foreach(Form child in this.MdiChildren)
{
child.Close();

private void Form1_Load(object sender, System.EventArgs e)
{
Form2 f=new Form2();
f.MdiParent=this;
f.Show();
Form3 ff=new Form3();
ff.MdiParent=this;
ff.Show();
}
private void button1_Click(object sender, System.EventArgs e)
{
if(this.MdiChildren.Length>0)
{
foreach(Form child in this.MdiChildren)
{
child.Close();
}
}
Form4 f=new Form4();
f.MdiParent=this;
f.Show();

在Form1的函数中：
Form2 f = new Form();
f.ShowDialog();
if(f.flg == true)
{
Application.Run(new Form1());
}
在Form2中定义：
public bool flg = flash;
公有类不：
flg =true;
this.Close();
