Image控件的写法

<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">

<Image Name="img" />

</Grid>

 

 

 

通过System.Windows.Controls.Control.ManipulationStarted事件来进行调用这这个方法覆盖了System.Windows.UIElement.OnManipulationStarted（System.Windows.Input.ManipulationStartedEventArgs）。

加载网络的图片资源

protected override void OnManipulationStarted(ManipulationStartedEventArgs args)

{

Uri uri = new Uri("http://www.website.com/p_w_picpath/a.jpg");

BitmapImage bmp = new BitmapImage(uri);

img.Source = bmp;

 

args.Complete();

args.Handled = true;

base.OnManipulationStarted(args);

}

 

加载本地的图片资源

protected override void OnManipulationStarted(ManipulationStartedEventArgs args)

{

Uri uri = new Uri("../Images/Hello.png", UriKind.Relative);

StreamResourceInfo resourceInfo = Application.GetResourceStream(uri);

BitmapImage bmp = new BitmapImage();

bmp.SetSource(resourceInfo.Stream);

img.Source = bmp;

 

args.Complete();

args.Handled = true;

base.OnManipulationStarted(args);

}
