It is working fine for me. I have just dragged a new pictureBox on form and setting image property at Form_Load() event and showing GIF animated.
它对我来说很好。我刚刚在表单上拖动了一个新的图片框，并在 Form_Load() 事件中设置了图像属性并显示了 GIF 动画。
I did same as you on button click:
我在按钮点击时和你一样：
TestForms.NavBarTest newForm = new TestForms.NavBarTest();
newForm.Show();
At my Test Form:
在我的测试表中：
private void NavBarTest_Load(object sender, EventArgs e)
{
pictureBox1.Image = NavronChartControl.Properties.Resources.url;
}
Note: If your picture box is disabled then it will not animate the Gif
注意：如果您的图片框被禁用，则它不会为 Gif 设置动画

Try to implement using this link:Animated GIF in picturebox won't animateapprach.
尝试使用此链接实现：图片框中的动画 GIF 不会为apprach设置动画。

Make sure you have your image in the image property NOT THE BACKGROUND IMAGE PROPERTY. That's the mistake I made
确保您的图像位于图像属性中，而不是背景图像属性中。那是我犯的错误

The best way to achieve it is to run the animation in an async task, but accordingly, some limitations are possible to do that on windows form using:
实现它的最佳方法是在异步任务中运行动画，但相应地，在 Windows 窗体上使用以下方法可能存在一些限制：
System.Threading.Thread.Sleep(int milliseconds).
System.Threading.Thread.Sleep(int milliseconds).
My splash view is displayed with a gif (loading)
我的初始视图显示为 gif（加载中）
e.g.: In your constructor,
例如：在你的构造函数中，
public partial class MainMenu : Form
{
private SplashScreen splash = new SplashScreen();
public MainMenu ()
{
InitializeComponent();
Task.Factory.StartNew(() => {
splash.ShowDialog();
});
Thread.Sleep(2000);
}
It is imperative to put the Thread.Sleep(int)after starting a new one, don't forget that every action you did on this thread needs to be invoked, for example:
必须Thread.Sleep(int)在开始一个新的之后放置，不要忘记你在这个线程上所做的每一个动作都需要被调用，例如：
void CloseSplash()
{
Invoke(new MethodInvoker(() =>
{
splash.Close();
}));
}
Now your gif should work!
现在你的 gif 应该可以工作了！

If none of the previous answers work for you, another idea is to refresh the image tag or write it on the fly with jQuery.
In my case I needed to show an animated GIF when a button on the form was clicked. Previously it would show up but not animate. I just added a jQuery event when the button was clicked that added the image tag on-the-fly to a div through the parent tag's html() function.
如果之前的答案都不适合您，另一个想法是刷新图像标签或使用 jQuery 即时编写它。
就我而言，我需要在单击表单上的按钮时显示动画 GIF。以前它会显示但不会动画。我只是在单击按钮时添加了一个 jQuery 事件，该事件通过父标记的 html() 函数将图像标记即时添加到 div。
$('.showhidegif').html("<img src='/Content/img/angled-spinner.gif' />");
<div class="col-sm-12 showhidegif"></div>
Worth a shot especially if you're already using jquery on your page.
值得一试，特别是如果您已经在页面上使用 jquery。

I had the same issue and came across different solutions by implementing which I used to face several different issues. Finally, below is what I put some pieces from different posts together which worked for me as expected.
我遇到了同样的问题，并且通过实施我曾经遇到过几个不同的问题，遇到了不同的解决方案。最后，下面是我将来自不同帖子的一些片段放在一起，它们按预期对我有用。
private void btnCompare_Click(object sender, EventArgs e)
{
ThreadStart threadStart = new ThreadStart(Execution);
Thread thread = new Thread(threadStart);
thread.SetApartmentState(ApartmentState.STA);
thread.Start();
}
Here is the Executionmethod that also carries invoking the PictureBox control:
下面是Execution方法，它也带有调用 PictureBox 控件：
private void Execution()
{
btnCompare.Invoke((MethodInvoker)delegate { pictureBox1.Visible = true; });
Application.DoEvents();
// Your main code comes here . . .
btnCompare.Invoke((MethodInvoker)delegate { pictureBox1.Visible = false; });
}
Keep in mind, the PictureBox is invisible from Properties Windowor do below:
请记住，PictureBox 在属性窗口中是不可见的，或者执行以下操作：
private void ComparerForm_Load(object sender, EventArgs e)
{
pictureBox1.Visible = false;
}
