Trailer object is null.: v3.7.0.0

Hi,

I am getting the following error “Trailer object is null.: v3.7.0.0”. I am using the latest version of pdf kit with .NET 3.5. Any help is appreciated

at Aspose.Pdf.Kit.PdfFileEditor.Concatenate(Stream[] inputStreams, Stream outputStream)
at ConsoleApplication1.Program.Main(String[] args)


fsInputStream[0] = File.Open(@“C:\temp\100009642.pdf”, FileMode.Open, FileAccess.Read, FileShare.Read);
fsInputStream[1] = File.Open(@“C:\temp\100009643.pdf”, FileMode.Open, FileAccess.Read, FileShare.Read);

fsOutputStream = File.Open(@“c:\temp\big.pdf”, FileMode.OpenOrCreate, FileAccess.ReadWrite);
pdfFileEditor.Concatenate(fsInputStream, fsOutputStream);

I have also tried the following:

files[0] = @“C:\temp\100009642.pdf”;
files[1] = @“C:\temp\100009643.pdf”;
pdfFileEditor.Concatenate(files, @“c:\temp\big1.pdf”);

The above code does not throw an exception, it created the file with zero bytes.

Thanks,
Nagendra
