The compression functionality in DeflateStream and GZipStream is exposed as a stream. Data is read on a byte-by-byte basis, so it is not possible to perform multiple passes to determine the best method for compressing entire files or large blocks of data. The DeflateStream and GZipStream classes are best used on uncompressed sources of data. System.IO.Compression.DeflateStream doesn't add any extra data, it outputs a raw deflate stream with no header/metadata. I actually had to add the ZLib header to the stream.

If no further action occurs, the stream appears as a valid, empty, compressed file. Using the DeflateStream class to compress a file larger than 4 GB raises an exception.
