• Answer:

  You can use http://bitmiracle.com/pdf-library/ for this (I work for Bit Miracle). Docotic.Pdf comes with commercial and free licenses. Here is a sample for how to search text in PDF: PdfDocument doc = new PdfDocument("file.pdf"); string textToSearch = "some text"; for (int i = 0; i < doc.Pages.Count; i++) { string pageText = doc.Pages[i].GetText(); int count = 0; int lastStartIndex = pageText.IndexOf(textToSearch, 0, StringComparison.CurrentCultureIgnoreCase); while (lastStartIndex != -1) { count++; lastStartIndex = pageText.IndexOf(textToSearch, lastStartIndex + 1, StringComparison.CurrentCultureIgnoreCase); } if (count != 0) Console.WriteLine("Page {0}: '{1}' found {2} times", i, textToSearch, count); } You may want to remove third argument for IndexOf method if you want to perform case-sensitive search.
