How can we set Expiry date to Pdf in c#

[abhiseky93]

// Create a PDF Document
ceTe.DynamicPDF.Merger.PdfDocument pdf = new ceTe.DynamicPDF.Merger.PdfDocument("Abhishek.pdf");
MergeDocument document = new MergeDocument(pdf);
//add the java script to the string
string expiryDate = "var LastDay = 07; var LastMonth = 07; var LastYear = 2017; " +
" var today = new Date(); " +
" var myDate=new Date(); " +
" LastMonth = LastMonth - 1; " +
" myDate.setFullYear(LastYear,LastMonth,LastDay); " +
" if (myDate<today) " +
" {app.alert(\"This file is expired\"); this.closeDoc(1);} ";
document.JavaScripts.Add(new DocumentJavaScript("js", expiryDate));
document.Draw("Output.pdf");

This code does not work

Dear abhiseky93,

Thanks for your inquiry.
From your code, I thought you were not using our Spire.PDF. I am afraid we are unable to help you.
Below is the code provided by Spire.PDF to set the expiry date.

Code: Select all

            //create a document
            PdfDocument document = new PdfDocument();
            //add a page
            PdfPageBase pageone = document.Pages.Add();
            //add the java script to the string
            string expiryDate = "var LastDay = 07; var LastMonth = 07; var LastYear = 2017; " +
            " var today = new Date(); " +
            " var myDate=new Date(); " +
            " LastMonth = LastMonth - 1; " +
            " myDate.setFullYear(LastYear,LastMonth,LastDay); " +
            " if (myDate<today) " +
            " {app.alert(\"This file is expired\"); this.closeDoc(1);} ";
            PdfJavaScriptAction action = new PdfJavaScriptAction(expiryDate);
            document.AfterOpenAction = action;           
            document.SaveToFile("14337.pdf");
            System.Diagnostics.Process.Start("14337.pdf");
