Hi,
I am using free version of Spire.PDF for my project. Here is my code.
PdfDocument doc = new PdfDocument();
doc.LoadFromFile(Path.GetFullPath(pdfFilePath),FileFormat.PDF);
But I am getting error: An unhandled exception of type 'System.ArgumentNullException' occurred in Spire.Pdf.dll
Additional information: Value cannot be null.
I have attached my PDF for sample.
Thank you in advance.
