I am reading the text of pdf invoices to extract different informations (eg. customer, id, amount etc.) and am currently trying out different variants.

Hi,

Thanks for your inquiry.
Yes, you can use PdfTextExtractOptions.IsExtractAllText method to extract all text of Pdf file, then handle the text to get the desired content. I put the complete code below for your reference.

Code: Select all

String input = @"..\..\..\..\..\..\Data\PDFTemplate-Az.pdf";
            PdfDocument doc = new PdfDocument();
            // Read a pdf file
            doc.LoadFromFile(input);

            // Get the first page
            PdfPageBase page = doc.Pages[0];

            // Extract text from page keeping white space
            PdfTextExtractOptions options = new PdfTextExtractOptions();
            options.IsExtractAllText = true; //false->Extract text from page without keeping white space
            PdfTextExtractor pdfTextExtractor = new PdfTextExtractor(page);
            String text = pdfTextExtractor.ExtractText(options);

            String result = Path.GetFullPath("ExtractTextFromParticularPage_out.txt");
            // Create a writer to put the extracted text
            TextWriter tw = new StreamWriter(result);

            // Write a line of text to the file
            tw.WriteLine(text);
