我尝试在同一个 axmediaplayer 中播放 2 个视频。我的理论是这样的：主要电影将一直播放到计时器事件触发。然后将播放新电影并保存最后一个电影位置，完成第二个电影后，最后一个将从上一个电影位置继续。

但是在完成第二部电影后，我的axmediplayer无法工作并且不会继续第一部电影......

我在网上搜索，有人说这是因为从事件处理程序调用 URL 而发生的。但我不知道如何修复它以及如何将它设置为处理程序......

                MoviePlayerCurrentPossition = Convert.ToInt32(axWindowsMediaPlayer.Ctlcontrols.currentPosition);
