Uwagi

Metody GetLowerBound i GetUpperBound mogą określać, czy wartość index jest poza granicami.The GetLowerBound and GetUpperBound methods can determine whether the value of index is out of bounds.

Aby uzyskać więcej informacji na temat konwersji, zobacz Convert.For more information about conversions, see Convert.

Ta metoda jest operacją O(1).This method is an O(1) operation.

Uwaga

Jeśli SetValue służy do przypisywania null do elementu tablicy typów wartości, wszystkie pola elementu są inicjowane do zera.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. Wartość elementu nie jest odwołaniem zerowym i nie można jej znaleźć przez wyszukiwanie odwołania zerowego.The value of the element is not a null reference, and cannot be found by searching for a null reference.

Wyjątki

Liczba wymiarów w bieżącej Array nie jest równa liczbie elementów w indices.The number of dimensions in the current Array is not equal to the number of elements in indices.

Jeśli SetValue służy do przypisywania null do elementu tablicy typów wartości, wszystkie pola elementu są inicjowane do zera.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. Wartość elementu nie jest odwołaniem zerowym i nie można jej znaleźć przez wyszukiwanie odwołania zerowego.The value of the element is not a null reference, and cannot be found by searching for a null reference.

Metody GetLowerBound i GetUpperBound mogą określać, czy którykolwiek z indeksów jest poza zakresem.The GetLowerBound and GetUpperBound methods can determine whether any of the indexes is out of bounds.

Ta metoda jest operacją O(1).This method is an O(1) operation.

Uwaga

Jeśli SetValue służy do przypisywania null do elementu tablicy typów wartości, wszystkie pola elementu są inicjowane do zera.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. Wartość elementu nie jest odwołaniem zerowym i nie można jej znaleźć przez wyszukiwanie odwołania zerowego.The value of the element is not a null reference, and cannot be found by searching for a null reference.
