Serial port Communication problem

hello , using visual c# develop program read information send via serial port arduino uno board , uploaded program send number 0 1023 delaying 1 second ( depending on input signal ) , program has read signal , display in listbox . have declared infinite loop ( ) , permanently reads input value .

my written code working , when press button , includes code below , program hanging ( doesn't functioning more ) , values in listbox being added , can't press other buttons , can't close program .

code looks :

string input = "";  arduinoport.open ();  (int = 0;;i++)  {     info = arduinoport.readline();     listbox1.items.add (info);  }  arduinoport.close();		

hi,

to avoid hanging use application.doevents()

eg:

string input = "";
arduinoport.open ();
for (int = 0;;i++)
{
   info = arduinoport.readline();
   listbox1.items.add (info);

  application.doevents();
}
arduinoport.close();
