iText7: Get date of creation of PDF from meta data-CodePudding

I would like to get the date of creation of a PDF using iText7.

I am running into various problems doing so, so I would like to ask for a working solution.

So far, I have not found one.

Thank you.

        Dim pdfDoc As iText.Kernel.Pdf.PdfDocument
        pdfDoc = New iText.Kernel.Pdf.PdfDocument(New iText.Kernel.Pdf.PdfReader(uPath))

        Dim documentinfo As iText.Kernel.Pdf.PdfDocumentInfo = pdfDoc.GetDocumentInfo

        Dim author As String = documentinfo.GetAuthor
        Dim creator As String = documentinfo.GetCreator
        Dim creationDate = documentinfo.GetMoreInfo("CreationDate")
        Dim modificationDate = documentinfo.GetMoreInfo("ModDate")
