Linq For NHibernateOrderring and Paging
time to read 1 min | 170 words
Bobby Diaz has implemented orderring and paging support for Linq to NHibernate, so this works:
(from c in nwnd.Customers select c.CustomerID)
.Skip(10).Take(10).ToList();
As well as this:
var query = from c in nwnd.Customers
where c.Country == "Belgium"
orderby c.Country descending, c.City descending
select c.City;
where c.Country == "Belgium"
orderby c.Country descending, c.City descending
select c.City;
Thanks again, Bobby, and the new code is on SVN.

Linq is some neat stuff. Too bad that, if the VS 2005 dev time was any indication, we'll all have this around..oh...2010.
This project is making a lot of progress... Fast !
Keep the good work and thanks.
In an effort to help myself figure out what the expression trees look like when passed to an IQueryable, I put together a utility class that dumps an expression tree to XML. Hopefully others looking to contribute to this project can find some use in it. It's quick-and-nasty code, but seems to generally work.

Jon,
This looks good! I was actually thinking of writing something similar to enumerate the tree in code looking for certain information. I will definately put this to some use!
