在.net中，除了人手动写分页类之外，微软还提供了官方的分页，分页工具类包括PagedList和PagerExtension，先来看看PagedList类里面是怎么写的：

PagedList

using System;using System.Collections.Generic;using System.Linq;namespace System.Web.Mvc{    public class PagedList<T> : List<T>    {        /// <summary>        /// 页索引        /// </summary>        public int PageIndex { get; private set; }        /// <summary>        /// 页大小        /// </summary>        public int PageSize { get; private set; }        /// <summary>        /// 总数据条数        /// </summary>        public int TotalCount { get; private set; }        /// <summary>        /// 总页数        /// </summary>        public int TotalPages { get; private set; }        /// <summary>        /// 数据信息        /// </summary>      //  public List<T> Source { get; private set; }        public  PagedList(List<T> source, int pageIndex, int pageSize, int totalCount)        {            PageIndex = pageIndex;            PageSize = pageSize;            TotalCount = totalCount;            TotalPages = (int)Math.Ceiling(TotalCount / (double)PageSize);            this.AddRange( source.Take(source.Count));        }        public  PagedList()        {}        /// <summary>        /// 是否包含上一页        /// </summary>        public bool HasPreviousPage        {            get            {                return (PageIndex > 1);            }        }        public bool HasNextPage        {            get            {                return (PageIndex  < TotalPages);            }        }    }}
