Mergin pdf forms causes a Null Reference Exception

I am working on merging multiple pdf documents and it was failing only when i included a pdf document that had form fields. Here is a very simple code.


FileStream inputStream = new FileStream(".myFile.pdf", FileMode.Open);
MemoryStream outputStream = new MemoryStream();
PdfFileEditor editor = new PdfFileEditor();
editor.Concatenate(new Stream[] { inputStream }, outputStream);
