpenFileDialog ofd = new OpenFileDialog();
    if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
    {
        SoundPlayer s = new SoundPlayer(ofd.FileName);
        timer1.interval=1000;
        timer1.Start();          
    }
}

 private void timer1_Tick(object sender, EventArgs e)
{
    ++counter;
    if(counter%3==0) 
    Global.Play();
    //or another aspect   if (counter==3){Global.Play();counter=0}
}
