            //var uri = new Uri("img12.jpg", UriKind.Relative);相对URI
            //var uri = new Uri("pack://application:,,,/img12.jpg");//绝对URI
            var uri = new Uri("pack://application:,,,/ImageLibrary;component/img12.jpg");//访问库
            Image image = new Image();

            grid.Children.Add(image);
