BitArray.CopyTo() Method

The BitArray.CopyTo() method is used to copy BitArray elements to a one-dimensional array of Boolean values, starting at the specified index of an array.

Syntax

void BitArray.CopyTo(Array array, int arrayIndex);

Parameter(s)

array: An array to copy elements of BitArray.
index: The index in array at which copying begins.

Return Value

It does not return any value.

Exception(s)

System.ArgumentNullException
System.ArgumentOutOfRangeException
System.ArgumentException
System.InvalidCastException

C# Example of BitArray.CopyTo() Method

The source code to copy the entire BitArray to a compatible one-dimensional Array 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(5);
    bool[] Arr = new bool[8];
    int index = 0;

    bitArr1[0] = true;
    bitArr1[1] = false;
    bitArr1[2] = true;
    bitArr1[3] = false;
    bitArr1[4] = true;

    bitArr1.CopyTo(Arr, 0);

    Console.WriteLine("Elements of BitArray1:");
    for (index = 0; index < bitArr1.Length; index++) {
      Console.WriteLine("\tIndex " + index + ": " + bitArr1.Get(index));
    }

    Console.WriteLine("Array Values:");
    for (index = 0; index < Arr.Length; index++) {
      Console.WriteLine("\t" + Arr[index]);
    }
  }
}

Output

Elements of BitArray1:
        Index 0: True 
        Index 1: False
        Index 2: True
        Index 3: False
        Index 4: True
Array Values:
        True
        False
        True
        False
        True
        False
        False
        False
