Using NuGet Package Manager

1. Right-click on your project in Solution Explorer.
2. Select "Manage NuGet Packages..."
3. Search for "IronZip" and click "Install."

Using Package Manager Console

1. Open the Package Manager Console.

2. Run the following command:

   Install-Package IronZip

Importing Required Libraries

using IronZip;
using IronZip.Enum;

using IronZip;
using IronZip.Enum;

Imports IronZip
Imports IronZip.Enum

These lines import the necessary namespaces from the IronZIP library: IronZip contains the main classes and functionality, while IronZip.Enum includes enums used in the library.

Main Program Class

class Program
{
    static void Main()
    {
        // Code execution starts here
    }
}

class Program
{
    static void Main()
    {
        // Code execution starts here
    }
}

Friend Class Program
	Shared Sub Main()
		' Code execution starts here
	End Sub
End Class

This is the main class of the program with the Main method where the code execution begins.

Creating an Empty ZIP Archive

using (var archive = new IronZipArchive(9)) 
{ 
     // Code within the 'using' block 
}

using (var archive = new IronZipArchive(9)) 
{ 
     // Code within the 'using' block 
}

Using archive = New IronZipArchive(9)
	 ' Code within the 'using' block 
End Using

The using statement ensures that the IronZipArchive object is disposed of properly after its use. It creates a new instance of IronZipArchive with the highest compression level (9).

Password Protecting the ZIP Archive

The following single line of code adds password protection to the ZIP archive:

archive.Encrypt("P@ssw0rd", EncryptionMethods.Traditional);

archive.Encrypt("P@ssw0rd", EncryptionMethods.Traditional);

IRON VB CONVERTER ERROR developers@ironsoftware.com

The Encrypt method is called on the archive object to password-protect the ZIP file. It takes two parameters: the password string ("P@ssw0rd") and the encryption method (EncryptionMethods.Traditional).

IronZIP also provides AES128 and AES256 advanced password protection which is more secure and prevents manipulation of ZIP files.

Adding Files to the ZIP Archive

archive.Add("./assets/file1.txt");
archive.Add("./assets/image1.png");

archive.Add("./assets/file1.txt");
archive.Add("./assets/image1.png");

archive.Add("./assets/file1.txt")
archive.Add("./assets/image1.png")

The Add method is used to add files to the ZIP archive. In this example, one text file and one image file (file1.txt and image1.png) located in the "./assets/" directory are added to the archive.

These are the files to be added:

Exporting the ZIP Archive

archive.SaveAs("output.zip");

archive.SaveAs("output.zip");

archive.SaveAs("output.zip")

The SaveAs method is called to export the ZIP archive. It specifies the output filename as "output.zip". This creates the password-protected ZIP file with the specified content and password.

Here's the complete source code with separated string paths and a password property for better control:

using IronZip;
using IronZip.Enum;

class Program
{
    static void Main()
    {
        // Define password and file paths for the ZIP archive
        string password = "P@ssw0rd";
        string filename = "./assets/file1.txt";
        string imagename = "./assets/image1.png";

        // Create a new ZIPArchive with the highest compression level
        using (var archive = new IronZipArchive(9))
        {
            // Add Password to protect the ZIP (Support AES128 & AES256)
            archive.Encrypt(password, EncryptionMethods.Traditional);

            // Add files to the archive
            archive.Add(filename);
            archive.Add(imagename);

            // Export the Encrypted ZIP file archive
            archive.SaveAs("output.zip");
        }
    }
}

using IronZip;
using IronZip.Enum;

class Program
{
    static void Main()
    {
        // Define password and file paths for the ZIP archive
        string password = "P@ssw0rd";
        string filename = "./assets/file1.txt";
        string imagename = "./assets/image1.png";

        // Create a new ZIPArchive with the highest compression level
        using (var archive = new IronZipArchive(9))
        {
            // Add Password to protect the ZIP (Support AES128 & AES256)
            archive.Encrypt(password, EncryptionMethods.Traditional);

            // Add files to the archive
            archive.Add(filename);
            archive.Add(imagename);

            // Export the Encrypted ZIP file archive
            archive.SaveAs("output.zip");
        }
    }
}
