Extract .zip file From folder

Feroz Khan's requirements:

1) Extract a zip

2) Rename the extracted files

The following code or solution I give is merely academic. My hope is that I am providing a foundation for inspiration and ideas for a solution.

Please Note: I didn't have to open any files. If I opened a *.doc I might be a word processor application. If I opened a *.png file I might a graphic applications. All that I really am is just a zip file extractor and file renamer, so I don't need to open any files. I just need to manipulate the files. Also no list box contol. Just a button that runs the process.

This the zip file that going to be extracted: Book.zip

Post Extraction: Inside folder Extraction Point

Files Renamed:

Code to accomplish the task:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

using System.IO.Compression;
namespace SandBox
{
public partial class MyMainForm : Form
{
// Support Variables
OpenFileDialog ofd = null;
public MyMainForm()
{
InitializeComponent();
// Create and Configure OpenFileDialog to our liking
ofd = new OpenFileDialog();
ofd.InitialDirectory = @"C:\"; // when box is opened go here
ofd.Filter = "Zip Files (*.zip)|*.zip|All files (*.*)|*.*"; // option to narrow down files to most perferred
ofd.Multiselect = false; // Limit the user to only select one file
}
private void btnRun_Click(object sender, EventArgs e)
{
// Method: btnRun_Click
// Return: None
// Executes a series steps: File Extraction and File Renaming
// show dialog box
// if the user clicks ok then proceed else abort
if(ofd.ShowDialog() == DialogResult.OK)
{
// user chooses where the zip file is
string fileName = ofd.FileName;
// system extract zip file contents to another location
string newFilePath = Extract(fileName);
// Rename all the files in that extracted location
RenameFiles(newFilePath);
MessageBox.Show("Task completed");
}
}
private void RenameFiles(string filePath)
{
// Method: Raname Files
// Return: None
// Renames files in a specified file-folder location
// NOTE:
// In the real world the user may specify a file naming convention from UI components
// However for this excercise we'll provide a generic file naming convention
// Support Variables
Int16 fileNumber = 0;
string[] files = Directory.GetFiles(filePath);
// if there are extracted files then proceed else abort
if(HasFiles(files)==true)
{
foreach(string file in files)
{
// iterate fileNumber
fileNumber++;
// generate a new file name
string newFileName = String.Concat("Renamed Filed", fileNumber.ToString());
newFileName = string.Concat(filePath, newFileName);
// rename the file
File.Move(file, newFileName);
}
}
}
private string Extract(string fileName)
{
// Method: Extract
// Return: string - the extraction path
// Requirements: Add reference System.IO.Compression.FileSystem
// Extracts a zip to file folder location.
//NOTE:
// In the real world the user may specify the extraction location from UI components
// however for this excercise we'll hardcode the extraction path
// Support Variables
string extractionPath = @"C:\Users\jaxpr\Documents\Extraction Point\";
// Operation
ZipFile.ExtractToDirectory(fileName, extractionPath);
return extractionPath;
}
private Boolean HasFiles(string[] files)
{

// Returns: Boolean
// test a string array for populated elements
// default is false no elements
// returns true if there are elements
Boolean result = false;
// conditions for true
// the string array selectedFiles must be populated
result = (files.Length > 0);
return result;

ZipFile zipFile = new ZipFile("Path TO Your ZIP File");
zipFile.ExtractAll(Application.StartupPath);
