Hello everyone, I am going to share the code sample for the palindrome using c# with console application as given below.
/// <summary>
/// <summary>
/// This is used for check the input string is Palindrome or
not?
/// </summary>
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApplication1
{
   public class IsPalindrome
    {
        static void Main(string[] args)
        {
            string PalindromeStr = string.Empty; 
            Console.WriteLine("Enter a
String");
            string str = Console.ReadLine();
            int m = str.Length;
            for (int n = m - 1; n >= 0; n--)
            {
                PalindromeStr = PalindromeStr +
str[n];
            }
            if (PalindromeStr == str)
            {
                Console.WriteLine(str + "
is a valid palindrome.");
            }
            else
            {
                Console.WriteLine(str + "
is not a valid palindrome.");
            }
            Console.WriteLine(PalindromeStr);
            Console.Read();
        }
    }
}
