我想在UWP应用程序中使用GIF图片(带有动画(作为我的飞溅屏幕。但是我不知道如何实现它。我发现一些链接可以提供一些解决方案，但似乎它们不适合UWP应用程序。像这个：https://social.msdn.microsoft.com/forums/en-us/3fe32aae-84cb-47fe-a2b0-a2b0-6650ce225c/splashscreen-that-loads-loads-an-that-loads-an-an-an-an-an-animimated-gif gorum = forum = forum = forum = vssmartdevicevbcsvbcsvbcsvbcsvbcs
private void Form1_Load(object sender, EventArgs e)
{
String imgPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase.ToString()) + "\Ani.gif";
StringBuilder sb = new StringBuilder();
sb.Append("<html><body>");
sb.Append("<img src = "" + imgPath + "">");
sb.Append("</body></html>");
webBrowser1.DocumentText = sb.ToString();
}
您对UWP应用程序有可行的解决方案吗？请指教。谢谢！

通过检查朱先生给出链接，我做了一个gif飞溅屏幕，它可以正常工作。但是有新问题：在GIF显示之前，可能会有5s白屏。如何删除它？新的测试代码如下：
Package.appxmanifest：评论原始的飞溅屏幕png文件
<!--<uap:SplashScreen Image="AssetsSplashScreen.png" />-->
app.xaml.cs：
protected override void OnLaunched(LaunchActivatedEventArgs e)
{
if (e.PreviousExecutionState != ApplicationExecutionState.Running)
{
bool loadState = (e.PreviousExecutionState == ApplicationExecutionState.Terminated);
ExtendedSplash extendedSplash = new ExtendedSplash(e.SplashScreen, loadState);
Window.Current.Content = extendedSplash;
}
Window.Current.Activate();
}
