This code demonstrates how to replace text in a PDF file using the IronPDF library in C#. First, ensure you have the IronPDF library installed via NuGet. The code loads an existing PDF through the FromFile method, replaces text on the specified page using ReplaceTextOnPage, and saves the result as a new PDF file. The page number, text to replace, and new text need to be specified. Finally, the changes are saved with SaveAs, and a message is printed to confirm the operation is complete.
