Description
Returns the percentage by which the data has been compressed.
The compression rate is a read-only property. Its value is calculated and updated as data is written to the stream. For example, if a total of 100 raw (uncompressed) bytes have been written to the stream, and only 25 compressed bytes have been written out, then reading the CompressionRate property will return a value of 75.
