c# - How do I copy the whole content of a pdf? -

helllo,

i want transfer pdf c# program using .net 3.5. know, there libs that, not allowed use such. came idea copy content of pdf file manually , transform datatable. because want work automatically using code:

process adope = new process(); adope.startinfo.filename = fd.filename.tostring(); adope.startinfo.arguments = fd.filename.tostring(); adope.start(); intptr adobe_handler = intptr.zero;   while (elapsed_time.elapsedmilliseconds <= 5000) {     adobe_handler = findwindow("acrobatsdiwindow", fd.safefilename + " - adobe reader");         if (adobe_handler != intptr.zero) {             break;          }         system.threading.thread.sleep(200); } if (adobe_handler == intptr.zero) {     messagebox.show("adobe not running");     return; }  elapsed_time.stop();  clipboard.clear();  setforegroundwindow(adobe_handler); elapsed_time.start(); while (pdf_info.equals("")&&elapsed_time.elapsedmilliseconds<=10000) {     clipboard.clear();     sendkeys.sendwait("^a");     sendkeys.sendwait("^c");     pdf_info = clipboard.gettext().tostring(); } elapsed_time.stop(); adope.close(); 

it works... sometimes. looking better way or improvement. idea?
