            //删除历史数据EXCLE 当天前一天的数据都删除
                var folder = Path.GetDirectoryName(absFilePath);
                var files = Directory.GetFiles(folder);
                foreach (var file in files)
                
                    if (File.GetCreationTime(file) <= DateTime.Now.AddDays(-1))
                    
                        File.Delete(file);
                    
                
                //删除历史数据  删除文件夹，当天以前的文件夹都删除
              var    tempFolder = HttpContext.Current.Server.MapPath("/Upload/TMS/WayBill");  ---服务器的虚拟地址
              //var tempFolder = AppDomain.CurrentDomain.BaseDirectory + "Upload\\Import\\WayBillOther"; ---------本地的时候可以用
                var folders = Directory.GetDirectories(tempFolder);
                foreach (var folderPath in folders)
                
                    DirectoryInfo dInfo = new DirectoryInfo(folderPath);
                    if (dInfo.CreationTime < DateTime.Now.AddDays(-1))
                    
                        Directory.Delete(dInfo.FullName, true);
