Uwagi

Po wywołaniu tej metody element w myArray[i]lokalizacji , gdzie i jest dowolnym indeksem w tablicy, przechodzi do myArray[j]metody , gdzie j równa (myArray.Length + myArray.GetLowerBound(0)) - (i - myArray.GetLowerBound(0)) - 1się .

Ta metoda jest operacją O(), gdzie n jest wartością Lengtharray.n

W języku F# można zamiast tego użyć funkcji Array.rev .

Jak pokazano w poniższym przykładzie, Reverse można użyć metody do odwrócenia tablicy poszarpanej. Inicjuje poszarpaną tablicę z jednym elementem dla każdego miesiąca bieżącego roku w kalendarzu bieżącej kultury. Każdy element zawiera tablicę z dowolną liczbą elementów w danym miesiącu. W przykładzie wyświetlana jest zawartość tablicy, wywołuje metodę Reverse , a następnie wyświetla zawartość odwróconej tablicy.
