     private void  TestPostData()
        {
            string all = "";
            List<int> listTimeCard = new List<int>() {1,4,3,4,5,76,4,3,2,3,5 ,766,7};
            int pageSize = 2; int pageNum = 0;
            
            while (pageNum*pageSize <listTimeCard.Count())
            {
                var batchData = listTimeCard.Skip(pageSize *pageNum ).Take(pageSize);
                string s = JsonConvert.SerializeObject(batchData);
                all += s;
                Debug.WriteLine(""+s);
                pageNum++;
            }
        }

　　

 

其他例子：

class Program   
  {   
      static int Main()   
      {   
          //每页条数   
          const int pageSize = 2;   
          //页码 0也就是第一条 
          int pageNum = 0;   
   
          //源数据   
          string[] names = { "刘一","陈二","张三","李四","王五","赵六","孙七","周八","吴九" };
   　　　　
          while (pageNum * pageSize < names.Length)   
          {   
              //分页   
              var query = names.Skip(pageNum * pageSize).Take(pageSize);   
              Console.WriteLine("输出第{0}页记录", pageNum + 1);   
              //输出每页内容   
              foreach (var q in query)   
              {   
                  Console.WriteLine(q);   
              }   
              pageNum++;   
          }   
   
          Console.ReadKey();   
   
          return 0;   
      }   
  }
