问题
It's kind of hard to explain what I'm searching for but my example should clarify it.
I have next code:
var schedule = ScheduleUtil.CreateScheduleDto(user, user);
Expect.Call(() => _scheduleRepository.Save(schedule));
Now, what I want to do is when this Save call is made, the schedule.id property should be set to another value (1 for instance).
I do not want to mock schedule. Can this be done? The Save method doesn't return a value, so that's not a possiblity, but I do want the object schedule to be modified.
UPDATE: Maybe a small example will clarify what I exactly want.
Say there's a class with a method Save:
public void Create(Entity entity) { //entity is saved to database //entity.id is updated with the created id in database }
So, before the create, entity.id is -1, after the create it is > 0.
Now, there's a service that uses this Create. Code contracts on this service method say that before it is called, the entity must have an id equal to -1, after it is called it must have an id > 0 (preconditions and postconditions).
So, what I need is something like this:
var entity = new Entity(); //id == -1
Expect.Call(() => _instance.Create(entity);
//Now the entity.id should be a random number > 0. This is what I need, to have Rhino Mocks update the id of entity to a given integer. Is this possible?

No. If you're not mocking the _scheduleRepository, Rhino Mocks doesn't know about it. Why don't you want to mock the _scheduleRepository?
EDIT: Ok, now I see what you want to do. Use the "WhenCalled" extension method to define code to be executed when Rhino.Mocks intercepts the call. Something like this should work:
_scheduleRepository.Expect(s => s.Save(schedule)).WhenCalled(a => ((Schedule) a.Arguments[0]).Id = 1);
