Private collection mapping in fluent nhibernate

Question

How can I map this:

public class Customer
{
   private IList _orders;
   public IEnumerable 
   GetAllOrders()
   {
      return _o         


        

Answer 1

You can map a completely private collection using Reveal.Member(), but it has a specific and non-obvious restriction: the Expression that HasMany() accepts has to return either IEnumerable or object.

For your class:

public class Customer
{
    private IList _orders;
    public IEnumerable GetAllOrders()
    {
        return _orders;     
    }
}

the following line will populate the _orders collection:

HasMany(Reveal.Member>("_orders"));
    //additional mapping behaviors

For completeness - the following line gives a compiler error:

HasMany(Reveal.Member>("_orders"));
