In this article
I am going to explain how we can make a zip of files and how we can make
unzip(extract) files in asp.net. To achieve this we need to add Ionic.Zip.dll
reference from DotnetZIP Library.
Now let me explain the working of my application..
Below image shows my add Ionic.Zip.dll reference.
1. MyUploadedFile -> We will make zip of all files of this folder and save
on root.
2. MyExtractFile -> We will save all extracted file from a zip file.
Image 1.
Below is my Application working.. On Click of Create Zip Files I am making a zip
file. And on Click of Extract Zip Files,
I am extracting all zip files.
Image 2.
You can see zip file created...
Image 3.
On Click of Extract
Zip Files you can see all extracted files inside MyExtractFiles folder...

Now My aspx code is:
<%@ Page Language="C#"
AutoEventWireup="true"
CodeFile="Default.aspx.cs"
Inherits="_Default"
