Question

我需要在C＃应用程序中播放各种swf文件。

他们似乎开始玩得很好，但试图暂停它并没有影响第一次，如果我再试一次，那么白棋会就会消失。

我正在使用的代码如下。

同时倒带＆amp;前进没有效果。

任何评论或帮助将不胜感激。

namespace MyUI
{
    public partial class ABWithSWF : MyAbstractABFrm
    {
        // Keep Track of whats happening
        enum StateOfPlay {NotSet, Playing, Paused };

        private AxShockwaveFlashObjects.AxShockwaveFlash axShockwaveFlashCube = new AxShockwaveFlashObjects.AxShockwaveFlash();

        StateOfPlay playState = StateOfPlay.NotSet;

        public ABWithSWF()
        {
            InitializeComponent();
            pnlSwf.Controls.Add(axShockwaveFlashCube);
            axShockwaveFlashCube.Dock = DockStyle.Fill;
        }

        // One button that is either play or pause
        private void btnPlay_Click(object sender, EventArgs e)
        {
            // File to play
            string path = string.Format(@"{0}\graphical summary.swf", Utils.GetSWFPath());

            switch (playState)
            {
                case StateOfPlay.Paused:
                    axShockwaveFlashCube.Play();
                    btnPlay.ImageIndex = 3;
                    playState = StateOfPlay.Playing;
                    break;
                case StateOfPlay.Playing:
                    axShockwaveFlashCube.StopPlay();
                    btnPlay.ImageIndex = 4;
                    playState = StateOfPlay.Paused;
                    break;
                case StateOfPlay.NotSet:
                    axShockwaveFlashCube.LoadMovie(0, path);
                    axShockwaveFlashCube.Play();
                    btnPlay.ImageIndex = 4;
                    playState = StateOfPlay.Playing;
                    break;
            }
        }

        private void button2_Click(object sender, EventArgs e)
        {
            axShockwaveFlashCube.Rewind();
        }

        private void button3_Click(object sender, EventArgs e)
        {
            axShockwaveFlashCube.Forward();
        }
    }
}

我刚刚在c＃中开发了一个项目，将一个flash对象嵌入到WPF UserControl中，它必须嵌入一个Windows Forms UserControl才能播放它。

所以，我的经验是停止（） axShockwaveFlashObjects 的方法实际上暂停了电影而 Play（）实际上正在恢复电影（也是开始）。

以下是我在Windows窗体UserControl中用来播放，暂停，恢复和停止swf对象的代码：

    /// <summary>
    /// Starts playing the movie, or resumes
    /// it if it is paused.
    /// </summary>
    public void Play()
    {
        Stop();
        flash_control.Play();
    }

    /// <summary>
    /// Pauses the movie. To resume it, 
    /// call <see cref="Play()"/>.
    /// </summary>
    public void Pause()
    {
        flash_control.Stop();
    }

    /// <summary>
    /// Stops playing the movie
    /// </summary>
    public void Stop()
    {
        flash_control.Stop();
        flash_control.FrameNum = 0;
    }

使用AxShockwaveFlash时，为什么C＃中的SWF文件不会暂停
