Syntax
public enum CompressionLevelFields
| Name | 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. |
