windows media player 播放视频

一、新建windows应用程序项目，添加vedioForm窗体

二、在com组件中找到windows media player，添加引用

三、代码如下：

 public partial class VedioForm : Form
 {
         private AxWMPLib.AxWindowsMediaPlayer axWindowsMediaPlayer1;
         public VedioForm()
         {
             InitializeComponent();
             InitVedio();
         }
         private void VedioForm_Load(object sender, EventArgs e)
         {
             InitVedioUrl();
             InitEvent();
         }
     //初始化播放控件
         private void InitVedio()
         {
             this.axWindowsMediaPlayer1 = new AxWMPLib.AxWindowsMediaPlayer();
             this.axWindowsMediaPlayer1.Enabled = true;
             this.axWindowsMediaPlayer1.Location = new System.Drawing.Point(, );
             this.axWindowsMediaPlayer1.Name = "axWindowsMediaPlayer1";
             this.axWindowsMediaPlayer1.Size = new System.Drawing.Size(, );
             this.axWindowsMediaPlayer1.TabIndex = ;
             this.Controls.Add(this.axWindowsMediaPlayer1);
         }
         //初始化播放控件的视频文件地址
         protected void InitVedioUrl()
         {
             this.axWindowsMediaPlayer1.URL = @"D:/Vedio/default.wmv";
         }  

         protected void InitEvent()
         {
             axWindowsMediaPlayer1.StatusChange += new EventHandler(axWindowsMediaPlayer1_StatusChange);
         }  

         //通过控件的状态改变，来实现视频循环播放
         protected void axWindowsMediaPlayer1_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)axWindowsMediaPlayer1.playState == )
             {
                 //停顿2秒钟再重新播放
                 System.Threading.Thread.Sleep();
         //重新播放
                 axWindowsMediaPlayer1.Ctlcontrols.play();
             }
         }
     }

uMode:string 播放器的模式，full：有下面的控制条; none：只有播放部份没有控制条

playState:integer 当前控件状态，状态变化时会触发OnStatusChange事件

[controls]

可通过WindowsMediaPlayer.controls对播放器进行控制并取得相关的一些信息：
