WebBrowser没有在Windows Phone中捕获

Question

我正在使用以下代码捕获屏幕。 但是没有捕获页面中的浏览器。

WriteableBitmap w = new System.Windows.Media.Imaging.WriteableBitmap(this, null); // 'this' is your current page
WriteableBitmap w2 = new System.Windows.Media.Imaging.WriteableBitmap(480, 800);

// space for SysTray
for (int i = 0; i < 32; i++)
{
            for (int j = 0; j < 480; j++)
            {
                w2.Pixels[i * 480 + j] = -16777216; // black #ff000000
            }
}

// actual client area
for (int i = 32; i < 728; i++)
{
            for (int j = 0; j < 480; j++)
            {
                w2.Pixels[i * 480 + j] = w.Pixels[(i - 32) * 480 + j];
            }
}

// space for AppBar
for (int i = 728; i < 800; i++)
{
            for (int j = 0; j < 480; j++)
            {
                w2.Pixels[i * 480 + j] = -16777216; // black #ff000000
            }
}

MemoryStream ms = new MemoryStream();
w2.SaveJpeg(ms, 480, 800, 0, 100);

Microsoft.Xna.Framework.Media.MediaLibrary lib = new Microsoft.Xna.Framework.Media.MediaLibrary();
ms.Position = 0;
lib.SavePicture("screenshot", ms);

当前的Windows Phone SDK是一个已知问题：

WriteableBitmap当前不捕获WebBrowser控件或MediaElement的内容。
