Winform form closed event
提问by Saif Khan
I have 2 forms, Main and Child. When a button is clicked on the Main form, the Child form is loaded. Can I catch from the Main form, when the Child form is closed by subscribing to the closed event of the child form?
我有 2 个表格，Main 和 Child。单击主窗体上的按钮时，会加载子窗体。当通过订阅子窗体的关闭事件关闭子窗体时，我可以从主窗体捕获吗？

Yes you can, it's pretty straightforward:
是的，你可以，这很简单：
private void LoadChildForm_Click(object sender, EventArgs e)
{
ChildForm form = new ChildForm();
form.FormClosed += new FormClosedEventHandler(ChildFormClosed);
form.Show();
}
void ChildFormClosed(object sender, FormClosedEventArgs e)
{
// do something useful
}
