Question:
I've just downloaded the Linq provider for NHibernate and am just a little excited. But I don't know Linq syntax that well.
I can return whole objects from a query like this:
var query = from foo in session.Linq<Kctc.BusinessLayer.Domain.Case>() where foo.CaseNumber > 0 select foo;
And I can select a single property like this:
var query = from foo in session.Linq<Kctc.BusinessLayer.Domain.Case>() where foo.CaseNumber > 0 select foo.Id;
But how would I select two properties, e.g. foo.Id and foo.Bar? Or is that not possible?
Thanks
David
Solution:1
Use an anonymous projection:
var query = from foo in session.Linq<Kctc.BusinessLayer.Domain.Case>() where foo.CaseNumber > 0 select new { foo.Id, foo.Bar };
Solution:2
You have to create a new Anonymous
type, that will only be available in the current scope (i.e. it can't be returned from a method etc.)
var query = from foo in session.Linq<Kctc.BusinessLayer.Domain.Case>() where foo.CaseNumber > 0 select new { foo.Id, foo.Bar };
Or you can create a custom class and populate that.
