the following example msdn shows how use gzipstream class compress , decompress directory of files.

namespace zip {     public class program     {         public static void main()         {             string directorypath = @"c:\users\public\reports";              directoryinfo directoryselected = new directoryinfo(directorypath);              foreach (fileinfo filetocompress in directoryselected.getfiles())             {                 compress(filetocompress);             }              foreach (fileinfo filetodecompress in directoryselected.getfiles("*.gz"))             {                 decompress(filetodecompress);             }         }          public static void compress(fileinfo filetocompress)         {             using (filestream originalfilestream = filetocompress.openread())             {                 if ((file.getattributes(filetocompress.fullname) & fileattributes.hidden) != fileattributes.hidden & filetocompress.extension != ".gz")                 {                     using (filestream compressedfilestream = file.create(filetocompress.fullname + ".gz"))                     {                         using (gzipstream compressionstream = new gzipstream(compressedfilestream, compressionmode.compress))                         {                             originalfilestream.copyto(compressionstream);                             console.writeline("compressed {0} {1} {2} bytes.",                                 filetocompress.name, filetocompress.length.tostring(), compressedfilestream.length.tostring());                         }                     }                 }             }         }          public static void decompress(fileinfo filetodecompress)         {             using (filestream originalfilestream = filetodecompress.openread())             {                 string currentfilename = filetodecompress.fullname;                 string newfilename = currentfilename.remove(currentfilename.length - filetodecompress.extension.length);                  using (filestream decompressedfilestream = file.create(newfilename))                 {                     using (gzipstream decompressionstream = new gzipstream(originalfilestream, compressionmode.decompress))                     {                         decompressionstream.copyto(decompressedfilestream);                         console.writeline("decompressed: {0}", filetodecompress.name);                     }                 }             }         }     } }
