使用System.IO.Packaging程序生成的ZIP文件 [英] Using System.IO.Packaging to generate a ZIP file

问题描述

我知道DotNetZip或SharpZipLib库的喜欢，通常建议在.NET语言创建ZIP文件（C＃在我的情况），但它不是的不可能的使用 System.IO.Packaging程序来生成一个ZIP文件。我想这可能是不错的尝试，并制定了常规的C＃这能做到这一点，而无需下载任何外部库。有没有人有一种方法或方法将使用一个很好的例子 System.IO.Packaging程序来生成一个ZIP文件？

I know that the likes of the DotNetZip or SharpZipLib libraries are usually recommended for creating ZIP files in a .net language (C# in my case), but it's not impossible to use System.IO.Packaging to generate a ZIP file. I thought it might be nice to try and develop a routine in C# which could do it, without the need to download any external libraries. Does anyone have a good example of a method or methods that will use System.IO.Packaging to generate a ZIP file?
