I can\'t see how to

Answer 1

Simply with JsonSubTypes attributes that work with Json.NET

    [JsonConverter(typeof(JsonSubtypes), "is_album")]
    [JsonSubtypes.KnownSubType(typeof(GalleryAlbum), true)]
    [JsonSubtypes.KnownSubType(typeof(GalleryImage), false)]
    public abstract class GalleryItem
    {
        public string id { get; set; }
        public string title { get; set; }
        public string link { get; set; }
        public bool is_album { get; set; }
    }

    public class GalleryImage : GalleryItem
    {
        // ...
    }

    public class GalleryAlbum : GalleryItem
    {
        public int images_count { get; set; }
        public List images { get; set; }
    }
