Windows Phone 7 截取当前屏幕保存图像的代码 推荐

导入以下命名空间：

using System.Windows.Media.Imaging;
using System.IO;

using Microsoft.Xna.Framework.Media;

全部代码如下：

1 public void CaptureScreen(object sender, EventArgs e)

2 {

3 WriteableBitmap bmp = new WriteableBitmap(480, 800);

4 bmp.Render(App.Current.RootVisual, null);

5 bmp.Invalidate();

6

7 MemoryStream stream = new MemoryStream();

8 bmp.SaveJpeg(stream, bmp.PixelWidth, bmp.PixelHeight, 0, 80);

9 stream.Seek(0, SeekOrigin.Begin);

10

11 MediaLibrary library = new MediaLibrary();

12 string fileName = "ScreenShot_" + DateTime.Now.ToString("yyyy-mm-dd_hh:mm:ss");

13 library.SavePicture(fileName, stream);

14 stream.Close();

15

16

17 Dispatcher.BeginInvoke(() =>

18 {

19 PictureCollection picCollection = library.Pictures;

20 foreach (Picture item in picCollection)

21 {

22 if (item!=null)

23 {

24 BitmapImage bitmap = new BitmapImage();

25 bitmap.SetSource(item.GetImage());

26 ScreenShot.Source = bitmap;

27 PicName.Text ="图片名称 ："+ item.Name;

28 }

29

30 }

31 });

32

33

34

35 }

调用该方法后得到的效果如下：
