What is the BitArray class in C#?
The BitArray class is used when you need to store the bits but do not know the number of bits in advance.
The following are some of the properties of the BitArray class in C# −
| Sr.No. | Property & Description |
|---|---|
| 1 | Count Gets the number of elements contained in the BitArray. |
| 2 | IsReadOnly Gets a value indicating whether the BitArray is read-only. |
| 3 | Item Gets or sets the value of the bit at a specific position in the BitArray. |
| 4 | Length Gets or sets the number of elements in the BitArray. |
Let us see how to work with IsReadOnly property in C#.
With IsReadOnly class, you can get a value indicating whether the BitArray is read-only or not. ReadOnly will not allow you to add new elements to the BitArray.
The following is our example stating how to use the IsReadOnly property of BitArray class in C# −
Example
using System;
using System.Collections;
namespace Demo {
class Program {
static void Main(string[] args) {
BitArray ba1 = new BitArray(5);
BitArray ba2 = new BitArray(5);
byte[] a = { 90 };
byte[] b = { 30 };
ba1 = new BitArray(a);
ba2 = new BitArray(b);
Console.WriteLine("Bit array ba1: 60");
for (int i = 0; i < ba1.Count; i++) {
Console.Write("{0, -4} ", ba1[i]);
}
Console.WriteLine();
Console.WriteLine("IsReadOnly = " + ba1.IsReadOnly);
Console.WriteLine("IsReadOnly = " + ba2.IsReadOnly);
Console.ReadKey();
}
}
}
