Sum of consecutive squares (Palindrome) using c#

The palindromic number 595 is interesting because it can be written as the sum of consecutive squares: 6² + 7² + 8² + 9² + 10² + 11² + 12^{2
Find the sum of all the numbers less than limit that are both palindromic and can be written as the sum of consecutive squares}

            Console.WriteLine("Consecutive sum of squares palindrome from 1 to " + limit);

            for (int i = 1; i <= sqrtLimit; i++)

                //Here for example if i is 1 then j must starts from 2
               //Because we summed the value of squares like 1^1 * 2^2
