Answer Snippets (Read the full thread at stackoverflow):
You should have a base class Link as follows
public class Link { public string Href { get; set; } } public class ImageLink : Link { } public class DocumentLink : Link { }
And your values class would look like:
public class Values { public Link[] links... .
