how to Read text of PDF file in asp.net

Chris D · Answer

You could try PDFDocument class (ParsePages method) from Leadtools. I am currently using this method to extract different objects from PDF documents (including Text data). You can find more details on their own website https://www.leadtools.com/sdk/pdf.

// create an instance of the pdfparser class PDFParser pdfParser = new PDFParser(); // extract the text String result = pdfParser.ExtractText(pdfFile); OR form1.Controls.Clear(); form1.Controls.Add(grdv1); StringWriter sw = new StringWriter(); HtmlTextWriter htw = new HtmlTextWriter(sw); grdv1.RenderControl(htw); string html = " " + sw.ToString() + " "; Response.Clear(); Response.ContentType = "application/pdf"; Response.AddHeader("content-disposition", "attachment;filename=Export.pdf"); Document document = new Document(PageSize.A4, 80, 50, 30, 65); PdfWriter writer = PdfWriter.GetInstance(document, Response.OutputStream); document.AddAuthor("Hua Min"); document.AddSubject("Export To pdf"); document.Open(); string tempFile = Path.GetTempFileName(); using (StreamWriter tempwriter = new StreamWriter(tempFile, false)) { tempwriter.Write(html); } HtmlParser.Parse(document, tempFile); document.Close(); writer.Close(); File.Delete(tempFile); writer = null; document = null; Response.End();
