VB.Net Merge multiple pdfs into one and export

Question

I have to merge multiple PDFs into a single PDF.

I am using the iText.sharp library, and collect converted the code and tried to use it (from here) The actual code

Answer 1

Some may have to make a change to the code at "writer = PdfWriter.GetInstance(pdfDoc, New FileStream(outputPath, FileMode.OpenOrCreate))" as iTextSharp may not support

Change to:

Dim fs As IO.FileStream = New IO.FileStream(outputPath, IO.FileMode.Create)

writer = iTextSharp.text.pdf.PdfWriter.GetInstance(pdfDoc, fs)
