在C#.NET windows應用程序做視頻播放，首先要用到com組件中windows media player，當然你也可以用其它的，這裏就以windows media player爲例。

 

一、新建windows應用程序項目，添加vedioForm窗體

 

二、在com組件中找到windows media player，添加引用

 

三、代碼如下：

 

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); } //初始化播放控件的視頻文件地址 protected void InitVedioUrl() { this.axWindowsMediaPlayer1.URL = @"D:/Vedio/default.wmv"; } protected void InitEvent() { axWindowsMediaPlayer1.StatusChange += new EventHandler(axWindowsMediaPlayer1_StatusChange); } //通過控件的狀態改變，來實現視頻循環播放 protected void axWindowsMediaPlayer1_StatusChange(object sender, EventArgs e) { /* 0 Undefined Windows Media Player is in an undefined state.(未定義) 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.(轉換) 7 Waiting Connection is established, but the server is not sending data. Waiting for session to begin.(暫停) 8 MediaEnded Media item has completed playback. (播放結束) 9 Transitioning Preparing new media item. 10 Ready Ready to begin playing.(準備就緒) 11 Reconnecting Reconnecting to stream.(重新連接) */ //判斷視頻是否已停止播放 if ((int)axWindowsMediaPlayer1.playState == 1) { //停頓2秒鐘再重新播放 System.Threading.Thread.Sleep(2000); //重新播放 axWindowsMediaPlayer1.Ctlcontrols.play(); } } }  

四、OK 了，執行看效果。

 

 

以上代碼只是實現了單個視頻文件循環播放的效果，當然還可以播放一個視頻列表，這裏就不再贅敘。

 

 

以下是關於windows media player的控件詳細說明：

 

[基本屬性]

URL:string 可以指定媒體位置

enableContextMenu:Boolean 顯示/不顯示播放位置的右鍵菜單

fullScreen:boolean 全屏顯示

stretchToFit:boolean 非全屏狀態時是否伸展到最佳大小

uMode:string 播放器的模式，full：有下面的控制條; none：只有播放部份沒有控制條

playState:integer 當前控件狀態，狀態變化時會觸發OnStatusChange事件

 

[controls]

可通過WindowsMediaPlayer.controls對播放器進行控制並取得相關的一些信息：

controls.play; 播放

controls.stop; 停止

controls.pause; 暫停

controls.currentPosition：Double 當前播放進度

controls.currentPositionString：string 時間格式的字符串 “0:32″

 

[currentMedia]

可以通過WindowsMediaPlayer.currentMedia取得當前媒體的信息

currentMedia.duration Double 總長度

currentMedia.durationString 時間格式的字符串 “4:34″

 

[settings]

可以通過WindowsMediaPlayer.settings對播放器進行設置，包括音量和聲道等。

settings.volume:integer 音量 （0-100）

settings.balance:integer 聲道，通過它應該可以進行立體聲、左聲道、右聲道的控制。

 

Media Player Player.playState獲取播放狀態事件

Value State Description

0 Undefined Windows Media Player is in an undefined state.(未定義)

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.(轉換)

7 Waiting Connection is established, but the server is not sending data. Waiting for session to begin.(暫停)

8 MediaEnded Media item has completed playback. (播放結束)

9 Transitioning Preparing new media item.

10 Ready Ready to begin playing.(準備就緒)

11 Reconnecting Reconnecting to stream.(重新連接)
