Question

我一直在自学C#，为了自学，我一直在开发一个简单的游戏，其中有两个超级英雄使用gif动画作为动作来互相攻击。

我一直在试图解决一个问题，使gif循环一次，然后将最后一张图像设置为静止图像。

我创建了一个提取帧并返回Image数组的函数。

    /// <summary>
    /// A method that extracts the frames of a gif.
    /// </summary>
    /// <param name="original_gif">The original gif</param>
    /// <returns>Array of image frames</returns>
    private Image[] GetFrames(Image original_gif)
    {
        ///Get the frame count of the gif
        int number_of_frames = original_gif.GetFrameCount(FrameDimension.Time);

        ///New image array to store the extracted frames
        Image[] frames = new Image[number_of_frames];

        ///Loop through the gif and store each frame in the frames array
        for (int index = 0; index < number_of_frames; index++)
        {
            original_gif.SelectActiveFrame(FrameDimension.Time, index);
            frames[index] = ((Image)original_gif.Clone());
        }

        return frames;
    }

当我尝试遍历Image数组并将最后一个元素设置为picturebox

    /// <summary>
    /// A method that changes the hero picture box to standing
    /// </summary>
    private void SetStandingImage()
    {
        ///Extract images from the gif
        Image[] frames = GetFrames(Properties.Resources.captain_motion_standing);

        ///Loop through the frames displaying each image once
        for (int index = 0; index < frames.Length; index++)
        {
           ///Set the current image to the hero picture box
            hero_picture_box.Image = frames[index];
        }
        ///Set the last frame of the gif as the hero picture box
        hero_picture_box.Image = frames[frames.Length - 1];
    }

Image中的picturebox未设置为数组的最后一帧。 picturebox继续显示循环的gif动画。

即使我注释掉循环并将刚刚的图像设置为picturebox，它也会显示正在循环的gif。

您将如何从gif中提取图像并将最后一个图像设置为picturebox？

如何在C＃中将提取的gif图像设置为图片框？
