I did this using ITextSharp-- there are commercial options that may have a good API but this is open source and free, and not hard to use.
我使用ITextSharp做到了这一点——有一些商业选项可能有一个很好的 API，但这是开源和免费的，并且不难使用。
Check out this code, it's one of their code samples -- it's pretty good. It splits a PDF file into two files at the passed-in page number. You can modify it to loop and split page by page.
查看这段代码，这是他们的代码示例之一——非常好。它按照传入的页码将 PDF 文件拆分为两个文件。您可以将其修改为逐页循环和拆分。

Haven't played with it, but you can look at Aspose.Pdf.Kit for .NET and Java. It is commercial so you'll need to pay licensing feeds, but if you need commercial support it might work for you.
还没有玩过，但你可以看看Aspose.Pdf.Kit for .NET 和 Java。它是商业性的，因此您需要支付许可费用，但如果您需要商业支持，它可能对您有用。

Siberix offers a reasonably costed commercial library for creating PDF's on the fly in .NET: http://siberix.comYou can create the PDF's programmatically or through an XML transformation (and a combination of both IIRC).
Siberix 提供了一个成本合理的商业库，用于在 .NET 中即时创建 PDF：http://siberix.com 您可以通过编程方式或通过 XML 转换（以及 IIRC 的组合）创建 PDF。
I've used their library on a couple of projects and have found that not only is their library easy to work with, but their email support is incredible. And the license is quite cheap as well.
我在几个项目中使用了他们的库，发现他们的库不仅易于使用，而且他们的电子邮件支持令人难以置信。而且许可证也很便宜。
