The Given Array is:

int[] arr = new int[] { 1, 2, 3, 4, 5, 6 };

It's output should be :

Print Original Array:1,2,3,4,5,6

Print reversed Array: 6,5,4,3,2,1

using System;

public class Program { public static void Main() { int[] arr = new int[] { 1, 2, 3, 4, 5, 6 };

    //---------------------------------------------------------------------------------------------------------------------
    // 1 Print Array as 1, 2, 3, 4, 5, 6
    //---------------------------------------------------------------------------------------------------------------------
    Console.WriteLine(string.Join(",", arr));
    //---------------------------------------------------------------------------------------------------------------------
    // 2> Write code to reverse it
    //---------------------------------------------------------------------------------------------------------------------     
    int temp=0;
    int left=0,right=arr.Length-1;
    while(left<right)
    {
        temp=arr[left];
        arr[left]=arr[right];
        arr[right]=temp;
        left++;
        right--;
    }       
    //---------------------------------------------------------------------------------------------------------------------
    // 3> Print reversed Array as 6, 5, 4, 3, 2, 1
    //---------------------------------------------------------------------------------------------------------------------
    Console.WriteLine(string.Join(",", arr));
}

using System;
using System.Linq;

public class Program
{
    public static void Main()
    {
        var forward = new int[] { 1, 2, 3, 4, 5, 6 };
        var forwardStr = string.Join(",", forward);
        Console.WriteLine(forwardStr);

        var reverse = forward.Reverse();
        var reverseStr = string.Join(",", reverse);
        Console.WriteLine(reverseStr);
    }
}

You can print a given integer array and then print its reverse in C# using the following code:

using System;

class Program
{
    static void Main()
    {
        
        int[] arr = { 1, 2, 3, 4, 5 };

        foreach (int num in arr)
        {
            Console.Write(num + " ");
        }

        // Reverse the array
        Array.Reverse(arr);

        Console.WriteLine("\nReversed Array:");
        foreach (int num in arr)
        {
           Console.Write(num + " ");
        }

         Console.ReadLine();
    }
}
