Sometimes we need to do some processing of PDF files, extracting text, merging, and so on. Before we used the A-pdf Text extractor free tool, why not write one yourself??  now we can use PDFBox-0.7.3 this open source class library. After downloading the package reference:   Code as follows: Pdfbox-0.7.3.dll IKVM. Gnu. Classpath.dll     Create a new project, the code is simple: The code is as follows: public static string Parsetotxtstringusingpdfbox (string filename) { PDDocument doc = pddocument.load (filename); Pdftextstripper stripper = new Pdftextstripper (); Return Stripper.gettext (DOC);     Get this textstring, and then write them into a disk file, like this:   code as follows: public static void Writetotextfile (String str,string t Xtpath) {if (string). IsNullOrEmpty (Txtpath)) throw new ArgumentNullException ("Output file path should not is Null"); using (var txtwriter = new StreamWriter (Txtpath)) {txtwriter.write (str); Txtwriter.close ();}}     Other functions you can play by yourself. This class library currently supports:   PDF to text extraction Merge PDF Documents pdf Document encryption/decryption Lucene Search Engine Integr ation Fill in form data FDF and XFDF create a PDF from a-text file Create images from PDF pages Print a PDF
