String is a Palindrome !

How to check if a string is a palindrome ?
You can change the code a bit to reverse an array

public static bool IsPalindrome(string s)
        {
            int length =s.Length;
            char[] chrArray = s.ToCharArray();
            if (length == 0)
                return false;
            if (length == 1)
                return true;

            int start = 0;
            int end = length - 1;

            while (end > start)
            {
                if (chrArray[start] == chrArray[end])
                {
                    start++;
                    end--;
                }
                else
                {
                    return false;
                }
            }
            return true;
        }
