c# - 显示 'saved' 标签 2 秒然后在 c# asp.net 中隐藏

Question

在将数据保存为仅可见(visible = true)后显示 label(包含文本 = 已成功保存)然后在说 2 后消失(变为可见 = false)的最佳方式是什么秒？我以前见过有人使用定时器，但无法让它们工作。

if (saved == true)
{
   //data saved - show label and then make visible = false
   lblsuccess.Visible = true;
   lblsuccess.Text = "Visit saved";
}

System.Timers.Timer timer1;


timer1 = new System.Timers.Timer(2000);
timer1.Enabled=false;
timer1.Elapsed += new ElapsedEventHandler(timer1_Elapsed);
void timer1_Elapsed(object sender, ElapsedEventArgs e)
        {
            lblsuccess.Visible = false;
            timer1.Enabled=false;
        }

 if (saved == true)
            {
                //data saved - show label and then make visible = false

                timer1.Enabled=true;
                lblsuccess.Visible = true;
                lblsuccess.Text = "Visit saved";
             }
