子窗体关闭父窗体

原理为：打开子窗体时，把父窗体的引用传入到子窗体，然后在子窗体中对引用进行操作。

父窗体代码：

private void button1_Click(object sender, RoutedEventArgs e)
{
       Window2 win = new Window2(this);
       win.Owner = this;
       win.ShowDialog();  
}

 

子窗体代码：

        Window1 win; 
        public Window2(Window1 win1)
        {
            InitializeComponent();

            win = win1;
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            this.Close();
            win.Close();
        }
