winform关闭子窗体的同时关闭父窗体

1、父窗体Form1中调用子窗体Form2代码：

Form2 fr = new Form2();
fr.ShowDialog(this);
           

2、子窗体的FormClosed事件代码：

private void Form2_FormClosed(object sender, FormClosedEventArgs e)
        {
            Form1 fr = new Form1();
            fr = (Form1)this.Owner;
            fr.Dispose();
            fr.Close();            
        }
