    //Creation of BitArray objects
    BitArray bitArr = new BitArray(5);

    int index = 0;

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

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

    bitArr.Length = 3;

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