在Wpf中使用动态GIF图像的简单方法

方法一：利用winform控件
System.Windows.Forms. PictureBox pb = new System.Windows.Forms.PictureBox()
{
Width = 200, Height = 150, SizeMode = PictureBoxSizeMode .CenterImage
};
pb.Image = System.Drawing. Image.FromFile(@"C:\Users\zez\Desktop\201203161640295.gif" );
System.Windows.Forms.Integration. WindowsFormsHost wfh = new System.Windows.Forms.Integration.WindowsFormsHost ();
wfh.Child = pb;
grid.Children.Add(wfh);

注 ：System.Windows.Forms.Integration命名空间在V3.0中，有时需要单独添加引用 C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.0\...

方法二：只能读取第一帧
BitmapImage img = new BitmapImage();
img.BeginInit();
img.UriSource = new Uri (@"C:\Users\zez\Desktop\201203161640295.gif");
img.DecodePixelWidth = 200;
img.EndInit();

Border bor = new Border() { Width=300 ,Height=200 ,HorizontalAlignment= System.Windows.HorizontalAlignment .Left};
bor.Background = new ImageBrush (img);

grid.Children.Add(bor);

方法三：使用解码器
Uri myUri = new Uri("tulipfarm.bmp", UriKind.RelativeOrAbsolute);//(第二个参数指定Uri地址)
GifBitmapDecoder decoder2 = new GifBitmapDecoder(myUri, BitmapCreateOptions.PreservePixelFormat, BitmapCacheOption.Default);
通过decoder2.Frames可以获取gif所有帧,然后存入集合，循环播放，
