        {
            await CrossMedia.Current.Initialize();
            if (CrossMedia.Current.IsPickPhotoSupported)
            {
                var mediaOption = new PickMediaOptions
                {

                var multiPickOptions = new MultiPickerOptions 
                { 
                    MaximumImagesCount = 100
                };

                var files = await CrossMedia.Current.PickPhotosAsync(mediaOption, multiPickOptions, cancellation);
                if (files != null)
                {

                    var mapped = from file in files
                                 select new StockGalleryPickerMediaFile(file.Path, file.GetStreamWithImageRotatedForExternalStorage);
                    var results = new StockGalleryPickerSet()
                    {
                        Items = mapped.ToList()
                    };

                    return results;

This is just multiple selection without sequence, or the sequence is the sequence of pictures rather than the sequence of selection. For example, the disordered effect of realizing the sequence of pictures with selection serial numbers rather than checklists should be realized manually.
