先建立一个FileListPager.cs类：
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;using System.ComponentModel;namespace FileCollectionSystem.DataFetch{    /// <summary>    /// 文件列表分页    /// </summary>    public class FileListPager<T>    {        public List<T> AllFiles        {            get;            set;        }        /// <summary>        /// 总页数        /// </summary>        public int TotalPage        {            get;            set;        }        /// <summary>        /// 当前页        /// </summary>        public int CurPage        {            get;            set;        }        /// <summary>        /// 显示记录数        /// </summary>        [DefaultValue(5)]        public int PageSize        {            get;            set;        }        public FileListPager(List<T> lstFile)            : this(lstFile, 5)        {        }        public FileListPager(List<T> lstFile, int iPageSize)        {            if (lstFile == null || lstFile.Count == 0) return;            AllFiles = lstFile;            if (iPageSize <= 0)                 PageSize = 5;            else                 PageSize = iPageSize;            TotalPage =                (AllFiles.Count / PageSize) + ((AllFiles.Count % PageSize == 0) ? 0 : 1);        }        /// <summary>        /// 根据页数获取文件        /// </summary>        /// <param name="iPage">页数</param>        /// <returns></returns>        public List<T> GetFileList(int iPage)        {            try            {                   if (AllFiles == null || AllFiles.Count == 0)                     return new List<T>();                if (iPage <= 0) iPage = 1;                else if (iPage > TotalPage) iPage = TotalPage;                int iStart = (iPage - 1) * PageSize;                int iEnd = iStart + (PageSize - 1);                List<T> lstResult = new List<T>();                for (int i = iStart; i <= iEnd; i++)                {                    if (i >= 0 && i < AllFiles.Count)                        lstResult.Add(AllFiles[i]);                }                CurPage = iPage;                return lstResult;            }            catch (Exception ex)            {                SysLogManagement.LogManagement.Logger.WriteError("GetFileList", ex);                return null;            }        }    }}
后来直接拿来调用就可以了。
