Error in encrypted file: Source array was not long enough. Check srcIndex and length- and the array's lower bounds

Hi

I have one encrypted stream, and I try to find out if it is encrypted or not by foillowing code:

PdfFileInfo inputPDFInfo = new PdfFileInfo(pdfInputStream);

if (inputPDFInfo.BeEncrypted)

{

MessageBox.Show("Encrypted file"

}

Now when I initialize this object "PdfFileInfo" it throws following error:

"Source array was not long enough. Check srcIndex and length, and the array's lower bounds"

Please help me,

If file is not encrypted it is not throwing error

Regards
