C# GZIPSTREAM PDF

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 following example initializes a new instance of the GZipStream class with mode set to Compress. By wrapping the write operation in a using block by itself, we ensure that the data is flushed.

The GZipStream effectively wraps the output stream. In the code above, we are using a memory stream as our underlying output stream. It creates a Gzipstreak, and then saves the object as compressed file on my hard drive, but the saved file is always 0 bytes.
