Question

我有一个按钮，其中的文字显示音乐开/关。

使用以下Console.Beep()代码：

private void button1_Click(object sender, EventArgs e)
{
    Console.Beep(659, 125);
    Console.Beep(659, 125);
    Thread.Sleep(125);
    Console.Beep(659, 125);

}

我的问题是，如果再次点击该按钮，如何指示该按钮关闭音乐，如果再按一下等等，则再将音乐重新打开。

我不习惯写完整的代码来回答一个问题，但鉴于我现在感到多么无聊，并且考虑到播放的音乐，我无法抗拒制作小型状态机的冲动。

public class Player
{
    private Thread Thread { get; set; }

    private ManualResetEventSlim Mutex { get; set; }

    public Player()
    {
        this.Mutex = new ManualResetEventSlim(false);

        this.Thread = new Thread(this.PlayThread);
        this.Thread.Start();
    }

    public void Play()
    {
        this.Mutex.Set();
    }

    public void Stop()
    {
        this.Mutex.Reset();
    }

    private void PlayThread()
    {
        foreach (var action in PlaySong())
        {
            if (!this.Mutex.IsSet)
            {
                this.Mutex.Wait();
            }

            action();
        }
    }
}

用法：实例化Player类。使用Play方法播放，停止方法停止。理想情况下，您必须在完成歌曲后处理互斥锁。

@Steve B在评论中的含义是正确的方法。您可能希望查看Timer Class，因为它很容易使用，并且可以帮助您实现他建议/您正在寻找的内容。

请参阅此主题：How do I run a simple bit of code in a new thread?

您需要将音乐作为单独的线程运行到UI本身。
