asp.net WPF uses Gifbitmapdecoder to parse GIF animated files

Thanks to the powerful encapsulation of WPF, all this is done with 3 pieces of code.

For example, we often see the rabbit rubbing the face of GIF:

Program Run Result:

The code uses the Bitmapdecoder type, and for the GIF animation, you need to initialize its subclass Gifbitmapdecoder. The Bitmapdecoder frames attribute contains a series of bitmapframe. This type is the image frame used in Bitmapdecoder (and Bitmapencoder) and inherits from BitmapSource, so it is essentially a bitmap type.

Xaml:

<listbox name= "LBX" >

<ListBox.ItemsPanel>

<ItemsPanelTemplate>

<WrapPanel/>

</ItemsPanelTemplate>

</ListBox.ItemsPanel>

<ListBox.ItemTemplate>

<DataTemplate>

<image source= "{Binding}"/>

</DataTemplate>

</ListBox.ItemTemplate>

</ListBox>

Code:

            var uri = new Uri (@ "C:usersmgendesktop A.gif ");

            var gifdecoder = new Gifbitmapdecoder (URI, Bitmapcreateoptions.none, Bitmapcacheoption.default);

            LBX. ItemsSource = Gifdecoder.frames;
