Question

我正在用c＃silverlight写扫雷游戏 1.如何在此应用程序中添加计数器（仅计数秒数）？ 2.当应用程序进入后台时（中间按钮，搜索按钮，来电等），如何停止计数器？ 3.当WP7关闭我的申请流程时，我该怎么办？例如，将当前游戏保存到隔离存储。

1）您需要使用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();                              // Start the time

void timer_Tick(object sender, EventArgs e)
        {
           //Do something
        }

2）您需要处理OnNavigatedFrom事件：

private void Application_Deactivated(object sender, DeactivatedEventArgs e)
{
    //Do something
}

3）这里有4个有用的事件：

    // Code to execute when the application is launching (eg, from Start)
// This code will not execute when the application is reactivated
private void Application_Launching(object sender, LaunchingEventArgs e)
{
    //Do something
}

// Code to execute when the application is activated (brought to foreground)
// This code will not execute when the application is first launched
private void Application_Activated(object sender, ActivatedEventArgs e)
{
    //Do something
}

// Code to execute when the application is deactivated (sent to background)
// This code will not execute when the application is closing
private void Application_Deactivated(object sender, DeactivatedEventArgs e)
{
    //Do something
}

// Code to execute when the application is closing (eg, user hit Back)
// This code will not execute when the application is deactivated
private void Application_Closing(object sender, ClosingEventArgs e)
{
    //Do something
}
