MessageBox实现自动延时关闭

  public partial class MessageForm : Form
    {
         int t;
         string txt;
        /// <summary>
        /// 自定义弹窗
        /// </summary>
        /// <param name="time">窗体消失时间</param>
        /// <param name="text">窗体提示内容</param>
        public MessageForm(int time, string text)
        {
            t = time;
            txt = text;
            InitializeComponent();
        }
        private void timer1_Tick(object sender, EventArgs e)
        {
            this.Close();
        }

        private void MessageForm_Load(object sender, EventArgs e)
        {
        
            timer1.Interval = t;
            timer1.Enabled = true;
            MessageBox.Show(this, txt, "提示");
        }
    }

new MessageForm(3000, "输入参数有误").Show();
