Where does ZipSaveOptions live in the IronZip API?

ZipSaveOptions is a class in the IronZip namespace, shipped in IronZip.dll. Construct it with new ZipSaveOptions(), then pass it to IronZipArchive.Save or SaveAs, or assign it to the archive's ZipSaveOptions property.

How do you set a ZIP password in C# with ZipSaveOptions?

Set the Password property and choose an EncryptionMethod (AES256, AES128, or Traditional), then pass the options to SaveAs or Save. Leaving Password unset writes an unencrypted archive.

Class ZipSaveOptions

Provides options for configuring an IronZip archive.

Inheritance

System.Object

ZipSaveOptions

Namespace: IronZip

Assembly: IronZip.dll

Syntax

public class ZipSaveOptions : Object

The compression level, password, and encryption method for a save are carried by ZipSaveOptions. It groups the three settings that control how an archive is written so they travel together instead of as loose arguments. Construct one with new ZipSaveOptions() and set the properties that matter.

Compression sets the level for the size-versus-speed trade-off, Password sets the password applied to the archive, and EncryptionMethod selects the scheme through an EncryptionMethods value (AES256, AES128, or Traditional). Pass the configured object to IronZipArchive.SaveAs(path, options) or Save(options), or assign it to the archive's ZipSaveOptions property so later saves reuse it. Leaving Password unset writes an unencrypted archive. Reusing one options object across saves keeps a consistent password and compression for a batch of archives, and the object read back from the ZipSaveOptions property shows what a loaded archive will apply on its next save.

using IronZip;

using var archive = new IronZipArchive();
archive.Add("report.pdf");
archive.SaveAs("secure.zip", new ZipSaveOptions { Password = "p@ss", EncryptionMethod = EncryptionMethods.AES256 });

The password-protect ZIP example uses these options, and the create ZIP example shows a plain save for comparison.
