VB.Net code to check if password is pdf protected

Hi Team,

I am new to VB.Net can you please help with the sample code to check if the pdf file is password protected. If it is password protected move the file to the backup folder.

Thanks in Advance

Regards,

Install Spire.PDF via NuGet. You'll be able to determine if a PDF document is password protected using the following sample code.

Imports Spire.Pdf
Imports System
Namespace ProtectedOrNot
Class Program
Private Shared Sub Main(ByVal args() As String)
Dim fileName As String = "Sample.pdf"
Dim value As Boolean = PdfDocument.IsPasswordProtected(fileName)
Console.WriteLine(value)
Console.ReadKey
End Sub
End Class
End Namespace
