Possible to assign a data type to an anonymous type's members in a linq query?

Programmer Question

If I have a linq query that creates the anonymous type below:

                    select new
                    {
                        lf.id,
                        lf.name,
                        lf.desc,
                        plf.childId
                    };

Is it possible to assign a specific type to one of the members? Specifically I would like to make lf.id a null-able int rather than an int...
