Answer 2

Source code taken from MSDN that is compatible to .Net 2.0 and above

public static void CompressFile(string path)
        {
            FileStream sourceFile = File.OpenRead(path);
            FileStream destinationFile = File.Create(path + ".gz");

            byte[] buffer = new byte[sourceFile.Length];
        sourceFile.Read(buffer, 0, buffer.Length);

        using (GZipStream output = new GZipStream(destinationFile,
            CompressionMode.Compress))
        {
            Console.WriteLine("Compressing {0} to {1}.", sourceFile.Name,
                destinationFile.Name, false);

            output.Write(buffer, 0, buffer.Length);
        }

        // Close the files.
        sourceFile.Close();
        destinationFile.Close();
    }

I'm adding this answer as I've found an easier way than any of the existing answers:

1. Install DotNetZip DLLs in your solution (easiest way is to install the package from nuget)
2. Add a reference to the DLL.
3. Import the namespace by adding: using Ionic.Zip;
4. Zip your file

Code:

using (ZipFile zip = new ZipFile())
{
    zip.AddFile("C:\test\test.txt");
    zip.AddFile("C:\test\test2.txt");
    zip.Save("C:\output.zip");
}

If you don't want the original folder structure mirrored in the zip file, then look at the overrides for AddFile() and AddFolder() etc.

Answer 4

Use http://dotnetzip.codeplex.com/ to ZIP files or directory, there is no builtin class to do it directly in .NET

Answer 5

There is a built-in class in System.IO.Packaging called the ZipPackage:

You can just use ms-dos command line program compact.exe. Look on a parameters compact.exe in cmd and start this process using .NET method Process.Start().
