Compress a file saved in Database

From . NET Framework 4.5 Beta, it is possible to manipulate ZIP files. Example based in this:

using System;
using System.IO;
using System.IO.Compression;
using System.IO.Compression.FileSystem;

namespace ConsoleApplication
{
    class Program
    {
        static void Main(string[] args)
        {
            using (FileStream zipToOpen = new FileStream(@"c:\users\exampleuser\Desktop\release.zip", FileMode.Create))
            {
                using (ZipArchive archive = new ZipArchive(zipToOpen, ZipArchiveMode.Create))
                {
                    archive.CreateEntryFromFile(@"c:\users\exampleuser\Desktop\MeuArquivoACompactar.dat", "arquivo.dat");
                }
            }
        }
    }
}
