Constructors of the BitArray class
BitArray(BitArray)
- Creates a new BitArray class instance with bit values copied from the provided BitArray.
BitArray(Boolean[])
- Creates a new instance of the BitArray class with bit values copied from the provided Boolean array.
BitArray(Byte[])
- Creates a new BitArray instance with bit values copied from the provided array of bytes.
BitArray(Int32)
- Creates a new BitArray object that can store the specified number of bit values initially set to false.
BitArray(Int32, Boolean)
- Creates a new BitArray instance that can store the provided number of bit values initially set to the supplied value.
BitArray(Int32[])
- Creates a new instance of the BitArray class with bit values copied from the provided 32-bit integer array.
Example
using System;
using System.Collections;
class ExampleCode{
public static void Main()
{
// Creating a BitArray
BitArray Bitarr = new BitArray(5);
Bitarr[0] = false;
Bitarr[1] = false;
Bitarr[2] = true;
Bitarr[3] = false;
Bitarr[4] = true;
Console.WriteLine(Bitarr.Get(2));
Console.WriteLine(Bitarr.Get(3));
}
}
Output
True
False
Properties of the BitArray Class
- Count - Count the number of elements in the BitArray.
- IsReadOnly - Check whether the BitArray is read-only or not.
- Item - Gets or sets the bit value at a certain point in the BitArray.
- Length - Gets and sets the number of elements in the BitArray.
- SyncRoot - Gets an object that can be used to synchronize access to the BitArray.
Example
using System;
using System.Collections;
class ExampleProgram{
public static void Main()
{
BitArray arr = new BitArray(new byte[] {1, 2, 3, 4});
Console.WriteLine(arr.IsReadOnly);
Console.WriteLine(arr.Count);
}
}
Output
False
32
Methods of the BitArray Class
- public BitArray And(BitArray value): Compares the items in the current BitArray to the equivalent elements in the provided BitArray in a bitwise AND operation.
- public bool Get(int index): Returns the value of the bit at a specific position in the BitArray.
- public BitArray Not(): Inverts all the bit values in the current BitArray, converting true items to false and false elements to true.
- public BitArray Or(BitArray value): Compares the items in the current BitArray to the equivalent elements in the provided BitArray in a bitwise OR operation.
- public void Set(int index, bool value): Sets a bit in the BitArray to the provided value at a specific point.
- public void SetAll(bool value): Sets the given value to all bits in the BitArray.
- public BitArray Xor(BitArray value): Compares the elements in the current BitArray to the corresponding elements in the provided BitArray in a bitwise exclusive OR operation.
Example
using System;
using System.Collections;
class ExampleProgram{
public static void Main()
{
BitArray Arr1 = new BitArray(4);
BitArray Arr2 = new BitArray(4);
Arr1[0] = false;
Arr1[1] = false;
Arr1[2] = true;
Arr1[3] = true;
Arr2[0] = false;
Arr2[2] = false;
Arr2[1] = true;
Arr2[3] = true;
PrintValues(Arr1.Or(Arr2));
}
public static void PrintValues(IEnumerable myList)
{
foreach(Object obj in myList)
{
Console.WriteLine(obj);
}
}
}
Output
False
True
True
True
Must Read IEnumerable vs IQueryable.
Frequently Asked Questions
What are the properties of a BitArray Class in C#?
The BitArray class is a collection where the capacity and count are always equal. The Length attribute is used to add elements to a BitArray. The Length attribute is used to delete elements. An integer index can be used to access elements in this collection. This collection's indexes are all zero-based.
What is the main functioning of BitArray Class in C#?
The BitArray class keeps track of a compact array of bit values represented as Booleans, with true indicating that a bit is on and false indicating that it is off.
BitArray class is present in which namespace?
The namespace System.Collections contain this class.
