c# - How to use ListBoxes? -

i'm beginner programming windows applications in c#, not understand basic controls.

lets writing program in select number in listbox, , messagebox displayed number. how associate each item in list event?

thank much. appreciated.

to show message box, have set selectionchanged event:

listbox.selectionchanged += (sender, args) => messagebox.show(listbox.selecteditem.tostring()); 

or simplier beginner:

listbox.selectionchanged += showmessagebox;  private void showmessagebox(object sender, eventargs e) {    messagebox.show(listbox.selecteditem.tostring()); }
