Question

I have a Class A that have a class B List …
So, with QueryOver I have :

ClassB lb = null;  
var result = session.QueryOver<ClassA>
        .JoinAlias(x => x.ListB, () => lb, JoinType.LeftOuterJoin)
        .Where(() => lb.Property == 1)
        .List<ClassA>();

How Can I do that using Nhibernate Query<> ?

Thanks

Assuming what you want to do is get a list of ClassA having at least one ClassB with Property == 1:

var result = session.Query<ClassA>()
                    .Where(a => a.ListB.Any(b => b.Property == 1))
                    .ToList();

This wouldn’t be an outer join, though. You might emulate that by adding || !a.ListB.Any().
