Hi,

I am using Aspose.Pdf product to open the password protected pdf documents. But my current requirement is to loop the list of passwords until the document open with correct password. please provide me the same code for this.

PdfFileInfopdfFileinfo = null;

try

         {

            pdfFileinfo = new PdfFileInfo(stream);

}

catch (Exception ex)

{

            throw new Exception(string.Format("Unable to open the PDF file.\n<Error>: {0}", ex.Message));

         }

if (pdfFileinfo.IsEncrypted)

{

pdfFileinfo = new PdfFileInfo(stream, "Password-1");                                 

}

Thanks,
