How I can code in windows form for knapsack prblem?

namespace KnapsackAlgo

    class KnapsackAlgorithm
    {

        public static int KnapSack(int capacity, int[] weight, int[] value, int itemsCount)
        {
            int[,] K = new int[itemsCount + 1, capacity + 1];

            for (int i = 0; i <= itemsCount; ++i)
            {
                for (int w = 0; w <= capacity; ++w)
                {
                    if (i == 0 || w == 0)
                        K[i, w] = 0;
                    else if (weight[i - 1] <= w)
                        K[i, w] = Math.Max(value[i - 1] + K[i - 1, w - weight[i - 1]], K[i - 1, w]);
                    else
                        K[i, w] = K[i - 1, w];
                }
            }

            return K[itemsCount, capacity];
        }

        static void Main(string[] args)
        {

                value[i] = x;

            }

            Console.WriteLine("enter weights of items:");

            {
                int y = int.Parse(Console.ReadLine());
                weight[j] = y;
            }
            int result = KnapSack(capacity, weight, value, itemsCount);
            Console.WriteLine(result);
