C# | Check if two BitArray objects are equal

Last Updated : 11 Jul, 2025

Equals(Object) Method

which is inherited from the Object class is used to check if a specified

BitArray

object is equal to another

BitArray

object or not.

Syntax:

public virtual bool Equals (object obj);

Here,

obj

is the object which is to be compared with the current object.

Return Value:

This method return

true

if the specified object is equal to the current object otherwise it returns

false

. Below programs illustrate the use of above-discussed method:

Example 1: CSharp


 // C# code to if specified 
// BitArray object is equal 
// to the current object
using System; 
using System.Collections; 
 
class GFG { 
 
    // Driver code 
    public static void Main() 
    { 
 
        // Creating a BitArray 
        BitArray myBitArr1 = new BitArray(4); 
 
        // Creating a BitArray 
        BitArray myBitArr2 = new BitArray(4); 
 
        // Initializing values in myBitArr1 
        myBitArr1[0] = false; 
        myBitArr1[1] = false; 
        myBitArr1[2] = true; 
        myBitArr1[3] = true; 
 
        // Initializing values in myBitArr2 
        myBitArr2[0] = false; 
        myBitArr2[2] = false; 
        myBitArr2[1] = true; 
        myBitArr2[3] = true; 
       
       // using Equals(Object) method 
       // to check if myBitArr1 is 
       // equal to myBitArr2 or not
       Console.WriteLine(myBitArr1.Equals(myBitArr2));         
    } 
}

Example 2: CSharp


 // C# code to if specified
// BitArray object is equal
// to the current object
using System;
using System.Collections;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a BitArray
        BitArray myBitArr1 = new BitArray(4);

        // Creating a BitArray
        BitArray myBitArr2 = new BitArray(4);

        // Initializing values in myBitArr1
        myBitArr1[0] = false;
        myBitArr1[1] = false;
        myBitArr1[2] = true;
        myBitArr1[3] = true;

        // Initializing values in myBitArr2
        myBitArr2[0] = false;
        myBitArr2[2] = false;
        myBitArr2[1] = true;
        myBitArr2[3] = true;

        // using Equals(Object) method
        // to check if myBitArr1 is
        // equal to myBitArr2 or not
        Console.WriteLine(myBitArr1.Equals(myBitArr2));
        
        // Creating a BitArray
        BitArray myBitArr3 = new BitArray(4);
        
        // assigning myBitArr2 to myBitArr3
        myBitArr3 = myBitArr2;
        
        // using Equals(Object) method
        // to check if myBitArr2 is
        // equal to myBitArr3 or not
        Console.WriteLine(myBitArr2.Equals(myBitArr3));
        
        
    }
}

Note:

If the current instance is a reference type, the

Equals(Object)

method checks for reference equality.
