Windows Phone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：

public void CaptureScreen(object sender, EventArgs e)

{

    WriteableBitmap bmp = new WriteableBitmap(480, 800);

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

    bmp.Invalidate();



    MemoryStream stream = new MemoryStream();

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

    stream.Seek(0, SeekOrigin.Begin);



    MediaLibrary library = new MediaLibrary();

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

    library.SavePicture(fileName, stream);

    stream.Close();



    Dispatcher.BeginInvoke(() =>

    {

        PictureCollection picCollection = library.Pictures;

        foreach (Picture item in picCollection)

        {

            if (item != null)

            {

                BitmapImage bitmap = new BitmapImage();

                bitmap.SetSource(item.GetImage());

            }

        }

    });

}
