This C# program decompresses a GZIP byte array using GZipStream. You do not need a MemoryStream because bytes already has the data to compress. te() should not be used. When creating the zipStream the output. Compressing data is a great way to reduce its size. This helps us reduce storage requirements as well as the bandwidth and latency of network.

The gzip data format uses the same algorithm as the DeflateStream class, but can be extended to use other compression formats.

Reads a vzipstream from the stream and advances the position within the stream by one byte, or returns -1 if at the end of the stream. I highly recommend you using MemoryStream as a data source over the raw byte[] because Stream has a lot more versatility and application FileStreamNetworkStreamCryptoStreametc.
