推荐答案

愿这个帮助你

你应该在最后返回int

You should return int at the end

 private static int Abc()
        {
            int intVal = 0;
            List<int> result = new List<int>();

            byte[] numbers = GetValue();
            string selectedItems = "";
            int j = 0;
            for (int i = 0; i < 18; i++)
            {
                j++;
                selectedItems += numbers[i];
                if (j == 3)
                {
                    result.Add(getDecimal(selectedItems));
                    j = 0;
                    selectedItems = "";
                }
            }
            Console.WriteLine();
            Console.WriteLine("Result is:");

            foreach (var item in result)
            {
                Console.Write(item);
            }
            Console.ReadLine();
            return intVal;
        }

或使用void返回任何内容

or use void to return nothing as

private static void Abc()
