The BitConverter Class

C# provides a simple class, BitConverter, to simplify the conversion of primitive data types to an array of bytes and vice versa. 

using System;

class Program
{
    static void Main()
    {
        // Create an array of bytes
        byte[] byteArray = { 72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100 };

        // Convert bytes to string
        string resultString = Encoding.UTF8.GetString(byteArray);

        // Display the result
        Console.WriteLine("Byte to String Conversion Result: " + resultString);
    }
}

Output:

Byte to String Conversion Result: Hello World
