Description:-
Here
in this Example I will Explain that How to Extract or Unzip or Convert Files
into the Zip Folder in Asp.Net using C#.Net.
We all know that in Internet If you
want to Download Multiple Files at a time then we must First have to Extract
All Selected File into an Zip Folder then user can Download that Project.
So Implement this Functionality in
our Application we must First have to Download the Ionic.Zip.dll from
DotnetZIP Library.once you Download the File then you have to add the dll File
into the Bin Folder of your project like as shown in Following Image.
Now Add the SampleFiles
folder in your Application for storing the Zip Folder.
Before use this Example you must have to Add the
Following Namespace in your Application like
using
System.IO;
using Ionic.Zip;
Here Ionic.Zip is the dll File that we Include in the Bin
Folder. And Using the Functionality of the Extract Unzip Files to Zip Folder we
must Include this Namespace.
