C# - BitArray.Or() Method with Example

In this tutorial, we will learn about the C# BitArray.Or() method with its definition, usage, syntax, and example. By Nidhi Last updated : March 31, 2023

BitArray.Or() Method

The BitArray.Or() method is used to perform bitwise OR operation between elements of two BitArray objects. The current BitArray object will be modified to store resultant elements.

Syntax

BitArray BitArray.Or(BitArray value);

Parameter(s)

• value: The array with which to perform the bitwise OR operation.

Return Value

It returns resultant an array, which is a reference to the current BitArray object.

Exception(s)

• System.ArgumentException
• System.ArgumentNullException

C# Example of BitArray.Or() Method

The source code to perform the bitwise OR operation between BitArray elements is given below. The given program is compiled and executed successfully.

using System;
using System.Collections;

class BitArrayEx {
  //Entry point of Program
  static public void Main() {
    //Creation of BitArray objects
    BitArray bitArr1 = new BitArray(3);
    BitArray bitArr2 = new BitArray(3);
    BitArray bitArr3;

    int index = 0;

    bitArr1[0] = true;
    bitArr1[1] = false;
    bitArr1[2] = false;

    bitArr2[0] = true;
    bitArr2[1] = true;
    bitArr2[2] = false;

    bitArr3 = bitArr1.Or(bitArr2);

    Console.WriteLine("Elements of BitArray after Bitwise Or Operation:");
    for (index = 0; index < bitArr3.Length; index++) {
      Console.WriteLine("\tIndex " + index + ": " + bitArr3.Get(index));
    }
  }
}

Output

Elements of BitArray after Bitwise Or Operation:
        Index 0: True
        Index 1: True
        Index 2: False
Press any key to continue . . .
