C# Class SilverlightMappingToolBasic.CompendiumMapProcessor.ZipFile

Easy unzipping of ZIP files.

Silverlight has built-in capabilities to extract files from a zip file. However, you need to know up front what files are in the zip to unzip them. This utility parses the headers and gives you access to the file names embedded in the zip. Furthermore, Silverlight unzipping has some limitations and doesn't support zip files where the file sizes and CRC is placed after the file data. This utility detects this case and re-arranges the bytes so Silverlight can read and uncompress the files.
