How to Uncompress Gzip File in Windows Mobile 2005 with C#

Every day I was programming a module to get of a FTP File Server a Gzip Compressed File of a sqlite database file that have 10Mb size and compressed have 2.5Mb size.
For make it this I did the following:
Operating System:
Server: Ubuntu Linux Server
Client: Windows Mobile 2005
Hardware:
MC70 Symbol Technologies Terminal
HP iPaq RX3715
Network Connections:
MC70:GPRS-Telcel
iPaq RX3715: WiFi 802.11b
FTP Server:
PureFTPd
Programming language:
C#
Library to uncompress:
ZlibCE
Linux Application to compress:
gzip
Problem:
My problem was than I had to get a SQLite Database File (near of one hundred thousands records in thirtyfive tables) of a FTP File Server by mean GPRS to one hand held MC70 of Symbol Technologies.
The GPRS connection in México is offered by Telcel & Movistar, but at south of Veracruz State the GPRS connection only is available by Telcel. The GPRS Provider in México offer plans of 50Mb BandWidth for $ 55.00 dlls + 15 percent of tax, then to download my DataBase File of 10Mb file size is the 20% of BandWidth Limit, this indicate tha only I could to download five times to the month. To resolve this Problem that represent money for the company, I did use zlib, an Open Source library compression. Using Zlib with gzip in Linux I can to diminish of 10 Mb to 2.5Mb file size, and in the terminal I can download this file by mean of OpenNetCF.Net.Ftp and Uncompress the file with ZlibCE Library, therefore I saving seventy five percent of bandwith.
In linux you can to create a GZIP File with the following command:

gzip -c MyFile.txt > MyFile.gz

 

And you can to add more files to your gzip file created :

gzip -c MyOtherFile.txt >> MyFile.gz

 

And you can to develop a program in C# to uncompress the Gzip File

using System;

using System.Text;

using System.IO;

using OpenNETCF.Compression;

namespace zlibSampleCS

{

    class Program

    {

        static void Main(string[] args)

        {

            UncompressGZFile(@"\Application\zlibce.gz", @"\Application\zlibce.dll");

        }

        private static void UncompressGZFile(string source, string destiny)

        {

            try

            {

                GZStream stm = GZStream.OpenRead(File.OpenRead(source));

                Stream stmOut = File.Create(destiny);

                byte[] buf = new byte[8192];

                int cb = buf.Length;

                while ((cb = stm.Read(buf, 0, cb)) != 0)

                {

                    stmOut.Write(buf, 0, cb);

                    cb = buf.Length;

                }

                stm.Close();

                stmOut.Close();

            }

            catch (Exception ex)

            {

            }

        }

    }

}

You will need zlibce.dll installed in the directory of your application and also OpenNetcf.Compression.ZlibCE.dll, this dynamic libraries you can get from http://OpenNetCF.com/zlibce/
If You can to get more info you should to visit OpenNetCF Site[http://www.opennetcf.org]
