According to Wikipedia WinZip uses .zipx as extension for Zip archives that use compression methods newer than deflate. Deflate is perhaps the minimum standard of Zip which everyone can compress or extract but newer algorithms like bzip2, LZMA or PPMd+ are also defined by the standard.
As for libraries which are able to handle newer compression algorithms you may have luck with SharpZipLib which implements at least bzip2 compression. There is also DotNetZip but it seems to be a little low on newer features.
As Johannes Rossel mentioned SharpZipLib is a decent compression library written in C# and has source code available. This library is used in various projects as well and seems to have decent support. The only negative aspect is that I don't think they currently support WinZip's new zipx format. In fact I haven't found any other application or library that currently supports this new format other than WinZip. If you need a library for their new format probably the first place to start checking is with the WinZip support department to see if they have a native library available that could be wrapped or some specifications on the new format. If this file format is a closed spec then unfortunately you may not have many options.

我建议的一件事就是看这里。
看来他们对开发商开放。

One thing I would suggest is looking here.
it seems they are open to developers.

根据 Wikipedia WinZip 使用
.zipx作为使用比 deflate 更新的压缩方法的 Zip 存档的扩展名。 Deflate 可能是 Zip 的最低标准，每个人都可以压缩或提取，但较新的算法如 bzip2， LZMA 或 PPMd+ 也由标准<定义/a>.至于能够处理较新压缩算法的库，您可能会幸运地使用 SharpZipLib ，它实现了至少 bzip2 压缩。 还有 DotNetZip 但它的新功能似乎有点少。

正如 Johannes Rossel 提到的 SharpZipLib 是一个用 C# 编写的不错的压缩库，并且有可用的源代码。 该库也用于各种项目，并且似乎有不错的支持。 唯一的缺点是我认为它们目前不支持 WinZip 的新 zipx 格式。 事实上，除了 WinZip 之外，目前我还没有发现任何其他应用程序或库支持这种新格式。 如果您需要新格式的库，可能首先要开始检查的是 WinZip 支持部门，看看他们是否有可以包装的可用本机库或新格式的一些规范。 如果此文件格式是封闭规范，那么不幸的是您可能没有太多选择。
