文档控件NTKO OFFICE 详细使用说明之预览Excel文件(查看、编辑、保存回服务器)

1、在线预览Excel文件

(1) 运行环境

① 浏览器:支持IE7-IE11(平台版本还支持ChromeFirefox

② IE工具栏-Internet 选项:将www.ntko.com加入到浏览器的可信站点中,不启用保护模式,并将HTTPS验证取消

③ 如果是开发人员首次使用文档控件,需要将控件手动注册控件,获取控件的版本clisid以及版本信息Version(如果程序已经开发完则可以忽略此步骤)

(2) 创建一个加载控件的JS文件,用户只需修改控件版本号Versionclassidcab包路径,以及添加授权即可。具体可访问http://dev.ntko.com:8000/查看

① JS文件代码如下:(-1表示TRUE,0表示FALSE

    //控件初始化完成后再以流的形式加载文件

        TANGER_OCX.Activate(true);
        var range = TANGER_OCX.ActiveDocument.Application.Worksheets("Cover").Range(localName);

    }
</script>

 

Controller代码如下:

 

/// <summary>
        /// 打开文件
        /// </summary>
        /// <returns></returns>
        public ActionResult ReturnFileStream()
        {
            var bytes = Properties.Resources.excel;
            var fileStream = new MemoryStream(bytes);
            return new FileStreamResult(fileStream, "application/xhtml+xml");
        }

        /// <summary>
        /// 保存文件
        /// </summary>
        /// <returns></returns>
        [HttpPost]
        public ActionResult uploadFile()
        {

            var files = Request.Files[0];
            var path = Server.MapPath($"~/{DateTime.Now.ToLongDateString()}.xls");
            FileStream fs = new FileStream(path, FileMode.OpenOrCreate);
            byte[] bytes = new byte[files.InputStream.Length];
            files.InputStream.Read(bytes, 0, bytes.Length);
            fs.Write(bytes, 0, bytes.Length);
            fs.Close();
            return View("Index");
        }
