code to check if palindromic number ort not (c#)

 in main

static void Main(string[] args)
        {
            Console.WriteLine("Give me a number");
            int a  = int.Parse(Console.ReadLine());
            palidrom(a);

        }

in method

static void palidrom(int a)
        {
            int sum = 0;
            int b;
            int number = a;
            while (a>0)
            {
                b = a % 10;
                sum = (sum*10) + b;
                a = a / 10;
            }
            
            if (number == sum)
            {
                Console.WriteLine("it's polidromic");
            }
            else
            {
                Console.WriteLine("it's not polidromic");
            }
        }
