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(0, 400);  
            this.axWindowsMediaPlayer1.Name = "axWindowsMediaPlayer1";  
            this.axWindowsMediaPlayer1.Size = new System.Drawing.Size(800, 500);  
            this.axWindowsMediaPlayer1.TabIndex = 2;  
            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 == 1)  
            {  
                //停顿2秒钟再重新播放  
                System.Threading.Thread.Sleep(2000);  
        //重新播放  
                axWindowsMediaPlayer1.Ctlcontrols.play();  
            }  
        }  
    }
