This method determines equality using the default comparer Comparer<T>::Default. Comparer<T>::Default checks whether type T implements System::IComparable<T> and uses that implementation, if available. If not, Comparer<T>::Default checks whether type T implements System::IComparable. If type T does not implement either interface, this method uses Object::Equals.
This method is an O(n) operation, where n is Count.
