Read data from searchable pdf

Question

Hello, I have a searchable pdf. I want to read certain data from it e.g. (Name: Verona, City: Amsterdam).
How can I do it in C# without having to use an expensive library?
Thanks for the help!

If you want to extract text from PDF, you can use itext7

A basic sample :

            PdfReader pdfReader = new PdfReader("e:\\test.pdf");
            PdfDocument pdfDoc = new PdfDocument(pdfReader);
            for (int nPage = 1; nPage <= pdfDoc.GetNumberOfPages(); nPage++)
            {
                iText.Kernel.Pdf.Canvas.Parser.Listener.ITextExtractionStrategy extractionStrategy = new iText.Kernel.Pdf.Canvas.Parser.Listener.SimpleTextExtractionStrategy();
                string sPageText = iText.Kernel.Pdf.Canvas.Parser.PdfTextExtractor.GetTextFromPage(pdfDoc.GetPage(nPage), extractionStrategy);
                Console.WriteLine(string.Format("Page : {0}", nPage.ToString()));
                Console.WriteLine(sPageText);
            }
            pdfDoc.Close();
            pdfReader.Close();
