在日本做色情网站/求职seo推荐

昨天看了一会linq的书.今天哪来练练手.写了个简单的linq分页.在这里拿出来与大家共享一下.适合小数据型分页.因为他是先读取完全数据,然后在进行分页.

好了直接贴出代码

首页新建一个aspx页面

然后在后台aspx.cs文件中

 1  protected void Page_Load(object sender, EventArgs e)
 2         {
 3             if (!IsPostBack)
 4             {
 5                 int CurPage = 1;
 6                 int PageSize = 5;
 7                 int.TryParse(Request["CurPage"], out CurPage);
 8                 if (CurPage == 0)
 9                     CurPage = 1;
10                 //获取总数据集合
11                 IList<ContentsModel> objs = new List<ContentsModel>();
12                 objs = Contents.GetAllContents();
13                 //绑定数据显示控件
14                 GridView1.DataSource = QueryByPage(PageSize, CurPage, objs);
15                 GridView1.DataBind();
16                 //获取分页目录
17                 this.Label1.Text = GetQueryPagesMenu(PageSize, objs);
18             }
19         }
20         /// <summary>
21         /// 输入分页字符页码
22         /// </summary>
23         /// <param name="PageSize"></param>
24         /// <param name="objs"></param>
25         /// <returns></returns>
26         protected string GetQueryPagesMenu(int PageSize, IList<ContentsModel> objs)
27         {
28             int Count;
29             var db = objs;
30             var query = from cms_contents in db select cms_contents;
31             Count = (query.Count() / PageSize + 1);//不足一页按一页算
32             string PageMenu = "";
33             //拼接分页目录
34             for (int i = 1; i <= Count; i++)
35             {
36                 PageMenu += "<a href='?CurPage=" + i.ToString() + "'>" + i.ToString() + "</a>&nbsp;|&nbsp;";
37             }
38             return PageMenu;
39         }
40         /// <summary>
41         /// 获取分页后的数据集
42         /// </summary>
43         /// <param name="PageSize">每页显示的记录数</param>
44         /// <param name="CurPage">页数</param>
45         /// <param name="objs">数据总集合</param>
46         /// <returns></returns>
47         protected List<ContentsModel> QueryByPage(int PageSize, int CurPage, IList<ContentsModel> objs)
48         {
49             var query = from cms_contents in objs select cms_contents;
50             return query.Take(PageSize * CurPage).Skip(PageSize * (CurPage - 1)).ToList();
