        {
            InitializeComponent();
        }
        public string DisplayMessage;
        private void Form2_Load(object sender, EventArgs e)
        {

        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            Text = DisplayMessage;
        }
    }
}

2、子窗体

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form

        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            if(frm!=null)
            frm.Invoke(new MethodInvoker(delegate { frm.DisplayMessage = DateTime.Now.ToString(); }));
        }

        public Form2 frm;
        private void button1_Click(object sender, EventArgs e)
        {
            frm = new Form2();
            frm.Show();
