Question

Answer 1

您应该能够使用媒体播放器控件来播放媒体文件。

播放来自 http://msdn.microsoft.com/en-us/library/dd562692(VS.85).aspx 的音频的示例，您应该能够将其改编为视频:

// [ C# ]
WMPLib.WindowsMediaPlayer Player;

private void PlayFile(String url)
{
    Player = new WMPLib.WindowsMediaPlayer();
    Player.PlayStateChange += 
        new WMPLib._WMPOCXEvents_PlayStateChangeEventHandler(Player_PlayStateChange);
    Player.MediaError += 
        new WMPLib._WMPOCXEvents_MediaErrorEventHandler(Player_MediaError);
    Player.URL = url;
    Player.controls.play();
}

private void Form1_Load(object sender, System.EventArgs e)
{
    // TODO  Insert a valid path in the line below.
    PlayFile(@"c:\myaudio.wma");
}

private void Player_PlayStateChange(int NewState)
{
    if ((WMPLib.WMPPlayState)NewState == WMPLib.WMPPlayState.wmppsStopped)
    {
        this.Close();
    }
}

private void Player_MediaError(object pMediaObject)
{
    MessageBox.Show("Cannot play media file.");
    this.Close();
}
