我正在创建一个应用程序，它从 Oracle 数据库中获取数千个 word 文档，需要将它们转换为 pdf 并将它们发送回数据库。我已经启动并运行了所有支持机制（数据库交互、多任务处理和可插入的数据库和配置方法）。尽管有关于在服务器端使用办公自动化的所有警告，但我的第一个方法是使用它（事实是我的客户要求使用它）。但是我对 c# (.Net 4.0) 和 word 2007 之间的交互感到很生气。我已经尝试过 SaveAs 和 ExportAsFixedFormat。两者都工作得很好，但是当我尝试关闭这个词时......我得到了一个错误（弹出窗口说那个词发现了一个问题并将被关闭）。然后我尝试在退出应用程序之前将其包含在内：
wordApplication.NormalTemplate.Saved = true;
但它仍然抛出错误。我无法转换超过一百个文档而不会出错。你知道在不使用办公自动化的情况下实现这种转换的方法吗？或者另一方面，您知道如何通过办公自动化进行这种转换而不会出错吗？任何帮助将不胜感激。
编辑：Otaku，这是我正在使用的代码示例（警告！提前测试代码）
