Note

Pokud SetValue slouží k přiřazení null k elementu pole typů hodnot, jsou všechna pole elementu inicializována nula.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. Hodnotou prvku není odkaz s hodnotou null a nelze ji najít hledáním odkazu s hodnotou null.The value of the element is not a null reference, and cannot be found by searching for a null reference.

Tato metoda je operace O(1).This method is an O(1) operation.

Note

Pokud SetValue slouží k přiřazení null k elementu pole typů hodnot, jsou všechna pole elementu inicializována nula.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. Hodnotou prvku není odkaz s hodnotou null a nelze ji najít hledáním odkazu s hodnotou null.The value of the element is not a null reference, and cannot be found by searching for a null reference.

 void SetValue(System::Object ^ value, int index1, int index2, int index3);
public void SetValue (object value, int index1, int index2, int index3);
member this.SetValue : obj * int * int * int -> unit
Public Sub SetValue (value As Object, index1 As Integer, index2 As Integer, index3 As Integer)

Parameters

value
Object

Nová hodnota pro zadaného prvku.The new value for the specified element.

index1
Int32

32 celé číslo, které představuje index první dimenze elementu Array, který se má nastavit.A 32-bit integer that represents the first-dimension index of the Array element to set.

index2
Int32

32 celé číslo, které představuje index druhé dimenze elementu Array, který se má nastavit.A 32-bit integer that represents the second-dimension index of the Array element to set.

index3
Int32

32 celé číslo, které představuje index třetí dimenze prvku Array, který se má nastavit.A 32-bit integer that represents the third-dimension index of the Array element to set.

Exceptions

Aktuální Array nemá přesně tři dimenze.The current Array does not have exactly three dimensions.

value nelze přetypovat na typ prvku aktuální Array.value cannot be cast to the element type of the current Array.

index1 nebo index2 nebo index3 jsou mimo rozsah platných indexů pro odpovídající dimenzi aktuálního Array.index1 or index2 or index3 is outside the range of valid indexes for the corresponding dimension of the current Array.

Examples

Následující příklad kódu ukazuje, jak nastavit a získat určitou hodnotu v jednorozměrném nebo vícerozměrném poli.The following code example demonstrates how to set and get a specific value in a one-dimensional or multidimensional array.

Remarks

Metody GetLowerBound a GetUpperBound mohou určit, zda některý z indexů je mimo rozsah.The GetLowerBound and GetUpperBound methods can determine whether any of the indexes is out of bounds.

Tato metoda je operace O(1).This method is an O(1) operation.

Note

Pokud SetValue slouží k přiřazení null k elementu pole typů hodnot, jsou všechna pole elementu inicializována nula.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. Hodnotou prvku není odkaz s hodnotou null a nelze ji najít hledáním odkazu s hodnotou null.The value of the element is not a null reference, and cannot be found by searching for a null reference.
