C# | Check if the BitArray is read-only

Last Updated : 01 Feb, 2019

The BitArray class manages a compact array of bit values, which are represented as Booleans, where true indicates that the bit is on i.e, 1 and false indicates the bit is off i.e, 0. This class is contained in System.Collections namespace. BitArray.IsReadOnly property is used to get a value indicating whether the BitArray is read-only or not. Properties:

The BitArray class is a collection class in which the capacity is always the same as the count.
Elements are added to a BitArray by increasing the Length property.
Elements are deleted by decreasing the Length property.
Elements in this collection can be accessed using an integer index. Indexes in this collection are zero-based.

Syntax:

public bool IsReadOnly { get; }

Return Value: This property is always false. Example:

CSHARP

// C# code to check if the
// BitArray is read-only
using System;
using System.Collections;

class GFG {

    // Driver code
    public static void Main()
    {

        // Creating a BitArray
        BitArray myBitArr = new BitArray(new byte[] { 0, 0, 0, 1 });

        // Checking if the BitArray is read-only
        Console.WriteLine(myBitArr.IsReadOnly);
    }
}

Output:

False

Note:

A collection that is read-only does not allow the addition, removal, or modification of elements after the collection is created.
This method is an O(1) operation.
A collection that is read-only is simply a collection with a wrapper that prevents modifying the collection. Therefore, if changes are made to the underlying collection, the read-only collection reflects those changes.
