Read info of pdf file without reading whole file

Question

I need to get the information of pdf file.

There is my code:

PdfReader reader = new PdfReader(fileName);
var info = reader.Info;

I don't need to read the whole file: if there are a lot of pdf files, this operation may take a lot of time..

How can I get info without reading whole file?

Answer 1

That's explained in Chapter 6 of the official documentation:

PdfReader reader = new PdfReader(new RandomAccessFileOrArray(file), null);
