c# - Hidden form not closing -

i have c# form, have form1 shown @ start, , when press go taken form2. form1 hidden , form2 shown.

now when exit form2, whole application should closed. using application.exit() when press exit button. facing problems if user presses x or alt+f4 or rightclick->close. form close hidden form stay opened.

how can fix that? when press 1 of these control button, hidden forms close?

i tried form1_close , form1_closing function didn't seem work.

try this:

hide(); form2 form2 = new form2(); form2.closed += (s, args) => this.close(); form2.show(); 

this close form1 when close form2. if user presses x or alt+f4 or rightclick -> close on form2 form2 , hidden form1 close.
