View Archive Entries

Viewing archive entries in this code example means examining or inspecting the contents of a file within the ZIP archive without extracting it. IronZIP allows users to browse the contents of the archive and preview the files' names without fully extracting them.

To view the archive entries, first, open the archive by passing the archive file path to the constructor. From there, use the GetArchiveEntryNames method. This method will return a list of entries inside the currently opened archive.

        if (args.Length == 0)

            Console.WriteLine("Please provide the path to the zip archive.");

Explanation:

• We assume the existence of a fictional library called IronZip for handling ZIP files.
• The Main method checks if a file path is provided via command-line arguments.
• The ZipArchive class (hypothetical) is used to open the specified archive file.
• The GetArchiveEntryNames() method is called to get a list of names of the files within the ZIP archive.
• We use a try-catch block to handle any potential exceptions and ensure that proper error messages are displayed to the user.
• Finally, we iterate over the list of entry names and print each entry to the console. This allows the user to see the contents of the archive without extracting the files.
