Question

我正在为RFID阅读器开发应用程序。我有一个按钮，其中包含以下操作：

private void btnWrite_Click(object sender, EventArgs e)
        {
            this.CheckPort = true;
            this.DetectCOMPort();
            bool readerOK = this.IsReaderConnected(this.lblCom.Text);
            bool flag = !readerOK;
            if (flag)
            {
                this.CheckPort = true;
                this.DetectCOMPort();
            }
            else
            {
                byte[] raspunsCitire = this.CitesteTag(this.lblCom.Text);
                flag = raspunsCitire == null;
                if (flag)
                {
                    MessageBox.Show("The label couldn't be read!");
                }
                else
                {
                    string scrisInTag = this.FormateazaCitire(raspunsCitire);
                    string[] campuriScrise = this.DecompileazaMesaj(scrisInTag, '|');
                    this.btnValid.Enabled = true;
                    this.txtEvenim.Enabled = true;
                    this.txtEvenim.Text = campuriScrise[0];
                    this.txtNume.Enabled = true;
                    this.txtNume.Text = campuriScrise[1];
                    this.txtPrenume.Enabled = true;
                    this.txtPrenume.Text = campuriScrise[2];
                    this.txtComp.Enabled = true;
                    this.txtComp.Text = campuriScrise[3];
                    this.txtFunc.Enabled = true;
                    this.txtFunc.Text = campuriScrise[4];
                    this.txtTit.Enabled = true;
                    this.txtTit.Text = campuriScrise[5];
                    this.Refresh();
                }
            }
        }

我想要的是读取标签每2秒重复一次，而不是显示MessageBox.Show("The label couldn't be read!");。对于另一种情况，当一个标签被读取时，我希望这个过程停止让我们说20秒，然后20秒后再开始阅读，每2秒钟。有可能以某种方式做到这一点？提前谢谢！

您是否考虑过计时器控制？

Timer timer = new Timer();

timer.Tick += new EventHandler(timer_Tick); // Everytime timer ticks, timer_Tick will be called
timer.Interval = (1000) * (10);             // Timer will tick evert 10 seconds
timer.Enabled = true;                       // Enable the timer
timer.Start();

C＃重复按钮动作
