Solution 1

try to do this way :

C#

double[] price = new[] { 25.75, 68 };
            double sum = 0;
            for (int i = 0; i < 2; i++)
            {
                sum +=Math.Round(price[i]);
            }

            Console.WriteLine(sum);
            Console.ReadLine();

Solution 2

u can use datatable compute method like below

totalprice= dtproduct.Compute("SUM(Price)", String.Empty).ToString

then assign the value of totalprise to your desiered textbox , but u can only do it , if u have only 2 rows in datatable , if u want to sum on specific columns then there is another way

Thanks
