窗体2 和窗体3 都是动态创建出来的

现在 FORM3.TEXT要即时 = FORM2.TEXT

FORM1窗体代码

        Form2 f2 = new Form2();
        Form3 f3 = new Form3();
        private void Form1_Load(object sender, EventArgs e)
        {
            f2.XYZ += new Form2.CallBack(GetForm2TextBox1Text);

            f2.Dock = DockStyle.Fill;
            f2.TopLevel = false;
            f2.FormBorderStyle = FormBorderStyle.FixedToolWindow;
            f2.Parent = panel1;
            f2.Show();

            f3.Dock = DockStyle.Fill;
            f3.TopLevel = false;
            f3.FormBorderStyle = FormBorderStyle.FixedToolWindow;
            panel2.Controls.Add(f3);
            f3.Show();         
        }

        private void GetForm2TextBox1Text(string s)
        {
            f3.textBox1.Text = s;
        }

FORM2窗体代码

        public delegate void CallBack(string s);
        public event CallBack XYZ;

        private void textBox1_TextChanged(object sender, EventArgs e)
        {
            XYZ(textBox1.Text);
        }
