这个问题参考了我之前的问题Embedding VLC player in WInform Application in .Net Core. Core.Intialize() Giving Exception

我想运行播放器一段时间，在此期间视频应该重复播放。目前的代码看起来像这样......

Core.Initialize();
            var libvlc = new LibVLC();
            // Make VideoView control
            VideoView vv = new VideoView();
            vv.MediaPlayer = new MediaPlayer(libvlc);
            vv.Dock = DockStyle.Fill;
            // Add it to the form
            Controls.Add(vv);

            var uri = new Uri(@"C:\vid.3gp");
            // Use command line options as Options for media playback (https://wiki.videolan.org/VLC_command-line_help/)
            var media = new Media(libvlc, uri, ":input-repeat=65535");
            vv.MediaPlayer.Play(media);

            //Set fullscreen
            this.FormBorderStyle = FormBorderStyle.None;
            this.Size = Screen.PrimaryScreen.Bounds.Size;
            this.Location = Screen.PrimaryScreen.Bounds.Location;

如何在特定时间后关闭播放器。目前，即使我关闭带有播放器视频的表单，也会在后台继续播放，直到我关闭整个应用程序。

只是为了通知这个winform应用程序是在.netcore3.1中创建的。

问候。

【解决方案1】：

将 MediaPlayer 创建为类字段并调用它以在您的 WinForm 应用程序中启动/暂停/停止它。

private LibVLC _libVlc;
private MediaPlayer _mediaPlayer;
...

// Call this method in your constructor/initializer
private void StartMediaPlayer(string videoUrl)
{
    using var media = new Media(_libVlc, new Uri(videoUrl), ":input-repeat=65535");
    _mediaPlayer = new MediaPlayer(_libVlc)
    {
        Media = media
    };

    _mediaPlayer.Play();
}

// Method to stop media player
private void button1_Click(object sender, EventArgs e)
{
    _mediaPlayer.Stop();
}
