sir I send you the simplest using a array

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Arraymatrix
{
class Program
{
static void Main(string[] args)
{
int[] arr ={1,8,9,16};
for(int i =0;i<4;i++)
{
for(int j=0;j<4;j++)
{
Console.Write(arr[j] + " ");
if(j%2 == 0)
arr[j] = arr[j] +1;
else
arr[j] = arr[j] - 1;
}
Console.WriteLine();
}
Console.ReadKey();
}
}
}

Hi Harish,
Please try this code
public static void TestMatrix(int[] arr)
{
    int row = 4;
    int col = 4;
    int temp = 0;

    int[,] result = new int[row, col];
    int count = 0;


    for (int i = 0; i < col; i++)
    {
        for (int j = 0; j < row; j++)
        {
            if ((i + 1) % 2 == 0)
            {
                temp = count-j;
                result[j, i] = arr[temp + row - j - 1];
                count++;
            }
            else
            {
                result[j, i] = arr[count];
                count++;
            }
        }
    }
    for (int i = 0; i < row; i++)
    {
        for (int j = 0; j < col; j++)
        {
            Console.Write(result[i, j] + " ");
        }
        Console.WriteLine();
    }
}
call this method like this
int[] arr = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,13,14,15,16 };
TestMatrix(arr);
Please try and let me know if you have any doubts

for(nt j=0;j<4;j++)
{
Console.print(arr[i]);
