            List<FileInfo> files = new List<FileInfo>();
            ///获取文件列表信息
            foreach (var file in Directory.GetFiles(directory))
            {
                files.Add(new FileInfo(file));
            }
            ///查询文件列表信息
            var filevalues = from file in files
                             where file.Extension == ".pdf" && file.Name.IndexOf("报告") > -1
                             orderby file.Name
                             select file;
