How to Add and Remove Attachments in PDF C#

In this tutorial, we delve into adding and removing file attachments in PDF documents using IronPDF within a .NET application. Start by ensuring the IronPDF NuGet package is installed in your project, which can be done swiftly via the NuGet package manager. After installing, import the IronPDF namespace in your Program.cs file and set the license key to unlock full functionality.

To add an attachment, open an existing PDF file using the PdfDocument.FromFile method. Load the desired file into a byte array and use the PdfDocument.Attachments.AddAttachment method to attach it. Save the updated PDF using the SaveAs method. For removing attachments, load the saved PDF, retrieve the attachment list, and use the RemoveAttachment method. Post-removal, save the changes. Running the application will confirm the successful addition and removal of attachments. This method enhances PDF documents by embedding additional files.
