C# Lambda expressions and NHibernate

Question

I\'m a newbie in the great world of NHibernate. I\'m using version 2.0.1.GA. Here\'s my question. I have a table Cars with column Manufacturer(nvarchar(50

Answer 1

You could probably do this with NHibernate.Linq. It is in a usable form, but still a ways from being complete. Its currently living inside nhcontrib, the only way to get it is to pull it out of svn here https://nhcontrib.svn.sourceforge.net/svnroot/nhcontrib/trunk/src/NHibernate.Linq/

Answer 2

Like Google Ninja said, you can do it with NHibernate.Linq. The query would then be:

session.Linq<Car>.Where(c => c.Manufacturer == "Mercedes").ToList()

If someone ends up here and is using NH3.0 the syntax is just a tad different (thanks to Michael Mrozek and Mike for the suggestion):

session.Query<Car>.Where(c => c.Manufacturer == "Mercedes").ToList()

I've used a binary that came bundled with fluent-nhibernate that works with 2.0GA (I think, not sure about the particular revision).

Answer 3

You can find what you are looking for here (blog entry) or here (google repository)

Answer 4

Look at this question here. Someone had the same worry, and from I can gather, NHibernate.Linq is well alive.

Answer 5

If you don't want to use Linq to NHibernate yet, there's a couple of alternatives to get strongly type Criteria queries:
