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.
