C# - BitArray.Not() Method with Example

In this tutorial, we will learn about the C# BitArray.Not() method with its definition, usage, syntax, and example. By Nidhi Last updated : March 31, 2023

BitArray.Not() Method

The BitArray.Not() method is used to perform bitwise NOT operation on elements of BitArray i.e., it inverts all the bits in the current BitArray object.

Syntax

BitArray BitArray.Not();

Parameter(s)

• None

Return Value

It returns modified object values after bitwise NOT operation.

C# Example of BitArray.Not() Method

The source code to invert all the bit values in the current BitArray 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;

    int index = 0;

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

    bitArr2 = bitArr1.Not();

    Console.WriteLine("Elements of BitArray after Bitwise Not Operation:");
    for (index = 0; index < bitArr2.Length; index++) {
      Console.WriteLine("\tIndex " + index + ": " + bitArr2.Get(index));
    }
  }
}

Output

Elements of BitArray after Bitwise Not Operation:
        Index 0: False
        Index 1: True
        Index 2: False
