BitArray.Or(BitArray) Methode

public:
 System::Collections::BitArray ^ Or(System::Collections::BitArray ^ value);

public System.Collections.BitArray Or(System.Collections.BitArray value);

member this.Or : System.Collections.BitArray -> System.Collections.BitArray

Public Function Or (value As BitArray) As BitArray

Parameter

Gibt zurück

Ein Array, das das Ergebnis des bitweisen OR-Vorgangs enthält, bei dem es sich um einen Verweis auf das aktuelle BitArray Objekt handelt.

Ausnahmen

Beispiele

Das folgende Codebeispiel zeigt, wie der OR-Vorgang zwischen zwei BitArray Objekten ausgeführt wird.

using System;
using System.Collections;
public class SamplesBitArray  {

   public static void Main()  {

      // Creates and initializes two BitArrays of the same size.
      BitArray myBA1 = new BitArray( 4 );
      BitArray myBA2 = new BitArray( 4 );
      myBA1[0] = myBA1[1] = false;
      myBA1[2] = myBA1[3] = true;
      myBA2[0] = myBA2[2] = false;
      myBA2[1] = myBA2[3] = true;

      // Performs a bitwise OR operation between BitArray instances of the same size.
      Console.WriteLine( "Initial values" );
      Console.Write( "myBA1:" );
      PrintValues( myBA1, 8 );
      Console.Write( "myBA2:" );
      PrintValues( myBA2, 8 );
      Console.WriteLine();

      Console.WriteLine( "Result" );
      Console.Write( "OR:" );
      PrintValues( myBA1.Or( myBA2 ), 8 );
      Console.WriteLine();

      Console.WriteLine( "After OR" );
      Console.Write( "myBA1:" );
      PrintValues( myBA1, 8 );
      Console.Write( "myBA2:" );
      PrintValues( myBA2, 8 );
      Console.WriteLine();

      // Performing OR between BitArray instances of different sizes returns an exception.
      try  {
         BitArray myBA3 = new BitArray( 8 );
         myBA3[0] = myBA3[1] = myBA3[2] = myBA3[3] = false;
         myBA3[4] = myBA3[5] = myBA3[6] = myBA3[7] = true;
         myBA1.Or( myBA3 );
      } catch ( Exception myException )  {
         Console.WriteLine("Exception: " + myException.ToString());
      }
   }

   public static void PrintValues( IEnumerable myList, int myWidth )  {
      int i = myWidth;
      foreach ( Object obj in myList ) {
         if ( i <= 0 )  {
            i = myWidth;
            Console.WriteLine();
         }
         i--;
         Console.Write( "{0,8}", obj );
      }
      Console.WriteLine();
   }
}

Hinweise

Der bitweise OR-Vorgang gibt zurück true , wenn ein oder beide Operanden vorhanden sind true, und gibt zurück false , wenn beide Operanden sind false.

Bei dieser Methode handelt es sich um einen Vorgang, bei dem O(n) es sich um einen n Vorgang handeltCount.
