怎么将很多窗体变成MDI窗体的子窗体
我首先设置了主窗体的ISMDIContainer属性为true，我想启动的时候很多窗体就是它的子窗体
目前用代码for (int k = 0; k < this.MdiChildren.Length; k++)查找子窗体时，发现this.MdiChildren.Length＝0，没有子窗体

具体要怎么写？代码写在哪里？

 //show MDIchild

        public void ShowChild(string childFullName)

        {

            if (!IsExist(childFullName))

            {

                Type type = Type.GetType(childFullName);

                if (type != null)

                {

                    object obj = Activator.CreateInstance(type);

                    Form child = (Form)obj;

                    child.MdiParent = this;

                    child.Dock = DockStyle.Fill;

                    child.Show();

                    childFormList.Add(child);

                }

            }

            else

            {

                Form existForm = childFormList.Find(form => (form.GetType().ToString() == childFullName));

                existForm.Activate();

            }

        }

        // if child has been created

        public bool IsExist(string childFullName)

        {

            foreach (Form f in childFormList)

         &nbs
