How to check if a number is palindrome recursively in C#

Answer 1

using System;

namespace ConsoleApplication_C_Sharp
{
    class Program
    {
        static int inverse_number = 0;

        static void Main(string[] args)
        {
            int n = 12321;

            if (recursiveCheckPalindrome(n) == true)
                Console.WriteLine("Palindrome"); 
            else
                Console.WriteLine("NOT Palindrome");
        }
        public static bool recursiveCheckPalindrome(int n)
        {
            if (n == 0)
                return false;
            inverse_number = (inverse_number * 10) + (n % 10);
            recursiveCheckPalindrome(n / 10);

            return n == inverse_number;
        }
    }
}
