Mutiple files compression into a single Archive file

[Mohan]

Hi,

I would like to compress multiple files in to a single Archive file.

The Archive file should be in the standard format so that I can open the
same using the standard Zip tools like WinZip etc..

Please suggest me on this how to go ahead..



Thanks & Regards,
Mohan

..NET out of the box only supports single file compression (GZIP).

Get an extra library like SharpZipLib for creating zip files.

I can find some examples for that library if needed.

Peter Duniho explained on 9/28/2010 :

Find a third-party library that will handle the .zip format? Alternatively,
execute pkzip.exe or something similar as an external process to do the work.

AFAIK, .NET has no support for the .zip container format.

Actually, it does... Via the System.IO.Packaging namespace...

using System;
using System.IO;
using System.IO.Packaging;

namespace ConsoleApplication85
{
class Program
{
static void Main ( string[] args )
{
string path = Path.Combine (
Environment.GetFolderPath ( Environment.SpecialFolder.MyDocuments ),
"Beehive Plans" );

using ( Package pkg = ZipPackage.Open ( "beehive.zip", FileMode.Create ) )
{
foreach ( string file in Directory.GetFiles ( path ) )
{
PackagePart part = pkg.CreatePart (
new Uri ( "/" + Path.GetFileName(file), UriKind.Relative ),
System.Net.Mime.MediaTypeNames.Application.Octet,
CompressionOption.Maximum );
byte[] content = File.ReadAllBytes ( file );
part.GetStream ().Write ( content, 0, content.Length );
}
}
}
}
}

But, in can be a bit tricky about mime types - I tend to use sharpziplib
instead
