Members

Member	Description
BestCompression	The "best" compression, where best means greatest reduction in size of the input data stream. This is also the slowest compression.
BestSpeed	The fastest but least effective compression.
Default	The default compression level, with a good balance of speed and compression efficiency.
Level0	Same as None.
Level1	A synonym for BestSpeed.
Level2	A little slower, but better, than level 1.
Level3	A little slower, but better, than level 2.
Level4	A little slower, but better, than level 3.
Level5	A little slower than level 4, but with better compression.
Level6	A synonym for Default.
Level7	Pretty good compression!
Level8	Better compression than Level7!
Level9	A synonym for BestCompression.
None	None means that the data will be simply stored, with no change at all. If you are producing ZIPs for use on Mac OSX, be aware that archives produced with CompressionLevel.None cannot be opened with the default zip reader. Use a different CompressionLevel.
