Unsigned Byte Array with Example in C#

C# Unsigned Byte Array: Here, we will find out about the unsigned byte array in C# – how to announce, how to instate and how to get to components?

Unsigned Byte Array in C#

In C#.Net, we can make an unsigned byte array by utilizing byte, a byte is utilized to store just positive qualities between the scope of 0 to 255 (Unsigned 8 bits integer).

It involves 1-byte memory for every component, if the array size is 10, it will take 10 bytes memory.

The assertion of an unsigned byte[]

1) Array statement with instatement

    Syntax:	sbyte[] array_name = { byte1, byte2, byte2, ...};
    Example:	sbyte[] arr1 = { -128, -100, 0, 100, 127};

2) Array statement with a fixed number

    Syntax:	sbyte[] array_name = new sbyte[value];
    Example:	sbyte[] arr2 = new sbyte[5];

3) Array declaration with user input

    Syntax:	sbyte[] array_name = new sbyte[variable];
    Example:	sbyte[] arr3 = new sbyte[n];

Getting to unsigned byte array’s components

Like different sorts of arrays – we can get to the array components with its record, the list begins with 0 and finishes with n-1. Here, n is the all outnumber of array components.

Example:

Think about the given example – Here, we are announcing 3 arrays with 3 distinct methodologies, instating the arrays either with default esteems or client input. To print the array components, we are utilizing foreach loop, we can likewise use for or while loop with loop counter to get to the array components.

using System;
using System.Text;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            //declaring unsigned byte[] & initializing it with 5 elements
            byte[] arr1 = { 0, 100, 120, 210, 255};
            
            //printing all bytes of arr1
            Console.WriteLine("arr1 items...");
            foreach (byte item in arr1)
            {
                Console.WriteLine(item);
            }

            Console.WriteLine(); //to print a line 

            //declaring array for 5 elements 
            //reading values and assigning to array 
            byte[] arr2 = new byte[5];
            //reading values from the user
            for (int loop = 0; loop < 5; loop++)
            {
                Console.Write("Enter a byte (b/w -128 to 127): ");
                arr2[loop] = byte.Parse(Console.ReadLine());
            }
            //printing all bytes of arr2
            Console.WriteLine("arr2 items...");
            foreach (byte item in arr2)
            {
                Console.WriteLine(item);
            }

            Console.WriteLine(); //to print a line 

            //read value of "n" and declare array for "n" elements
            //reading values and assigning to array 
            Console.Write("Enter length of the array: ");
            int n = int.Parse(Console.ReadLine());
            //declaring array for n elements
            byte[] arr3 = new byte[n];
            //reading values from the user
            for (int loop = 0; loop < n; loop++)
            {
                Console.Write("Enter a byte (b/w -128 to 127): ");
                arr3[loop] = byte.Parse(Console.ReadLine());
            }
            //printing all bytes of arr3
            Console.WriteLine("arr3 items...");
            foreach (byte item in arr3)
            {
                Console.WriteLine(item);
            }

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output:

arr1 items...
