Specifies values that indicate whether a compression operation emphasizes speed or compression size.
Assembly: System (in System.dll)
|The compression operation should complete as quickly as possible, even if the resulting file is not optimally compressed.|
|No compression should be performed on the file.|
|The compression operation should be optimally compressed, even if the operation takes a longer time to complete.|
Compression operations usually involve a tradeoff between the speed and the effectiveness of compression. You use the enumeration to indicate which factor is more important in your development scenario: the time to complete the compression operation or the size of the compressed file. These values do not correspond to specific compression levels; the object that implements compression determines how to handle them.
