C# 变量不会更新

我正在编写一个 C# 程序来显示 PS3 的 CPU/GPU 温度。有一个连接按钮。这真的很好，它向我展示了 PS3 的 CPU/GPU 的温度。

现在我已经实现了一个"刷新"按钮，它为所有 x 秒启动一个计时器来执行此操作：

public void get_psdata()
        {
            //Get data from PS3
            cputemp = PS3.GetTemperatureCELL();
            gputemp = PS3.GetTemperatureRSX();
            psversion = PS3.GetFirmwareVersion();
            psversiontype = PS3.GetFirmwareType();
            //Set data into Var
            L_cputemp_show.Text = cputemp;
            L_gputemp_show.Text = gputemp;
            L_firmware_show.Text = psversion;
            L_type_show.Text = psversiontype;
            //Update Label
            L_cputemp_show.Refresh();
        }

所以这个"get_psdata"只在我第一次按下连接按钮时起作用。(连接按钮直接启动"get_psdate"功能，而刷新按钮的作用略有不同，就像你稍后看到的那样......

以下是运行get_psdata的代码：

//B_connect, Connect Button
        private void b_connect_Click(object sender, EventArgs e)
        {
            //Connect CCAPI to PS3 if Button clicked
            PS3.ConnectTarget(psip);
            //Check Connection
            if (PS3.SUCCESS(PS3.ConnectTarget(psip)))
            {
                //Show Status
                MessageBox.Show("Connected to: " + psip + "!");
                this.L_status_show.Text = "Connected!"; L_status_show.ForeColor = System.Drawing.Color.Green;
                //Call Function
                get_psdata();
            }
            else
            {
                //Show Status
                MessageBox.Show("Failed to Connect to: " + psip + "!");
                this.L_status_show.Text = "Not Connected!"; L_status_show.ForeColor = System.Drawing.Color.Red;
            }
        }

为了进行测试，我在"get_psdata"函数中添加了一个 Messagebox.Show 以查看它是否运行所有 x 秒...是的，它确实如此，这是我的计时器：

        //Function to set refresh delay
        public void refresh_delay()
        {
            MessageBox.Show("Delay set to " + refresh_int + " Seconds!");
            refresh_int = refresh_int * 1000; //Change to Miliseconds
            init_timer();
        }
        //Timer
        public Timer timer1;
        public void init_timer()
        {
            timer1 = new Timer();
            timer1.Tick += new EventHandler(timer1_Tick);
            timer1.Interval = refresh_int; // in miliseconds
            timer1.Start();
        }
        public void timer1_Tick(object sender, EventArgs e)
        {
            get_psdata();
        }

这就是启动我的计时器的原因：

    //B_set, Set refresh time button
    private void B_set_Click(object sender, EventArgs e)
    {
        //Check refresh Value
        refresh_string = TB_refresh.Text;
        //Check empty
        if (refresh_string != "")
        {
            //Check minimum
            refresh_int = Convert.ToInt32(TB_refresh.Text);
            if (refresh_int < 5)
            {
                DialogResult confirm = MessageBox.Show("This is not the delay you are looking for! 'r (I recommend to set it bigger then 5) 'r Continue with " + refresh_int + " Seconds?", "Realy dude?", MessageBoxButtons.YesNo);
                if (confirm == DialogResult.Yes)
                {
                    //Call Function
                    refresh_delay();
                }
            }
            else
            {
                //Call Function
                refresh_delay();
            }
        }
        else
        {
            MessageBox.Show("Please set refresh delay!");
        }
    }

所以我确定代码将运行所有 x 秒，但标签仅在我点击连接按钮时更新，但如果我在使用B_set按钮连接后启动计数器，则不会更新。

"get_psdata"中的变量未显示更新的值。它们只是显示第一个"获取"的结果。为什么他们不显示最新结果？

public void get_psdata()
{
    var rnd = new Random();
    //Set data into Var
    L_cputemp_show.Text = rnd.Next().ToString();
    L_gputemp_show.Text = rnd.Next().ToString();
    L_firmware_show.Text = rnd.Next().ToString();
    L_type_show.Text = rnd.Next().ToString();
    //Update Label
    L_cputemp_show.Refresh();
}
