c# - 如何捕获iTunes事件？

我已添加此代码

        iTunes.OnPlayerPlayingTrackChangedEvent += new _IiTunesEvents_OnPlayerPlayingTrackChangedEventEventHandler(iTunes_OnPlayerPlayingTrackChangedEvent);

和这段代码

private void iTunes_OnPlayerPlayingTrackChangedEvent(object iTrack)
    {
        if (iTunes.CurrentTrack != null)
        {
            if (iTunes.CurrentTrack.Artist != null & iTunes.CurrentTrack.Album != null & iTunes.CurrentTrack.Name != null)
            {
                artist = iTunes.CurrentTrack.Artist;
                album = iTunes.CurrentTrack.Album;
                title = iTunes.CurrentTrack.Name;

                if (!NowPlaying.IsBusy)
                {
                    NowPlaying.RunWorkerAsync();
                }
            }
        }
    }

到用c＃编程的我的应用，但是当歌曲更改时却无法捕获。我想念什么吗？

还有其他方法可以捕捉iTunes跟踪已更改的事件吗？

最佳答案

您实际上是在订阅错误的事件以捕获此信息。

这是一个代码片段，它将为您提供所需的内容：

        iTunesApp app = new iTunesApp();

    public Form1()
    {
        InitializeComponent();
        app.OnPlayerPlayEvent += new _IiTunesEvents_OnPlayerPlayEventEventHandler(app_OnPlayerPlayEvent);
    }

    public void app_OnPlayerPlayEvent(object iTrack)
    {
        IITTrack currentTrack = (IITTrack)iTrack;
        string trackName = currentTrack.Name;
        string artist = currentTrack.Artist;
        string album = currentTrack.Album;

    }
