我有一个按钮，上面写着音乐开/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);

我的问题是如何告诉按钮在再次单击时关闭音乐，然后在再次单击时重新打开音乐等等。

我不习惯编写完整的代码来回答问题，但考虑到我现在有多无聊，再加上播放的音乐，我无法抑制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 static IEnumerable<Action> PlaySong()

            if (!this.Mutex.IsSet)
            {
                this.Mutex.Wait();
            }

            action();
        }
    }
}

用法：实例化 Player 类。使用 Play 方法播放，使用 Stop 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 在评论中的内容是正确的方法。您可能想查看Timer Class，因为它很容易使用，并且会帮助您实现他的建议/您正在寻找的东西。

请参阅此线程：如何在新线程中运行一些简单的代码？

您需要将音乐作为 UI 本身的单独线程运行。
