Access Exif metadata

[DGrund]

I am trying to access the Authors fields from a picture.

I am using System.Windows. Media.Imaging;

My code:
BitmapSource img = BitmapFrame.Cre ate(fs);
BitmapMetadata md = (BitmapMetadata )img.Metadata;
lblTitle.Text = md.Title;
lblSubject.Text = md.Subject;
lblAuthors.Text = md.Author; // <======
lblComments.Tex t = md.Comment;
lblDateTaken.Te xt = md.DateTaken;

It doesn't like highlighted line:
Cannot impolicitely convert type "System.Collect ions.ObjectMode l.ReadOnlyColle ction<string> to <string>.

Evidently, I don't have a good enough grasp of C#. Can anyone help?
Thanks in advance.

I've moved your thread into the c# forum as it would appear it's about that language.

Good luck :-)
