Question

我正在进行记忆游戏，我需要设置一个计时器来重置de images，如果它们不匹配但是它不能将图片重新设置为隐藏：

//set images
if (clickedLabel != null)
{
    var Index = Convert.ToInt32(clickedLabel.Tag);
    clickedLabel.Image = icons[Index];

    //Check first clicked
    if (firstClicked == null)
    {
        firstClicked = clickedLabel;
        return;
    }

    secondClicked = clickedLabel;

    timer1.Start();
}

方法timer1_Tick：

//Timer
private void timer1_Tick(object sender, EventArgs e)
{
    timer1.Stop();

    firstClicked = null;
    secondClicked = null;
}

这可能有效：

class YourClass
{
    System.Timers.Timer aTimer;
    void YourMethod()
    {
        //code
        if (clickedLabel != null)
        {
            var Index = Convert.ToInt32(clickedLabel.Tag);
            clickedLabel.Image = icons[Index];

            //Check first clicked
            if (firstClicked == null)
            {
            firstClicked = clickedLabel;
            return;
        }

        secondClicked = clickedLabel;

        SetTimer();
    }

    private static void SetTimer ()
    {
        //System.Timers.Timer aTimer; at the beginning of your class
        aTimer = new System.Timers.Timer (2000); //the time you want in milliseconds
        aTimer.Elapsed += OnTimedEvent;
        aTimer.AutoReset = false;
        aTimer.Enabled = true;
    }
}

AutoReset设置为false将使Elapsed事件仅触发一次。然后，你在那个事件中做你想做的事。

private static void OnTimedEvent (Object source, ElapsedEventArgs e) 
{
    firstClicked = null;
    secondClicked = null;
}

当您不再需要时，您可能希望在aTimer上使用Stop和Dispose方法。

在发布问题时，您也应该更加具体，以确保获得所需的帮助：）
