0359 BitArray
<![CDATA[
A BitArray is a dynamically sized collection of compacted bool values.
BitArray has the following methods:
public sealed class BitArray : ICollection, IEnumerable, ICloneable
{
// Constructors
public BitArray (BitArray bits); // An existing BitArray to copy
public BitArray (int length); // Capacity, in bits
public BitArray (bool[] values);
public BitArray (byte[] bytes);
public BitArray (int[] values);
public BitArray (int length, bool defaultValue);
// To get/set value
public bool this [int index] { get; set; }
public bool Get (int index);
public void Set (int index, bool value);
public void SetAll (bool value);
// Bitwise operators public BitArray Not();
public BitArray And (BitArray value);
public BitArray Or (BitArray value);
public BitArray Xor (BitArray value);
// Copying
public void CopyTo (Array array, int index);
public object Clone();
// Other
public IEnumerator GetEnumerator();
public int Count { get; }
public int Length { get; set; }
public bool IsReadOnly { get; }
public bool IsSynchronized { get; }
public object SyncRoot { get; }
}
The following is an example of using the BitArray class:
using System;
using System.Collections;
using System.Collections.Generic;
using System.Linq;
class Sample
{
public static void Main()
{
var bits = new BitArray(2);
bits[1] = true;
bits.Xor(bits); // Bitwise exclusive-OR bits with itself
Console.WriteLine(bits[1]); // False
}
}
The output:
False
