问题描述

我的应用程序使用互联网时会调用一个事件.该事件更改了一个由 7 帧组成的动画 gif.如何让它只循环一次帧?

I have an event that gets called when my app uses the internet. The event changes an animated gif composed of 7 frames. How do I make it only loop through the frames only once?

        private void trafficSendingActive(object sender, trafficEventArgs e)
        {
            txImage.Image = Properties.Resources.blip;
        }

推荐答案

您可以使用 System.Drawing.ImageAnimator 来启动/停止 gif 动画

You could use the System.Drawing.ImageAnimator to start/stop the gif animation

// start
System.Drawing.ImageAnimator.Animate(txImage.Image, OnFrameChanged);

// stop
System.Drawing.ImageAnimator.StopAnimate(txImage.Image, OnFrameChanged);

private void OnFrameChanged(object sender, EventArgs e)
{
   // frame change
}
