Create Zip Files Archive In Asp.Net C# VB

This example explains how to Create Zip Files In Asp.Net Using C# And VB.Net. Several times while developing Asp.Net applications we need to upload files to server and Create Zip File or Archive from those uploaded files.

We can easily Create Zip Files Archives using DotNetZip

Create a Bin Folder in solution explorer and put Ionic.Zip.dll in it.

Place one FileUpload control on aspx page and one button to upload files and create zip file in it's Click Event.

We can Delete Files From Server Or Directory After creating Zip File by writing code after calling Save() method of zipfile object,and Display Files In GridView From Server.
