How to check whether a numbers are palindrome in base 10 and base 2 with C#

Answer 1

using System;
using System.Linq;
  
public class MyClass
{
    private static bool isBinaryRepresentationOfNumberPalindrome(int num)  {
        string binary = Convert.ToString(num, 2);
 
        return binary.Equals(String.Join("", binary.Reverse()));
    }
     
    private static bool isPalindrome(int n) {
        int reverse = 0, temp = n;
      
        while (temp != 0) {
            int remainder = temp % 10;
            reverse = (reverse * 10) + remainder;
            temp = temp / 10;
        }
      
        return n == reverse;
    }
  
    public static void Main(string[] args)
    {
        int n = 585; // 1001001001
  
        Console.Write(isPalindrome(n) && isBinaryRepresentationOfNumberPalindrome(n) ? "yes" : "no");
    }
}

yes
