This似乎捕捉並保存到磁盤

捕捉

// create a WriteableBitmap 

WriteableBitmap bitmap = new WriteableBitmap(

    (int)this.LayoutRoot.ActualWidth, 

    (int)this.LayoutRoot.ActualHeight); 



// render the visual element to the WriteableBitmap 

bitmap.Render(this.LayoutRoot, this.transform); 



// request an redraw of the bitmap 

bitmap.Invalidate(); 

保存

private void ThumbnailClicked(object sender, MouseButtonEventArgs e) 

{ 

    // pause the capture timer 

    this.timer.Stop(); 

    try 

    { 

     // locate the WriteableBitmap source for the clicked image 

     WriteableBitmap bitmap = ((Image)sender).Source as WriteableBitmap; 

     if (null == bitmap) 

     { 

      MessageBox.Show("Nothing to save"); 

      return; 

     } 



     // prompt for a location to save it 

     if (this.dialog.ShowDialog() == true) 

     { 

      // the "using" block ensures the stream is cleaned up when we are finished 

      using (Stream stream = this.dialog.OpenFile()) 

      { 

       // encode the stream 

       JPGUtil.EncodeJpg(bitmap, stream); 

      } 

     } 

    } 

    finally 

    { 

     // restart the capture timer 

     this.timer.Start(); 

    }
