c# - 打开/关闭音乐按钮 Console.Beep

标签 c# console beep

我有一个带有文本的按钮，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);

我的问题是如何让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，依此类推。

最佳答案

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，考虑到播放的音乐，我无法抑制制作一个小型状态机的冲动。 

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，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体。
