How to find out key field for nhibernate object

Question

Let's say I have the following request

ICriteria query = session.CreateCriteria(typeof(T));

How can I find out the key field T so that I can add an expression like so:

query.Add(Expression.In(keyField, someListOfObjects.ToArray()));

Any ideas?

Use NH metadata

var meta = factory.GetClassMetadata(typeof(T));

query.Add(Expression.In(meta.IdentifierPropertyName, someListOfObjects.ToArray()));
