首先准备好分页的T-SQL语句：
1 create proc usp_activityFenYe 2 @pageIndex int, 3 @pageSize int, 4 @pageCount int output 5 as 6 declare @count int 7 begin 8 select @count=COUNT(*) from Activity 9 set @pageCount=CEILING(@count*1.0/@pageSize) 10 select * from(select *,ROW_NUMBER()over(order by activityid) as num from Activity) as t 11 where num between (@pageIndex-1)*@pageSize+1 and @pageIndex*@pageSize 12 order by ActivityID asc 13 end
ADO.NET操作：
(1)DAL：
1 public class ActivityDAL
2 {
3 public List<Activity> GetList(int pageIndex, int pageSize, out int pageCount)
4 {
5 SqlParameter[] pms = new SqlParameter[] {
6 new SqlParameter("@pageIndex",pageIndex),
7 new SqlParameter("@pageSize",pageSize),
8 new SqlParameter("@pageCount",0)
9 };
10 pms[2].Direction = ParameterDirection.Output;
11 List<Activity> list = new List<Activity>();
12 DataTable dt = DBHelper.ExecuteTableSP("usp_activityFenYe", pms);
13 if (dt.Rows.Count > 0)
14 {
15 Activity model = new Activity();
16 foreach (DataRow row in dt.Rows)
17 {
18 model = LoadEntity(row);
19 list.Add(model);
20 }
21 }
22 pageCount = Convert.ToInt32(pms[2].Value);
23 return list;
24 }
25
26 private Activity LoadEntity(DataRow row)
27 {
28 Activity model = new Activity();
29 model.ActivityID = Convert.ToInt32(row["ActivityID"]);
30 model.Name = row["Name"].ToString();
31 return model;
32 }
33 }
(2)BLL：
1 public class ActivityBLL
2 {
3 ActivityDAL dal;
4 public ActivityBLL()
5 {
6 dal = new ActivityDAL();
7 }
8 public List<Activity> GetList(int pageIndex, int pageSize, out int pageCount)
9 {
10 return dal.GetList(pageIndex, pageSize, out pageCount);
11 }
12 }
(3)View：
1 public class ActivityController : Controller
2 {
3 ActivityBLL bll;
4 DBEntities db;//数据上下文
5 public ActivityController()
6 {
7 bll = new ActivityBLL();
8 db = new DBEntities();
9 }
10 public ActionResult Index(int? pageIndex)
11 {
12 //1.ADO.NET
13 int pageSize = 5;
14 int pageCount;
15 List<Model.Activity> list = bll.GetList(pageIndex ?? 1, pageSize, out pageCount);
16 if (Request.IsAjaxRequest())
17 {
18 return Json(list, JsonRequestBehavior.AllowGet);
19 }
20 ViewBag.pageCount = pageCount;//总页数
21
22 //2.EF存储过程
23 ObjectParameter obj = new ObjectParameter("pageCount", typeof(int));//注意：前面不要写@
24 ObjectResult<usp_activityFenYe_Result> result = db.usp_activityFenYe(pageIndex ?? 1, pageSize, obj);//使用之前记得导入存储过程
25 //ViewBag.pageCount = obj.Value;//EF传出的总页数
26
27 //3.另外一种基于EF的方法
28 SqlParameter pCount = new SqlParameter("pageCount", -1);//注意：前面不要写@
29 pCount.Direction = System.Data.ParameterDirection.Output;
30 SqlParameter pIndex = new SqlParameter("@pageIndex", 1);
31 SqlParameter pSize = new SqlParameter("pageSize", 5);
32 List<Models.Activity> data = db.Database.SqlQuery<Models.Activity>("exec usp_activityFenYe @pageIndex,@pageSize,@pageCount output", new object[] { pCount,pIndex,pSize}).ToList();
33 return View(list);
34 }
35 }
(4)Razor：
1 @{
2 Layout = null;
3 }
4 @model IEnumerable<Ado.Net.Model.Activity>
5 <!DOCTYPE html>
6 <html>
7 <head>
8 <meta name="viewport" content="width=device-width" />
9 <title>Index</title>
10 <link href="~/Content/bootstrap.min.css" rel="stylesheet" />
11 <script src="~/Scripts/jquery-1.8.2.min.js"></script>
12 <script>
13 function show(index) {
14 $.getJSON("@Url.Action("Index")", { pageIndex: index }).success(function (data) {
15 var text = "";
16 for (var i = 0; i < data.length; i++) {
17 text += "<tr><td>" + data[i].ActivityID + "</td><td>" + data[i].Name + "</td><td><a href=‘javascript:;‘ onclick=‘del(" + data[i].ActivityID + ")‘>删除</a></td><td><a href=‘javascript:[email protected]("Modify")?id=" + data[i].ActivityID + ")‘>修改</a></td></tr>";
18 }
19 $("#table").html(text);
20 $(".pagination li").removeClass("active").eq(index - 1).addClass("active");
21 })
22 };
23 function del(id) {
24 if (confirm("确定删除")) {
25 $.post("@Url.Action("Del")", { id: id }).success(function (data) {
26 if (data.status == 200)
27 show(1);
28 })
29 }
30 };
31 </script>
32 </head>
33 <body>
34 <div class="container">
35 <table class="table table-striped table-bordered">
36 <thead>
37 <tr>
38 <th>活动ID</th>

40 <th>操作</th>
41 </tr>
42 </thead>
43 <tbody id="table">
44 @foreach (var i in Model)
45 {
46 <tr>
47 <td>@i.ActivityID</td>
48 <td>@i.Name</td>

50 <td><a href="@Url.Action("Modify", new { id = i.ActivityID })">修改</a></td>
51 </tr>
52 }
53 </tbody>
54 </table>
55 <nav>
56 <ul class="pagination pagination-lg">
57 @for (int i = 1; i <= ViewBag.pageCount; i++)
58 {
59 <li @(i == 1 ? "class=active" : "")><a href="javascript:;" onclick="show(@i)">@i</a></li>
60 }
61 </ul>
62 </nav>
63 </div>
64 </body>
