[Winform]Media Player组件全屏播放的设置

摘要

在设置程序开始运行时，让视频全屏播放时，直接设置

windowsMediaPlay.fullScreen = true;

会报错，代码如下

                windowsMediaPlay.URL = _videoPath;
                windowsMediaPlay.Ctlcontrols.play();
                windowsMediaPlay.fullScreen = true;
                windowsMediaPlay.ClickEvent += windowsMediaPlay_ClickEvent;
                windowsMediaPlay.KeyUpEvent += windowsMediaPlay_KeyUpEvent;
                windowsMediaPlay.StatusChange += windowsMediaPlay_StatusChange;

错误

抱着相信微软的心情，就在猜想，可能是位置不对，是不是必须视频在播放中才可以设置全屏？

所以在视频状态变化的事件中，这样设置

        void windowsMediaPlay_StatusChange(object sender, EventArgs e)
        {
            /*
             * 0 Undefined Windows Media Player is in an undefined state.(未定义)
               1 Stopped Playback of the current media item is stopped.(停止)
               2 Paused Playback of the current media item is paused. When a media item is paused, resuming playback begins from the same location.(停留)
               3 Playing The current media item is playing.(播放)
               4 ScanForward The current media item is fast forwarding.
               5 ScanReverse The current media item is fast rewinding.
               6 Buffering The current media item is getting additional data from the server.(转换)
               7 Waiting Connection is established, but the server is not sending data. Waiting for session to begin.(暂停)
               8 MediaEnded Media item has completed playback. (播放结束)
               9 Transitioning Preparing new media item.
               10 Ready Ready to begin playing.(准备就绪)
               11 Reconnecting Reconnecting to stream.(重新连接)
           */
            //判断视频是否已停止播放
            if ((int)windowsMediaPlay.playState == 1)
            {
                //停顿2秒钟再重新播放
                System.Threading.Thread.Sleep(1000);
                //重新播放
                windowsMediaPlay.Ctlcontrols.play();
            }
            else if ((int)windowsMediaPlay.playState == 3)
            {
                windowsMediaPlay.fullScreen = true;
            }
        }

亲测，解决问题。
