C#怎样显示隐藏后的窗体

隐藏后的某个窗体怎样在新窗体关闭后显示?
如:
有窗体Form1,Form2
Form1中某事件创建Form2的对象
Form2 frm=new Form2();
frm.Show();
this.Visible=false;

当Form2关闭时怎样把Form1的Visible设置为true?

Answer 1

Form1.cs
private void button1_Click(object sender, EventArgs e)
{
Form2 frm = new Form2();
frm.Show(this);
this.Hide();
}

Form2.cs

private void Form2_FormClosed(object sender, FormClosedEventArgs e)
{
Form frm = this.Owner;
if (frm != null)
{
frm.Show();
}
}
