在 X 时间内在 C# 中加载动画 GIF 图像

Question

如何在我的表单中显示动画图像，控制其大小和持续时间？

我尝试过这样的事情：

private void AnimImage()
{
    PicBox.Enabled = true;
    PicBox.Visible = true;                
    System.Threading.Thread.Sleep(5000);
    PicBox.Visible = false;
    PicBox.Enabled = false;
}

要在您的表单上显示动画图像，请执行以下操作；

1.)Drop a PictureBox on your Form.

2.)In the Properties Window of designer,change the image property so it contains the path to your image.

3.)Resize it as per your needs.

就是这样，现在尝试运行该项目，如果没有抛出异常，您将在PictureBox中看到您的图像动画。
在项目执行过程中的任何时候，如果您想更改图像，请使用以下声明；

pictureBox1.Load("Path to a new image");//Assuming you haven't renamed the PictureBox.

此外，如果您想手动完成这些工作，请继续阅读；

private void DisplayImage()
{
    PictureBox pictureBox1=new PictureBox();
    pictureBox1.Location=new Point(Use appropriate values to place the control);
    this.Controls.Add(pictureBox1);
    pictureBox1.Load("Path to a image to display");
}

当你不想显示PictureBox时，像其他用户说的那样将其visible属性设置为false，这样；

pictureBox1.Visible=false;

并使用下面的代码取回它；

pictureBox1.Visible=true;

更新 ：

要仅显示图像 5 秒钟，请执行此操作；

Drop a Timer on your Form.

Set its Interval property to 5000 Milliseconds.

Create a new Event for its Tick Event (locate Tick event in Events Window and double click it).

Next modify DisplayImage() so it looks like :

private void DisplayImage()
{
    timer1.Start();
    PictureBox pictureBox1=new PictureBox();
    pictureBox1.Location=new Point(Use appropriate values to place the control);
    this.Controls.Add(pictureBox1);
    pictureBox1.Load("Path to a image to display");
}

Next define an integer field(outside all functions) named count,like this;

private int count=0;

Now modify timer1_Tick() event so it looks like below;

private void timer1_Tick(object sender, EventArgs e)
{
    count++;
    if (count == 5)
    {
        SourcePictureBox.Image = null;
        count = 0;
    }
}

那应该可以完成工作。还有其他事情，请告诉我。
