            property = await selectedFile.Properties.GetMusicPropertiesAsync();

            txtAlbum.Text = property.Album;
            txtAlbumArtist.Text = property.AlbumArtist;
            txtArtist.Text = property.Artist;
            txtPublisher.Text = property.Publisher;
            txtRating.Text = property.Rating.ToString();
            txtSubtitle.Text = property.Subtitle;
            txtTitle.Text = property.Title;
            txtTrackNumber.Text = property.TrackNumber.ToString();
            txtYears.Text = property.Year.ToString();
            lblBitRate.Text = property.Bitrate.ToString();
            lblComposer.Text = string.Join(" , ", property.Composers.ToArray());
            lblConductors.Text = string.Join(" , ", property.Conductors.ToArray());
            lblDuration.Text = property.Duration.Minutes.ToString() + ":" + property.Duration.Seconds.ToString();
            lblGenre.Text = string.Join(" , ", property.Genre.ToArray());
            lblMediaTitle.Text = selectedFile.Name;
            txtFileName.Text = selectedFile.Name;
            lblFileType.Text = selectedFile.FileType;
            lblProducers.Text = string.Join(" , ", property.Producers.ToArray());
            lblWriters.Text = string.Join(" , ", property.Writers.ToArray());
        
        }

private void btnSave_Click(object sender, RoutedEventArgs e)
        {
            //property = await selectedFile.Properties.GetMusicPropertiesAsync();
            property.Album = txtAlbum.Text;
            property.AlbumArtist = txtAlbumArtist.Text;
            property.Artist = txtArtist.Text;
            property.Publisher = txtPublisher.Text;
            property.Rating = uint.Parse(txtRating.Text);
            property.Subtitle = txtSubtitle.Text;
            property.Title = txtTitle.Text;
            property.TrackNumber = uint.Parse(txtTrackNumber.Text);
            property.Year = uint.Parse(txtYears.Text);
            SaveProperties(property,txtFileName.Text);   
        }
        private async void SaveProperties(Windows.Storage.FileProperties.MusicProperties prop , string Name) {
            await property.SavePropertiesAsync();
        }
