压缩文件中的内容

Question

how to use zippackage class to know about the content in .zip file? for ex to know the type of file inside this zip file.

Answer 1

Once you open the .zip file, you can use the GetParts method to get a collection of all the files inside the .zip. See the PackagePart class.

Answer 2

http://sharpdevelop.net/OpenSource/SharpZipLib/ is a good zip library for CSharp.

Although, you might just want to use something like the DeflateStream class (http://msdn.microsoft.com/en-us/library/system.io.compression.deflatestream.aspx) which provides a compressed stream and doesn't require dealing with the complexities of an archive that handles multiple files.
