Public Function Or (value As BitArray) As BitArray
Parameter
- value
- BitArray
Das Array, mit dem die bitweise OR-Operation ausgeführt werden soll.
Gibt zurück
Ein Array, das das Ergebnis der bitweisen OR-Operation enthält. Hierbei handelt es sich um einen Verweis auf das aktuelle BitArray-Objekt.
Ausnahmen
value
ist null
.
value
und das aktuelle BitArray enthalten nicht die gleiche Anzahl von Elementen.
Beispiele
Das folgende Codebeispiel zeigt, wie der OR-Vorgang zwischen zwei BitArray Objekten ausgeführt wird.
using namespace System;
using namespace System::Collections;
void PrintValues( IEnumerable^ myList, int myWidth );
int main()
{
// Creates and initializes two BitArrays of the same size.
BitArray^ myBA1 = gcnew BitArray( 4 );
BitArray^ myBA2 = gcnew BitArray( 4 );

myBA1[ 3 ] = true;
myBA2[ 0 ] = false;

// Performs a bitwise OR operation between BitArray instances of the same size.

Hinweise
Der bitweise OR-Vorgang gibt zurück true
, wenn einer oder beide Operanden sind true
, und gibt zurück false
, wenn beide Operanden sind false
.
Diese Methode ist ein O(n)
Vorgang, wobei n
.Count
