Windows Phone 7 截取当前屏幕保存图像的代码

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：
