Hey tnq but I don't want to add other libraries like dotnetzip etc

Solution 3

We still use ICSharpCode.SharpZipLib, it may also be used in commercial closed source applications. Take a look at http://www.icsharpcode.net/opensource/sharpziplib/[^].

Hey tnq but without adding other libraries, I want to zip.

Solution 4

I usually advise three options: SharpCompress, #ziplib and 7-zip for .NET. Please see my past answer: how to add file name in zip folder with same file name in c#[^].

You can use System.IO.Packaging or System.IO.Compression, these have classes that can be used to drop content into a zip file. Its not simple, however.
Here's some blog posts (these explains how to do so)

Hope these would help.

Hey tnq for quick response
It is working, but I want to zip all files of a folder and extraction of file too.

milindaSnow 20-Mar-14 6:04am

I guess You are using DotNetZip library, Its the easiest way.
ex:
using (ZipFile zip = new ZipFile())
{
// add this map file into the "images" directory in the zip archive
zip.AddFile("c:\\images\\personal\\7440-N49th.png", "images");
// add the report into a different directory in the archive
zip.AddFile("c:\\Reports\\2008-Regional-Sales-Report.pdf", "files");
zip.AddFile("ReadMe.txt");
zip.Save("MyZipFile.zip");
}
Use file paths selected from a OpenFileDialog. It should work, and just add them to the archive..
(This sample code was in codeplex)
Hope you got it worked

Hi I used below link which is you sent
http://weblogs.asp.net/jgalloway/archive/2007/10/25/creating-zip-archives-in-net-without-an-external-library-like-sharpziplib.aspx
from dis i got only file which we mention in d code but my problem is I want to zip all files of a particular folder.

Use following where necessary..

OpenFileDialog ofd = new OpenFileDialog();
ofd.Multiselect = true;
ofd.Title = "Select Files to be Archived";

DialogResult dr = ofd.ShowDialog();
try
{
using (ZipFile zip = new ZipFile())
{
foreach (string filePath in ofd.FileNames)
{
try
{
zip.AddFile(filePath);
}
catch (Exception ex)
{
MessageBox.Show("Error" + ex.Message);
}
}
zip.Save("MyZipFile.zip");
}

MessageBox.Show("MyZipFile.zip file created");
}
catch (Exception ex)
{
MessageBox.Show("Archiving Failed");
}

Hope that helped, Let me know of any issues.
regards
