我如何ZIP在C＃中的文件，不使用第三方的API？ [英] How do I ZIP a file in C#, using no 3rd-party APIs?

问题描述

我是pretty肯定这是不是一个重复这样我承担只需一分钟。

I'm pretty sure this is not a duplicate so bear with me for just a minute.

我如何编程（C＃）ZIP（在Windows）的文件，而无需使用任何第三方库？我需要一个本地的Windows电话或类似的东西;我真的不喜欢，启动过程的想法，但我会如果我绝对要。一个PInovke调用会好得多。

How can I programatically (C#) ZIP a file (in Windows) without using any third party libraries? I need a native windows call or something like that; I really dislike the idea of starting a process, but I will if I absolutely have to. A PInovke call would be much better.

如果做不到这一点，让我告诉你我真正想要完成：我需要让用户下载的文档集合在一个请求的能力。如何做到这一点任何想法？

Failing that, let me tell you what I'm really trying to accomplish: I need the ability to let a user download a collection of documents in a single request. Any ideas on how to accomplish this?

推荐答案

您使用.NET 3.5？你可以使用<$c$c>ZipPackage类和相关的类。它不是因为它想要一个MIME类型添加的每个文件压缩和解只是一个文件列表了。它可以做你想做的。

Are you using .NET 3.5? You could use the ZipPackage class and related classes. Its more than just zipping up a file list because it wants a MIME type for each file you add. It might do what you want.

我目前使用这些类类似的问题存档几个相关的文件到下载一个文件。我们使用文件扩展名来下载文件与我们的桌面应用程序关联。我们遇到了一个小问题是，它不可能只使用第三方工具，如7-ZIP创建的zip文件，因为客户端code不能打开它 - ZipPackage添加描述一个隐藏的文件每个组件文件的内容类型，如果该内容类型文件丢失无法打开zip文件。

I'm currently using these classes for a similar problem to archive several related files into a single file for download. We use a file extension to associate the download file with our desktop app. One small problem we ran into was that its not possible to just use a third-party tool like 7-zip to create the zip files because the client side code can't open it -- ZipPackage adds a hidden file describing the content type of each component file and cannot open a zip file if that content type file is missing.
