Return Anonymous Type from a function

Question

Can I use an anonymous type as a return type in a Function, and then stuff that returned value into an array or collection of some sort whilst also adding an additional fiel

Answer 1

No, you can't return an anonymous type directly, but you can return it using an impromptu interface. Something like this:

public interface IMyInterface
{
    string GroupName { get;  }
    int RowSpan { get; }
}

private IEnumerable GetRowGroups()
{
    var list =
        from item in table
        select new
        {
            GroupName = groupedTable.Key.column1,
            RowSpan = groupedTable.Count()
        }
        .ActLike();

    return list;
}
