csharp 在表单关闭时执行操作

Posted 2021-05-12

frm_to_be_opened form = new frm_to_be_opened();//call your form as you normally do.
form.FormClosing += new FormClosingEventHandler(methodToBeCalled);//add the FormClosing handler
form.Show();//show your form.

//METHOD THAT IS GOING TO BE EXECUTED ON FORM CLOSING EVENT
private void methodToBeCalled(object sender, EventArgs e){
  //your awesome logic here.
}
