如何从子窗口关闭程序主窗体窗口(WPF)

WindowMain中

private void button_Click(object sender,EventArgs e)

{

WindowSon son = new WindowSon();

son.Owner = this;

this.Hide();

son.ShowDialog();

}

WindowSon中关闭主窗体(整个应用程序)

private void btn_Exits_Click(object sender, RoutedEventArgs e)
{
WindowMain wm = (WindowMain)this.Owner;
this.Close();
wm.Close();

}

小弟初学C#及WPF,还望各位多多指教!
