C#变量不会更新

Question

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.这非常好,它向我展示了Temp.来自我的PS3的CPU/GPU.

现在我已经实现了一个"刷新"按钮,它启动所有x秒的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();
        }

所以当我按下连接按钮时,这个"get_psdata"只能在第一次工作.(连接按钮直接启动"get_psdate"功能,而刷新按钮则略有不同,就像您稍后会看到的那样......)

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;
            }
        }

为了测试,我在"get_psdata"函数中添加了一个Messagebox.Show来查看它是否全部运行x秒...是的,它是我的计时器:

        //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!");
        }
    }

所以我确信代码将运行所有x秒但标签仅在我按下连接按钮时更新,但是如果我在连接B_set按钮后启动计数器则不会.

"get_psdata"中的变量未显示更新的值.他们只显示第一个"获取"的结果.他们为什么不显示最新结果？

如果我在新的 winforms 屏幕中使用你的代码，一切都会很好。不过，我确实对 get_psdata 使用了以下实现。

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();
}

以 1 秒为间隔，每秒都会在屏幕上显示新值。你能试试这个代码吗？如果这工作正常，那么问题可能在于 PS3 对象不刷新其内部？
