怎样把一个文件夹的图片，读出绑定到datalist上？

[人生就是赌]

读取文件中的图片，生成一个datatable，然后绑定
例如：

/// <summary>
        /// 获取生成的文件信息，生成一个datatable
        /// </summary>
        /// <param name="pathPrefixName">文件夹的前缀，例如：xml或marc或excel</param>
        /// <param name="provinceid">省份编号</param>
        /// <param name="schoolid">学校编号</param>
        /// <param name="createTime">文件创建的开始时间</param>
        /// <param name="fileExtension">文件的后缀名，例如：ISO,TXT,XLS</param>
        /// <returns></returns>
        public static DataTable GetFileInfo(string pathPrefixName, int provinceid, int schoolid, DateTime createTime, string fileExtension)
        {
            string path = pathPrefixName + "/" + provinceid.ToString() + "/" + schoolid.ToString() + "/";
            string fileName = string.Empty;//当前文件名称
            string downLoadPath = string.Empty;//当前文件的下载路径
            DirectoryInfo directoryinfo = new DirectoryInfo(Utility.ConvertToPhysicalPath(path));
            fileExtension = "*." + fileExtension;
            FileInfo[] fileinfo = directoryinfo.GetFiles(fileExtension);
            int fileCount = fileinfo.Length;
            DataTable dt = new DataTable();
            if (fileCount != 0)
            {
                dt.Columns.Add("FileName", typeof(System.String));
                dt.Columns.Add("CreateTime", typeof(System.DateTime));
                dt.Columns.Add("FileLength", typeof(System.String));
                dt.Columns.Add("FilePath", typeof(System.String));
                for (int i = 0; i < fileCount; i++)
                {
                    if (fileinfo[i].LastWriteTime >= createTime)
                    {
                        fileName = fileinfo[i].Name;
                        downLoadPath = Utility.UserDefinedPath(2) + "/DownLoad.aspx?prefixname=" + pathPrefixName + "&filename=" + HttpUtility.UrlEncode(fileName);
                        DataRow dr = dt.NewRow();
                        int fileLength = int.Parse(fileinfo[i].Length.ToString()) / 1024;
                        dr[0] = fileName;
                        dr[1] = fileinfo[i].LastWriteTime;
                        dr[2] = fileLength.ToString(); ;
                        dr[3] = downLoadPath;
                        dt.Rows.Add(dr);
                    }
                }
            }
            return dt;
        }

读取文件夹下的所有文件，生成一个数据表也就是datatable然后绑定就可以了
