    class Program

            int roleId = YOUR_ROLE_ID;

            // 文件ID

            // 连接到NetSuite系统
            NetSuiteService service = new NetSuiteService();
            service.Timeout = 10000;
            service.CookieContainer = new CookieContainer();
            service.login(account, email, password, roleId);

            // 创建文件下载请求对象
            FileDownload fileDownload = new FileDownload();
            fileDownload.file = new RecordRef();
            fileDownload.file.internalId = fileId;

            // 调用NetSuite的Web服务接口下载文件
            File file = service.download(fileDownload);

            // 获取文件的下载链接
            string fileUrl = file.url;

            // 发送HTTP GET请求下载文件
            using (HttpClient client = new HttpClient())
            {
                HttpResponseMessage response = await client.GetAsync(fileUrl);
                response.EnsureSuccessStatusCode();

                // 保存文件到本地
                using (FileStream fileStream = new FileStream("downloaded_file.txt", FileMode.Create, FileAccess.Write))
                {
                    await response.Content.CopyToAsync(fileStream);
                }
            }

            Console.WriteLine("文件下载完成！");
        }
    }
}
