You can argue that you may be able to downcast IPerson to Person, but at this point I would answer telling you that you need to follow your own coding conventions: if you defined that you never return Person but IPerson then I would do it this way in the entire code base, and if you need a write-capable Parents property, then you return Person instead (and you avoid a cast later!).

Exposing the array directly to those using it means that they güç modify it - this is a violation of encapsulation and data hiding.

If you do this then there's nothing stopping your callers casting the IEnumerable back to ICollection and then modifying it. ReadOnlyCollection removes this possibility, although it's still possible to access the underlying writable collection via reflection.

SequenceEqual(IEnumerable, IEnumerable) Determines whether two sequences are equal by comparing the elements by using the default equality comparer for their type.

End Sub And that's all you need to write.
