Language
C#
Prerequisite
Visual Studio 2005 and Later
Implementation
1.Right click on project and click on Add References.
2.Add vjslib Reference are in Project Add following namespace
{codecitation class="brush:csharp; gutter: true;" width="650px"} using System.IO;
using java.io;
using java.util.zip; {/codecitation} Step-1
Take one buttons in Aspx Page like,Copy-Past following code in aspx page
{codecitation class="brush: html; gutter: true;" width="650px"} <%@ Page Language="C#" AutoEventWireup="true" CodeFile="CreateZip.aspx.cs" Inherits="CreateZip" %>
DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Untitled Pagetitle>
head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="btnZip" runat="server" Text="Zip Folder"
onclick="btnZip_Click" />
<br />
<br />
<asp:Label ID="lbReport" runat="server">asp:Label>
div>
form>
body>
html> {/codecitation}
Step-2
Copy-past following two method in code file (aspx.cs) of Page
{codecitation class="brush: xml; gutter: true;" width="650px"}
protected void btnZip_Click(object sender, EventArgs e)
{
StringBuilder sb = new StringBuilder();
string ZFileName = String.Format(@"C:\zipfolder\{0}.zip", DateTime.Now.ToString("yyyyMMdd"));
string strDirectory = @"C:\Kirti";
try
{
sb.Append(String.Format("Directory To Zip \n", strDirectory));
sb.Append(String.Format("Zip file: {0}\n", ZFileName));
string[] allFiles = Directory.GetFiles(strDirectory, "*.*", SearchOption.AllDirectories);
if (System.IO.File.Exists(ZFileName))
{
System.IO.File.Delete(ZFileName);
sb.Append(String.Format("Deleted Zip file: \n", ZFileName));
}
FileOutputStream Flostr = new FileOutputStream(ZFileName);
ZipOutputStream Zpoutstr = new ZipOutputStream(Flostr);
Zpoutstr.setLevel(9);
for (int i = 0; i < allFiles.Length; i++)
{
string sourceFile = allFiles[i];
FileInputStream Finstr = new FileInputStream(sourceFile);
ZipEntry ze = new ZipEntry(sourceFile.Replace(strDirectory + @"\", ""));
Zpoutstr.putNextEntry(ze);
sbyte[] buffer = new sbyte[1024];
int len;
while ((len = Finstr.read(buffer)) >= 0)
{
Zpoutstr.write(buffer, 0, len);
}
Finstr.close();
}
Zpoutstr.closeEntry();
Zpoutstr.close();
Flostr.close();
sb.Append(String.Format("Folder {0} Zipped successfuly to File {1}.", strDirectory, ZFileName));
}
catch (Exception eX)
{
sb.Append(String.Format("Error zipping folder {0}. Details: {1}. Stack Trace: {2}.", strDirectory, eX.Message, eX.StackTrace));
}
lbReport.Text = sb.ToString();
}
{/codecitation}
Conclusion
We can easily make zip file using .net.
Enjoy!!!!!! Happy Coding.
