在你认为“又来这种问题”的之前，请先阅读以下内容。
我有一个应用程序（ASP.NET MVC 3的Web应用程序），使用DocX库生成DocX格式的Word文件。
该应用程序使用模板并填充所有来自数据库的数据。现在，我想创建该生成的docx文件的PDF版本。
我知道apose.word是一种选择，但对于我来说不是，因为我的预算有限。我必须花费一些金钱的其他库也不可行。
我没有SharePoint服务器，因此Word Automation Services也不是一个选择。
因此，我还剩下2个选项（我知道的），它们都使用iTextSharp。不知道哪一个更好。
有人知道需要多少工作量，哪一种性能更好，是否可能执行吗？
我知道第二个选项的缺点是当我更改模板时，我必须为两个版本都进行更改。
如果您有更好的解决方案（免费的），欢迎分享。
另一个选择，即使它需要一些工作：在服务器上安装OpenOffice，使用UNO库（将它们作为您的应用程序的程序集），您可以直接打开docx文档并将其保存为PDF。
几分钟后我会发布一个例子...
部分示例：
这是我很久以前创建的一个类，用于将文件转换为PDF。
