[Winform]Media Player播放控制面板控制，单击事件截获

在项目中有这样的一个需求，需要在一台宣传机器上循环播放一段视频，并在体验的用户单击鼠标左键的时候推出全屏，可以让用户体验电脑的其它功能。

解决方案

考虑到都是windows系统的，所以采用了windows自带的播放器，Windows Media Player Com组件作为视频播放器。

如图

但是，为了更好满足需求，下面的播放控制面板需要隐藏，该怎么做呢？最后找到解决方案，设置播放器属性

windowsMediaPlay.uiMode = "none";

循环播放的代码，这里为播放器添加播放列表，代码如下：

string[] filePaths = Directory.GetFiles(_videoDirPath).Where(x => x.EndsWith(".mp4") || x.EndsWith(".wmv")).ToArray(); //添加循环播放列表 foreach (var item in filePaths) { windowsMediaPlay.currentPlaylist.appendItem(windowsMediaPlay.newMedia(item)); } //不再任务栏显示 this.ShowInTaskbar = false; this.FormClosing += VideoFrm_FormClosing; windowsMediaPlay.ClickEvent += windowsMediaPlay_ClickEvent; windowsMediaPlay.KeyUpEvent += windowsMediaPlay_KeyUpEvent; windowsMediaPlay.StatusChange += windowsMediaPlay_StatusChange; windowsMediaPlay.ErrorEvent += windowsMediaPlay_ErrorEvent; windowsMediaPlay.DoubleClickEvent += windowsMediaPlay_DoubleClickEvent; windowsMediaPlay.Ctlcontrols.play();

那么，如何在用户单击的时候，让程序最小化？

注意

在uiMode = "none"的情况下，单击会触发视频暂停的事件，，并不会退出。视频暂停，是不是视频状态变化了呢？所以在截获单击视频事件，我们完全可以在视频暂停的时候，对其进行截获。statechange事件对应的方法如下：

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) */ try { switch (windowsMediaPlay.playState) { case WMPLib.WMPPlayState.wmppsBuffering: break; case WMPLib.WMPPlayState.wmppsLast: break; case WMPLib.WMPPlayState.wmppsMediaEnded: break; case WMPLib.WMPPlayState.wmppsPaused: //单击了视频则退出 HideVideo(); break; case WMPLib.WMPPlayState.wmppsPlaying: if (!windowsMediaPlay.fullScreen) { windowsMediaPlay.fullScreen = true; } break; case WMPLib.WMPPlayState.wmppsReady: break; case WMPLib.WMPPlayState.wmppsReconnecting: break; case WMPLib.WMPPlayState.wmppsScanForward: break; case WMPLib.WMPPlayState.wmppsScanReverse: break; case WMPLib.WMPPlayState.wmppsStopped: break; case WMPLib.WMPPlayState.wmppsTransitioning: break; case WMPLib.WMPPlayState.wmppsUndefined: break; case WMPLib.WMPPlayState.wmppsWaiting: break; default: break; } } catch (Exception ex) { LogInfoData.WriteLog(new LogInfo { Dt = DateTime.Now, IsSend = false, Message = ex.Message, Op = "media_state_change_err" }); } }

关于双击全屏截获的逻辑也可以在这里处理，双击之前肯定会有一次单击，所以在这里也能进行双击最大化的处理。
