　　ASP.NET MVC中進行分頁的方式有多種，在NuGet上有提供使用PagedList、PagedList.Mvc進行分頁。

　　1. 通過NuGet引用PagedList.Mvc

　　在安裝引用PagedList.Mvc的同時會安裝引用PagedList。

　　2. PagedList.Mvc基本使用

　　ProvinceController.cs：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

using MvcExample.Models;

using PagedList;

namespace MvcExample.Controllers
{
    public class ProvinceController : Controller
    {
        private MvcExampleContext ctx = new MvcExampleContext();

        public ActionResult Index(int page = 1)
        {
            return View(ctx.Provinces.OrderBy(p => p.ProvinceID).ToPagedList(page, 10));
        }

        protected override void Dispose(bool disposing)
        {
            ctx.Dispose();
            base.Dispose(disposing);
        }
    }
}

　　Index.cshtml：

@model PagedList.IPagedList<MvcExample.Models.Province>
@using PagedList.Mvc;
@{
    Layout = null;
}
<!DOCTYPE html>
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
    <style type="text/css">
        ul.pagination
        {
            margin: 0;
        }
        .pagination li
        {
            list-style-type: none;
            float: left;
            min-width: 15px;
        }
    </style>
</head>
<body>
    <table>
        <tr>
            <th>
                省份ID
            </th>
            <th>
                省份編號
            </th>
            <th>
                省份名稱
            </th>
        </tr>
        @foreach (var item in Model)
        {
            <tr>
                <td>
                    @Html.DisplayFor(modelItem => item.ProvinceID)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.ProvinceNo)
                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.ProvinceName)
                </td>
            </tr>
        }
    </table>
    @Html.PagedListPager(Model, page => Url.Action("Index", new { page }))
</body>
</html>

　　執行效果：

　　引入PagedList.Mvc分頁之後生成的分頁Html程式碼：

 　　分頁執行的SQL語句：

SELECT TOP (10) 
    [Extent1].[ProvinceID] AS [ProvinceID], 
    [Extent1].[ProvinceNo] AS [ProvinceNo], 
    [Extent1].[ProvinceName] AS [ProvinceName]
    FROM ( SELECT [Extent1].[ProvinceID] AS [ProvinceID], [Extent1].[ProvinceNo] AS [ProvinceNo], [Extent1].[ProvinceName] AS [ProvinceName], row_number() OVER (ORDER BY [Extent1].[ProvinceID] ASC) AS [row_number]
        FROM [dbo].[Province] AS [Extent1]
    )  AS [Extent1]
    WHERE [Extent1].[row_number] > 10
    ORDER BY [Extent1].[ProvinceID] ASC
