PdfExtractor leaves the source file open

Aspose.PDF Product Family

Hi,

when calling PdfExtractor.Bind with string parameter containing filename, PdfExtractor opens a filestream, and this stream is still open after the extraction is done. So afterward this file is inaccessible until the PdfExtractor instance is garbagecollected.
You should probably derive PdfExtractor from IDisposible and provide a Close method.

Cheers

i run Aspose.Pdf.Kit 2.0.0.0 on an W3K Server and .NET 2.0. I use FileMon from Sysinternals to monitor the file. What i see is an OPEN, READ, READ EOF, but there is no CLOSE.

try this:

string path = @“C:\Temp\Test.pdf”;
string text;
PdfExtractor extractor = new PdfExtractor();
extractor.BindPdf(path);
extractor.ExtractText();
using (MemoryStream ms = new MemoryStream())
{
extractor.GetText(ms);
text = Encoding.UTF8.GetString(ms.GetBuffer());
ms.Close();
}
File.Delete(path);


You get an exception on the last line. Something like this:
System.IO.IOException: The process cannot access the file ‘C:\Temp\Test.pdf’ because it is being used by another process.

Hi Shahzad,

I was using 3.3.0.0. I downloaded the latest and found a new Close() method. This fixes my problem.

Thanks
