I'm new to c# and programming in general. I've started to create my own powerpoint plugin. I've got it to where a user can browse for a zip file but now I need to know - How do I parse information from a file within that zip or compound file in c#?

Do I have to use a library? If so how do I go about that?

As others have mentioned, the System.IO.Compression namespace has the ZipFile class for creating/extracting zip files. However, they are only available in .NET 4.5 however, which is currently only available as part of the Visual Studio 2012 RC.

See System.IO.Compression in:

Up until this point, the de-facto standard for working with zip files in .NET has been the DotNetZip Library. It is available under the open-source MS-PL license.

To work with ZIP-files in general, use the ZipArchive class that represents a ZIP file, or the members of the static ZipFile class to work with ZIP files, and use the DeflateStream class to read the contents of a compressed file.

To easily read the contents of a binary file, use the BinaryReader class. Otherwise, use the StreamReader class for text files.
