在windows phone 8中每半秒更新文本块的文本

Question

我想随机选择一些我的数组。然后我将它显示在一个文本块中。我想每秒都做。如何每秒更新我的文本块？请帮助我。

Answer 1

创建一个调度程序计时器，并为每个ticks更新您的textbock。

number = 0 
dispatcherTimer = new System.Windows.Threading.DispatcherTimer(); 
dispatcherTimer.Tick += new EventHandler(dispatcherTimer_Tick); 
dispatcherTimer.Interval = new TimeSpan(0,0,1); 
dispatcherTimer.Start(); 

private void dispatcherTimer_Tick(object sender, EventArgs e) 
{ 
    //if you use binding and mvvm 
    this.Text = number.tostring(); 
    //if you don't use binding 
    yourTextblock.Text = number.toString(); 
    number ++; 
}

创建调度员计时器和每半秒更新文本框中

int number=0; 
    private DispatcherTimer _timer; 
    public sample() 
    { 
     InitializeComponent(); 
     _timer = new DispatcherTimer(); 
     _timer.Interval = new TimeSpan(0, 0, 0,0,500); 
     _timer.Tick += _timer_Tick; 
     _timer.Start(); 
    } 
    void _timer_Tick(object sender, EventArgs e) 
    { 
     number++; 
     yourTextblock.Text = number.toString(); 
    }
