wp8 入门到精通 启动系统分享照片任务

PhotoChooserTask photoChooserTask = new PhotoChooserTask();

photoChooserTask.Completed += photoChooserTask_Completed;
photoChooserTask.ShowCamera = true;
photoChooserTask.Show();

void photoChooserTask_Completed(object sender, PhotoResult e)
{
if (e.TaskResult == TaskResult.OK)
{
ShowShareMediaTask(e.OriginalFileName);
}
}
void ShowShareMediaTask(string path)
{
ShareMediaTask shareMediaTask = new ShareMediaTask();
shareMediaTask.FilePath = path;
shareMediaTask.Show();
}

二。从系统相册里启动分享

    public class PicturesAlbum : ObservableCollection<FlowItem>
    {
        public PicturesAlbum()
        {
            using (var library = new MediaLibrary())
            {
                PictureAlbumCollection allAlbums = library.RootPictureAlbum.Albums;

                PictureAlbum cameraRoll = allAlbums.Where(album => album.Name == "Saved Pictures").FirstOrDefault();

                var CameraRollPictures = cameraRoll.Pictures;
                foreach (Picture _p in library.Pictures)
                {
                    Stream _s = _p.GetImage();
                    BitmapImage _bi = new BitmapImage();
                    _bi.SetSource(_s);

                    FlowItem _w = new FlowItem();
                    _w.Picture = _bi;
                    _w.Name = _p.Name;
                    _w.Date = _p.Date;

                    ImageBrush ib = new ImageBrush();
                    ib.ImageSource = _bi;

                    _w.BackupgroupPicture = ib;

                    this.Add(_w);
                }
            }
        }
    }
