Getting Started: Creating a ZIP Archive

Below is a simple example demonstrating how to create a ZIP archive using Aspose.ZIP for .NET. This example showcases adding multiple files to a ZIP file programmatically.

using Aspose.Zip;
using Aspose.Zip.Compression;

namespace ZipExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Initialize the archive
            using (Archive archive = ArchiveFactory.Create(ArchiveType.Zip))
            {
                // Add files to the archive
                archive.AddEntry("Documents/Resume.pdf", @"C:\Files\Resume.pdf");
                archive.AddEntry("Images/Photo.jpg", @"C:\Files\Photo.jpg");
                archive.AddEntry("Reports/AnnualReport.xlsx", @"C:\Files\AnnualReport.xlsx");

                // Save the archive to disk
                archive.Save("C:\\Archives\\MyArchive.zip");
            }

            System.Console.WriteLine("ZIP archive created successfully.");
        }
    }
}

Explanation

  1. Initialize the Archive: An instance of the Archive class is created, specifying the ZIP format.
  2. Add Entries: Files are added to the archive using the AddEntry method, where you specify the path within the ZIP and the file system path.
  3. Save the Archive: The Save method writes the ZIP file to the specified location on disk.
  4. Completion Message: A confirmation message is displayed upon successful creation of the ZIP archive.

Conclusion

Aspose.ZIP for .NET is a versatile and powerful library that simplifies ZIP file operations for developers. With its extensive feature set, performance optimizations, and ease of integration, it stands out as an essential tool for any .NET developer working with archive files. Whether you’re compressing data, securing sensitive information, or managing large-scale archives, Aspose.ZIP provides the capabilities needed to implement these functionalities efficiently and effectively.
