Can't use .Union with Linq due to

Question

I\'m kind of stuck with that problem. Hope i\'ll get some help. Here\'s the point. I have to fill my DataGridView with that SQL request :

SELECT LOT.NumLot,          


        

Answer 1

When I only look at your last try I see this:

select new { x.NumLot, x.EtatLot, emp.NomEmploye };

vs.

select new { x.NumLot, x.EtatLot, test };

You can never assign or cast one list of anonymous type to another as long as all their properties do not have equal type and name.

EDIT: Write select new { x.NumLot, x.EtatLot, NomEmploye = test }; for the second one instead.
