BitArray Class in C#

The BitArray class manages a compact array of bit values, which are represented as Booleans, where true indicates that the bit is on (1) and false indicates the bit is off (0).

The following table lists some of the commonly used methods of the BitArray class −

Example

Let us now see an example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(){
      BitArray arr1 = new BitArray(2);
      BitArray arr2 = new BitArray(2);
      arr1[0] = false;
      arr1[1] = true;
      Console.WriteLine("Elements in BitArray1...");
      foreach (bool res in arr1){
         Console.WriteLine(res);
      }
      arr2[0] = false;
      arr2[1] = true;
      Console.WriteLine("Elements in BitArray2...");
      foreach (bool res in arr2){
         Console.WriteLine(res);
      }
      Console.WriteLine("Is BitArray1 equal to BitArray2? = "+arr2.Equals(arr1));
      Console.WriteLine("Is BitArray synchronized? = "+arr2.IsSynchronized);
      Console.WriteLine("Is BitArray read-only? = "+arr2.IsReadOnly);
   }
}

Output

This will produce the following output −

Elements in BitArray1...
False
True
Elements in BitArray2...
False
True
Is BitArray1 equal to BitArray2? = False
Is BitArray synchronized? = False
Is BitArray read-only? = False

Example

Let us see another example to implement Bitwise exclusive OR operation between elements of BitArray −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(){
      BitArray arr1 = new BitArray(5);
      BitArray arr2 = new BitArray(5);
      arr1[0] = false;
      arr1[1] = false;
      arr2[0] = false;
      arr2[1] = true;
      Console.WriteLine("BitArray1 elements...");
      foreach (bool res in arr1){
         Console.WriteLine(res);
      }
      Console.WriteLine("
BitArray2 elements...");
      foreach (bool res in arr2){
         Console.WriteLine(res);
      }
      Console.WriteLine("
Bitwise exclusive OR operation...");
      IEnumerable demoEnum = arr1.Xor(arr2);
      foreach(Object ob in demoEnum){
         Console.WriteLine(ob);
      }
   }
}

Output

This will produce the following output −

BitArray1 elements...
False
False
False
False
False

BitArray2 elements...
False
True
False
False
False

Bitwise exclusive OR operation...
False
True
False
False
False
