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
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 −
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
