请教个创建zip文件的问题
请教个创建zip文件的问题我在网上找了一下，始终没有找到一个合适的创建zip文件的方法。
使用ZipPackage类产生的文件包含几个其他的文件，感觉不舒服，使用GZipStream创建的好像也不是标准的zip文件，使用windows自身的解压功能好像解压不了。
不知道哪位高手能够指教一下，我就是想能够自己将两个文件包在一个标准的zip文件中。 --------------------编程问答-------------------- 使用 ICSharpCode.SharpZipLib

} --------------------编程问答-------------------- 这篇文章里介绍了如何解压，你看看能不能参照着写成压缩的代码:
C# Use Zip Archives without External Libraries
http://www.codeproject.com/Articles/209731/Csharp-use-Zip-archives-without-external-libraries
下面的来自上面文章:
To access simple Zip archives with ZipPackage fails because the content is checked for Package conventions.
For example, there has to be a file [Content_Types].xml in the root and only files with specified extensions are accessible. Filenames with special characters and spaces are not allowed and the access time is not the best because of the additional Package link logic.
However, the assembly WindowsBase.DLL is preinstalled and the generic Zip implementation is inside. The only problem is that the generic Zip classes are not public and visible for the programmers. But there is a simple way to get access to this hidden API and I wrote a small wrapper class for this. --------------------编程问答-------------------- 那你只能 反编译 ICSharpCode.SharpZipLib
然后自己创建 类了
--------------------编程问答--------------------
用J#调用java的zip相关内容，还可以添加crc232校验呢，.net自身的好像没有校验这块的 --------------------编程问答-------------------- 高手啊
--------------------编程问答--------------------
版主说的那个相当好用，而且是开源的，为什么不用？
--------------------编程问答--------------------
用LS说的第三方开源库就可以（兼容NET2.0）如果是Net3.0以上平台，可以引用WindowsBase.dll
using System.IO.Packaging;
LZ可以搜索一下
补充：.NET技术 , VB.NET
