Why does conversion between GregorianCalendar and OffsetDateTime fail when evaluating the ZoneInfo part?

I am converting an OffsetDateTime to a GregorianCalendar as part of populating values for an outbound web service. I just thought I'd test the actual conversion. It is failing...

You're currently trying to get properties from data, which is your list - and you're ignoring x, which is the item in the list. I suspect you want: var sendModel = data .Select(x => new Products { Name = x.Name, Price = x.Price }) ... more 3/22/2016 9:02:46 AM
