c# winform 窗体 对话框绑定的值如何填到主窗体问题

这段代码放在主窗体中

private void txt_KeJiaAModel_DoubleClick(object sender, EventArgs e)
        {TimerEvent();
}

/// 

        /// 将此函数放到要开始计时的函数事件下
        /// 

        private void TimerEvent()
        {
            System.Timers.Timer t = new System.Timers.Timer(1 * 0.5 * 0.5 * 1000);
            t.Elapsed += new System.Timers.ElapsedEventHandler(timeup);
            t.Enabled = true;
        }
        private void timeup(object sender, System.Timers.ElapsedEventArgs e)
        {
            //调用点击事件
           this.事件名.PerformClick();
            //点击事件调用结束后停止计时
            t.Stop();
        }
        private void 事件名()
        {
            //赋值
            this.文本控件Name.Text = "窗体过来的值 ";
        }
