array to dictionary

Question

I'm trying to get this _valueAdds = List<ValueAddedItemHelper> into gridItems (Dictionary) with _valueAdds being the Key and all the values being false. But I'm not sure how to do this with Lamda. This how far I got below. I did succeed in doing it with a while loop but would like learn to do it with Lamda

gridItems = new Dictionary<ValueAddedItemHelper, bool>();
gridItems = _valueAdds.Select(k => new { k }).ToArray().ToDictionary(t => t, false);

Answer 1

_valueAdds.ToDictionary(t => t, t => false);
