C# 4.0 和 Word 2007 自动化

Question

我正在创建一个应用程序，该应用程序从 Oracle 数据库获取数千个 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、多任务处理以及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，我的第一个方法是使用它（事实是我的客户要求使用它）。但我对 c# (.Net 4.0) 和 word 2007 之间的交互感到疯狂。我已经尝试过 SaveAs 和 ExportAsFixedFormat。两者都工作正常，但是当我尝试关闭该单词时...我收到一个错误（弹出窗口说该单词发现问题并将被关闭）。然后我尝试在退出应用程序之前包含此内容：

wordApplication.NormalTemplate.Saved = true;

但它仍然抛出错误。我无法在没有错误的情况下转换一百多个文档。您知道在不使用办公自动化的情况下实现这种转换的一些方法吗？或者另一方面，您知道如何通过办公自动化来无误地进行这种转换吗？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）

我们使用名为 Aspose 的商业产品来进行所有 Office 集成（因为它实际上不需要 Office，速度非常快，并且不是 Interop）。我不能 100% 确定是否支持您的具体场景，但他们的网站上有很多示例，如果您的项目支持购买几个许可证，这可以让您的生活变得更轻松。
