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; 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) { // Method: HasFiles // 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; } } }
