C# | Check if the BitArray is read-only
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:
using System;
using System.Collections;
class GFG {
public static void Main()
{
BitArray myBitArr = new BitArray( new byte [] { 0, 0, 0, 1 });
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.
