ActivePDF - $400. I think they use Office interop on the server
Office Interop - Free, but not supported by M$ and ... just don't.
Open Office Interop - Also free. Also scary.
Prices in US$ are current as of January, 2014
What is this interop of which you speak?
Where you install Word or something on the server, include the DLL in your project as a reference and then call methods. Problem is these libraries were not written for multi-user/server/web environments. Almost 100% guaranteed to give you errors.
您正在翻译的 Office 文档的业务案例/数量是多少？这是一个将有数十万用户同时访问 Web 服务器的 Web 应用程序，还是您可以使用批处理方式或限制用户数量？
您希望 PDF 达到什么质量级别？打印质量还是网络质量？
Two questions come to mind:
What is the business case/quantity of Office documents you are translating? Is this a web app that will have hundreds of thousands of users hitting the web server simultaneously, or are you OK with a batch style or to throttle the number of users?
What level of quality do you want the PDF at? Print-quality, or web?

几个选项
以美元为单位的价格是截至 2014 年 1 月的最新价格
您所说的互操作是什么？
在服务器上安装 Word 或其他东西的地方，将 DLL 包含在项目中作为引用，然后调用方法。问题是这些库不是为多用户/服务器/Web 环境编写的。几乎 100% 保证会给你错误。
