如何在更改变量时更新文本标签

Question

我有点新的编程，我试图重新创建candybox（一些互动网站） 在Windows窗体应用程序中。我有一个名为糖果的变量，以及每秒向变量糖果添加一个的计时器，我试过把label.text =＆＃34; candy：＆＃34; + candy.ToString（）;在那种方法中它似乎没有用，任何人都可以提供帮助吗？

代码：

public partial class Form1 : Form
{
    public int candy { get; set; }
    public int lollipop { get; set; }

    public Form1(int value, int lollipop)
    {
        this.candy = value;
        this.lollipop = lollipop;
    }
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        label1.Text = "candy: 0";
        button2.Enabled = false;
        button2.Visible = false;
        label2.Visible = false;

        timer.Elapsed += new System.Timers.ElapsedEventHandler(this.TimerHandler);
        timer.Start();

    }

    private void button1_Click(object sender, EventArgs e)
    {
        candy += 2;
        UpdateCandy(candy, lollipop);
        label2.Text = "lollipops" + lollipop.ToString();
        if (candy > 9)
        {
            button2.Enabled = true;
            button2.Visible = true;
        }
    }
    private void button2_Click(object sender, EventArgs e)
    {
        if (candy <= 10)
        {
            button2.Enabled = false;
        }
        candy -= 10;
        lollipop += 1;
        UpdateCandy(candy, lollipop);
        label2.Text = "lollipops" + lollipop.ToString();
        label2.Visible = true;
    }
    System.Timers.Timer timer = new System.Timers.Timer(1000);

    private void TimerHandler(object sender, System.Timers.ElapsedEventArgs e)
    {
        DateTime start;
        TimeSpan elapsed = TimeSpan.MaxValue;


        while (elapsed.TotalSeconds > 1.0)
        {
            start = DateTime.Now;

            candy += 1;


            elapsed = DateTime.Now - start;
        }
        timer.Interval = 1000 - elapsed.TotalMilliseconds;
        timer.Start();

    }

    public void Form1_Shown(object sender, EventArgs e)
    {
        timer.Elapsed += new System.Timers.ElapsedEventHandler(this.TimerHandler);
        timer.Start();
    }
    private void UpdateCandy(int candy, int lollipop)
    {
        label1.Text = "candy: " + candy.ToString();
        label2.Text = "lollipops" + lollipop.ToString();
    }


}

我正在使用visual studio 2012（如果这些信息有任何帮助）
