C# Class NetWrok.HTTP.Zlib.CrcCalculatorStream

A Stream that calculates a CRC32 (a checksum) on all bytes read, or on all bytes written.

This class can be used to verify the CRC of a ZipEntry when reading from a stream, or to calculate a CRC when writing to a stream. The stream should be used to either read, or write, but not both. If you intermix reads and writes, the results are not defined.

This class is intended primarily for use internally by the DotNetZip library.
