(Mono C#) GZip Create / Extract .gz FileDemonstrates how to compress a file to create a .gz (GZip) file. Note: The .gz file format is a compressed file format. It contains a single file. The .gz file format is not an archive format (i.e. it does not contain a collection of files/directories such as with the .zip, .rar, or .tar file formats). GZip is often combined with TAR to create a .tgz (or .tar.gz). Note: It is possible for a .gz to contain more than one file, but this is very uncommon.
// This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Gzip gzip = new Chilkat.Gzip(); // File-to-file GZip: // Compress "hamlet.xml" to create "hamlet.xml.gz" bool success = gzip.CompressFile("hamlet.xml","hamlet.xml.gz"); if (success != true) { Debug.WriteLine(gzip.LastErrorText); return; } // File-to-file ungzip // Decompress "hamlet.xml.gz" to create "hamletOut.xml" success = gzip.UncompressFile("hamlet.xml.gz","hamletOut.xml"); if (success != true) { Debug.WriteLine(gzip.LastErrorText); return; } // File-to-string ungzip // Decompress the contents of a .gz directly to a string variable: // The 2nd argument indicates the charset of the character // data after it is decompressed. string xmlStr; xmlStr = gzip.UncompressFileToString("hamlet.xml.gz","utf-8"); if (success != true) { Debug.WriteLine(gzip.LastErrorText); return; } Debug.WriteLine(xmlStr); // The Chilkat GZip API provides much more flexibility than shown // here.
