C# Класс ICSharpCode.SharpZipLib.Zip.ZipExtraData

A class to handle the extra data field for Zip entries

Extra data contains 0 or more values each prefixed by a header tag and length. They contain zero or more bytes of actual data. The data is held internally using a copy on write strategy. This is more efficient but means that for extra data created by passing in data can have the values modified by the caller in some circumstances.
