    [WebMethod]
    public string HelloWorld()

    }
    [WebMethod]
    public List GetListAjax(int pagesize,int pageindex)
    {
      BLL.T_News1 bnews = new BLL.T_News1();
      DataTable dt = bnews.GetListDataTable(pagesize,pageindex);
      List list = new List();
      int Id;
      string newstitle = "";
      string newscontent = "";
      DateTime createtime;
      for (int i = 0; i < dt.Rows.Count; i++)
      {
 Id = Convert.ToInt32(dt.Rows[i]["Id"]);
 newstitle = dt.Rows[i]["NewsTitle"].ToString();
 newscontent = dt.Rows[i]["NewsContent"].ToString();
 createtime = Convert.ToDateTime(dt.Rows[i]["CreateTime"]);
 Model.T_News1 news = new Model.T_News1()
 {


   Id = Id,
   NewsTitle = newstitle,
   NewsContent = newscontent,
   CreateTime = createtime
 };
 list.Add(news);
      }
      return list;
 
    }
    [WebMethod]
    public int GetLastPageindex(int pagesize)
    {
      BLL.T_News1 bnews = new BLL.T_News1();
      int totalcount = bnews.GetRecordCount("");
      if (totalcount % pagesize == 0)
      {
 return totalcount / pagesize;
      }
      else
      {
 return totalcount / pagesize + 1;
      }
    }


  }
}

以上就是ajax无刷新分页实现的关键代码，希望对大家的学习有所帮助。
