MdiChildren有个BUG

 

              private int count = 0;

              private void menuItem3_Click(object sender, System.EventArgs e)

              {

                     Form form = new Form();

                     form.Text = (this.count++).ToString();

                     form.MdiParent = this;

                     form.Closed += new EventHandler(form_Closed);

                     form.Show();

              }

 

              private void Form1_MdiChildActivate(object sender, System.EventArgs e)

              {

                     this.menuItem1.MenuItems.Clear();

                     foreach(Form form in this.MdiChildren)

                     {

                            this.menuItem1.MenuItems.Add(form.Text);

                     }

              }

 

MdiChildren有个BUG，但有窗体关闭后，它的值总还比实际还在打开的窗体个数多一个。最近关闭的窗体没有从MdiChildren中移除，在Form的Closed事件后也没移除，我要在什么时候才能得到实际剩余窗体呀？？？？
