C# 分批处理代码完整实现

 class Program
    {
        static void Main(string[] args)
        {
            List<string> ids = new List<string>
            {
                "1",
                "2",
                "3",
                "4",
                "5",
                "6",
                "7",
                "8"
            };
            int count = Math.Min(ids.Count, 2);//每批获取的多少条
            int len = ids.Count;//数据总条数
            int size = len % count;//需要分几次获取
            if (size == 0)
            {
                size = len / count;
            }
            else
            {
                size = (len / count) + 1;
            }
            Console.WriteLine($"每批取两条需要{size}批");
            for (int i = 0; i < size; i++)
            {
                int fromIndex = i * count;//从哪儿开始
                //int toIndex = Math.Min(fromIndex + count, len);//到哪儿结束
                List<string> needData = ids.Skip(fromIndex).Take(count).ToList();
                Console.WriteLine($"第{i+1}批：" + string.Join("','", needData));
            }
            Console.ReadKey();
        }
    }
