每隔三个C#遍历

        static void Main(string[] args)
        {
            List<int> lis = new List<int>() {1,2,3,4,5,6,7,8, };
            int total = lis.Count;
            int rows = (int)Math.Ceiling(total / 3.0);
            for (int i = 0; i < rows; i++)
            {
                var rowList = lis.Skip(i * 3).Take(3);
                foreach (var item in rowList)
                {
                    Console.Write(item+" ");
                }
                Console.WriteLine();
            }
            Console.Read();
        }
