Hinweise

Die Methoden GetLowerBound und GetUpperBound können bestimmen, ob der Wert von index außerhalb des gültigen Bereichs liegt.The GetLowerBound and GetUpperBound methods can determine whether the value of index is out of bounds.

Diese Methode ist ein O (1)-Vorgang.This method is an O(1) operation.

Hinweis

Wenn SetValue verwendet wird, um null einem Element eines Arrays von Werttypen zuzuweisen, werden alle Felder des-Elements mit 0 (null) initialisiert.If SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. Der Wert des-Elements ist kein NULL-Verweis und kann nicht gefunden werden, wenn Sie nach einem NULL-Verweis suchen.The value of the element is not a null reference, and cannot be found by searching for a null reference.

Wenn SetValue verwendet wird, um null einem Element eines Arrays von Werttypen zuzuweisen, werden alle Felder des-Elements mit 0 (null) initialisiert.If SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. Der Wert des-Elements ist kein NULL-Verweis und kann nicht gefunden werden, wenn Sie nach einem NULL-Verweis suchen.The value of the element is not a null reference, and cannot be found by searching for a null reference.

Hinweise

Die Methoden GetLowerBound und GetUpperBound können bestimmen, ob die Indizes außerhalb des gültigen Bereichs liegen.The GetLowerBound and GetUpperBound methods can determine whether any of the indexes is out of bounds.

Diese Methode ist ein O (1)-Vorgang.This method is an O(1) operation.

Hinweis

Wenn SetValue verwendet wird, um null einem Element eines Arrays von Werttypen zuzuweisen, werden alle Felder des-Elements mit 0 (null) initialisiert.If SetValue is used to assign null to an element of an array of value types, all fields of the element are initialized to zero. Der Wert des-Elements ist kein NULL-Verweis und kann nicht gefunden werden, wenn Sie nach einem NULL-Verweis suchen.The value of the element is not a null reference, and cannot be found by searching for a null reference.
