如何以編程方式在Windows Phone上截屏？

Question

我需要使用Windows Phone截圖。我不想用手動模擬器和電源+啓動按鈕來截圖。有什麼可以通過編程完成嗎？

Answer 1

下面是代碼：

private void ApplicationBarScreenshotButton_Click(object sender, EventArgs e) 
{ 
    var fileName = String.Format("MyImage_{0:}.jpg", DateTime.Now.Ticks); 
    WriteableBitmap bmpCurrentScreenImage = new WriteableBitmap((int)this.ActualWidth, (int)this.ActualHeight); 
    bmpCurrentScreenImage.Render(LayoutRoot, new MatrixTransform()); 
    bmpCurrentScreenImage.Invalidate(); 
    SaveToMediaLibrary(bmpCurrentScreenImage, fileName, 100); 
    MessageBox.Show("Captured image " + fileName + " Saved Sucessfully", "WP Capture Screen", MessageBoxButton.OK); 

    currentFileName = fileName; 
} 

public void SaveToMediaLibrary(WriteableBitmap bitmap, string name, int quality) 
{ 
    using (var stream = new MemoryStream()) 
    { 
     // Save the picture to the Windows Phone media library. 
     bitmap.SaveJpeg(stream, bitmap.PixelWidth, bitmap.PixelHeight, 0, quality); 
     stream.Seek(0, SeekOrigin.Begin); 
     new MediaLibrary().SavePicture(name, stream); 
    } 
} 

當你點擊AppBar按鈕，它會採取截圖和圖片保存到Windows Phone媒體庫
