Question

I want to zip one “CSV” file in to Zip file using C#.Net. Below i have written some code for create Zip file , using this code i am able to create zip file but after creating “Data1.zip” file extract manually means extracted file extension should be “.csv” but it is not coming.

        FileStream sourceFile = File.OpenRead(@"C:\Users\Rav\Desktop\rData1.csv");
        FileStream destFile = File.Create(@"C:\Users\Rav\Desktop\Data1.zip");

        GZipStream compStream = new GZipStream(destFile, CompressionMode.Compress,false);

        try
        {
            int theByte = sourceFile.ReadByte();
            while (theByte != -1)
            {
                compStream.WriteByte((byte)theByte);
                theByte = sourceFile.ReadByte();
            }
        }
        finally
        {
            compStream.Dispose();
        }

Use ICSharpCode.SharpZipLib(you can download it) and do the following

       private void CreateZipFile(string l_sFolderToZip)
       {
            FastZip z = new FastZip();
            z.CreateEmptyDirectories = true;
            z.CreateZip(l_sFolderToZip + ".zip", l_sFolderToZip, true, "");

            if (Directory.Exists(l_sFolderToZip))
                Directory.Delete(l_sFolderToZip, true);   

      }



        private void ExtractFromZip(string l_sFolderToExtract)
        {
            string l_sZipPath ="ur folder path" + ".zip";
            string l_sDestPath = "ur location" + l_sFolderToExtract;

            FastZip z = new FastZip();
            z.CreateEmptyDirectories = true;
            z.ExtractZip(l_sZipPath, l_sDestPath, "");

            if (File.Exists(l_sZipPath))
                File.Delete(l_sZipPath);
        }

Hope it helps…
