private void btnCreate_Click (object sender, EventArgs e)
        {

            for (int i = 1; i <3; i ++)
            {
                _i = i;
                MethodInvoker mi = new MethodInvoker (this.InvokeFun);
                BeginInvoke (mi);
                
            }
        }

        private void InvokeFun ()
        {
            MdiChild formMdiChild = new MdiChild ();
            formMdiChild.LineNo = _i;
            formMdiChild.Text = _i.ToString ();
            formMdiChild.MdiParent = this;

            Thread t = new Thread (new ThreadStart (formMdiChild.Show));
            t.Start ();
        }

You set up MDI through delegation, not through threads.

Thread establishment should be Thread thread = new Thread (new ThreadStart (creat_MDIChild));

       public void creat_MDIChild ()
           {
                MethodInvoker mi = new MethodInvoker (this.InvokeFun);
                this.BeginInvoke (mi);
                
            }

        private void InvokeFun ()
        {
            MdiChild formMdiChild = new MdiChild ();
            formMdiChild.LineNo = _i;
            formMdiChild.Text = _i.ToString ();
            formMdiChild.MdiParent = this;
        }
