c# - Refresh a listbox to display new values -

this newb question i'm sorry.

i'm filling out text box values im grabbing on line , passing them listbox so:

        // textbox1.text = test.tostring();         string[] names = result.split('|');         foreach (string name in names)         {              listbox1.items.add(name);         } 

however i'm trying click on folder , have files displayed there shown in listbox1. i've tried:

   using (var testy = new webclient())         {              test = testy.downloadstring("http://server.foo.com/images/getdirectorylist.php?dir=test_folder");             string[] names1 = test.split('|');             foreach (string name in names1)             {                 listbox1.items.clear();                 listbox1.items.add(name);                 listbox1.update();             }          } 

but happens listbox empties , doesn't refreshed. how can achieve want do?

your lines

        foreach (string name in names1)         {             listbox1.items.clear();             listbox1.items.add(name);             listbox1.update();         } 

makes every string removing ever other item in list.

i'm pretty sure that's not want
