Number of elements contained in the BitArray in C#?

To get the number of elements contained in the BitArray, the code is as follows −

Example

 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 OR operation...");
      IEnumerable demoEnum = arr1.Or(arr2);
      foreach(Object ob in demoEnum) {
         Console.WriteLine(ob);
      }
      Console.WriteLine("
Number of elements in the resultant BitArray = "+arr1.Count);
   }
}

Output

This will produce the following output −

BitArray1 elements...
False
False
False
False
False
BitArray2 elements...
False
True
False
False
False
Bitwise OR operation...
False
True
False
False
False
Number of elements in the resultany BitArray = 5

Example

Let us now see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      BitArray arr = new BitArray(2);
      arr[0] = false;
      arr[1] = true;
      Console.WriteLine("Elements in BitArray...");
      foreach (bool res in arr) {
         Console.WriteLine(res);
      }
      Console.WriteLine("
Number of elements in the BitArray = "+arr.Count);
      bool[] boolArr = new bool[2];
      boolArr[0] = true;
      boolArr[1] = false;
      arr.CopyTo(boolArr, 0);
      Console.WriteLine("
Array...");
      foreach(Object obj in boolArr) {
         Console.WriteLine(obj);
      }
   }
}

Output

This will produce the following output −

Elements in BitArray...
False
True

Number of elements in the BitArray = 2
Array...
False
True
