Introduction:
Here
I will explain how to create zip files in asp.net using C#, VB.NET. To create zip
archive files in asp.net using C#, VB.NET we have one library
called DotNetZip library by this we can
easily create zip files.
Description:
In
previous articles I explained Delete
files from uploaded folder in asp.net, create/delete
directory in asp.net,
display
rows as columns in asp.net, Asp.net
Interview questions,
Joins
in SQL Server
and many articles relating to Gridview, SQL ,jQuery,asp.net, C#,VB.NET. Now I will explain how
to create zip files in asp.net using C# and VB.NET.
To
implement this first we need to get Ionic.Zip.dll from DotnetZIP
Library for that check this link Ionic.Zip.dll or you can get it
from attached downloadable code. Now you need to add that dll to your
application bin folder for that
check below steps
Go
to Solution Explorer --> Right click on it and go to Add
ASP.NET folder --> click on Bin
Now
bin folder added to our application and place Ionic.Zip.dll in that folder and
add another folder in your application (Right click on your application -à Select New folder)
and give name as SampleFiles
Once
you added dll and SampleFiles folder
our application will be like this
 |
Now
write the following code to upload files and zip files
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Create ZIP Files in Asp.net using c#,vb.net</title>
</head>
<body>
<form id="form1"
runat="server">
<div>
<asp:FileUpload ID="fileUpload1"
runat="server"
/>
<asp:Button ID="btnUpload"
runat="server"
Text="Upload
Files" onclick="btnUpload_Click" />
<asp:Button ID="btnZip"
Text="Create Zip
Files" runat="server" onclick="btnZip_Click" />
<asp:Label ID="lbltxt"
runat="server"
Font-Bold="true"
ForeColor="Red"
/>
</div>
</form>
</body>
</html>
|
Now in code behind add the following namespaces
C#
Code
using System;
using System.IO;
using Ionic.Zip;
|
Once you add namespaces write the following code in
code behind
// insert files in folder
protected void
btnUpload_Click(object sender, EventArgs e)
{
if(fileUpload1.HasFile)
{
string filename = Path.GetFileName(fileUpload1.PostedFile.FileName);
string path = Server.MapPath("~/SampleFiles/" + filename);
fileUpload1.SaveAs(path);
lbltxt.Text = "File
Uploaded Successfully";
}
}
// Zip all files from folder
protected void
btnZip_Click(object sender, EventArgs e)
{
string path = Server.MapPath("~/SampleFiles/");
string[] filenames = Directory.GetFiles(path);
using (ZipFile
zip = new ZipFile())
{
zip.AddFiles(filenames,"files");
zip.Save(Server.MapPath("~/samplefiles.zip"));
lbltxt.Text = "ZIP
File Created Successfully";
}
}
|
VB.NET
Code
Imports System.IO
Imports Ionic.Zip
Partial Class VBCode
Inherits System.Web.UI.Page
' insert files in folder
Protected Sub
btnUpload_Click(ByVal sender As Object, ByVal e As
EventArgs)
If fileUpload1.HasFile Then
Dim filename As String =
Path.GetFileName(fileUpload1.PostedFile.FileName)
Dim path__1 As String = Server.MapPath("~/SampleFiles/"
& filename)
fileUpload1.SaveAs(path__1)
lbltxt.Text = "File
Uploaded Successfully"
End If
End Sub
' Zip all files from folder
Protected Sub
btnZip_Click(ByVal sender As Object, ByVal e As
EventArgs)
Dim path As String = Server.MapPath("~/SampleFiles/")
Dim filenames As String() = Directory.GetFiles(path)
Using zip As New ZipFile()
zip.AddFiles(filenames, "files")
zip.Save(Server.MapPath("~/samplefiles.zip"))
lbltxt.Text = "ZIP
File Created Successfully"
End Using
End Sub
End Class
