Przykłady
Poniższy przykład wywołuje metodę TimeZoneInfo.AdjustmentRule.Equals(TimeZoneInfo+AdjustmentRule) w celu porównania reguł korekty dla czasu centralnego (standardowego) z regułami dotyczącymi czasu centralnego (czas standardowy) i Meksyku (czas standardowy).

Uwagi
Aby określić, czy dwa TimeZoneInfo.AdjustmentRule obiekty są równe, Equals(TimeZoneInfo+AdjustmentRule) metoda porównuje wartości składowe każdego obiektu. Dwie reguły korekty są równe, jeśli mają te same daty obowiązujące, te same różnice i identyczne wartości dla TimeZoneInfo.TransitionTime obiektów zwracanych przez ich DaylightTransitionStart właściwości i DaylightTransitionEnd .
