Multiple constructors

Hi,
I have a class with three constuctors and I want to mock all three constructors. Do I declare three mockobjects to do this as such:

MockObj C1 = MockManager.MockObject(TypeOf(Something),Constructor.Mocked)

MockObj C2 = MockManager.MockObject(TypeOf(Something),Constructor.Mocked,null)

MockObj C3 = MockManager.MockObject(TypeOf(Something),Constructor.Mock,null,null)

Or is there any easier way to do this?
