How do I retrieve the first item in a CharArray to display in ListView

I have a CharArray that contains this informaiton.

https://www.website.com/filename.jpg,https://www.website.com/filename2.jpg,https://www.website.com/filename3.jpg,https://www.website.com/filename4.jpg

I can list all the image URL's in a ListView fine with this query

var photos = new EntityContainer();
        string photoUrls = (from p in content.Inventories
                            select p.ImageList).FirstOrDefault();

        string[] values = photoUrls.Split(",".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
        PhotoListRepeater.DataSource = values;
        PhotoListRepeater.DataBind();

But how do I retrieve only the first record in the DataSource so the result would be the first image in the list?

Thanks in advance
