How can I create and show a popup window at a specific time in WPF? What I mean how to display the window on the side of system tray.

推荐答案

如果您想在特定的小时/秒/分钟(或计算多少小时/还剩几秒/分钟，直到您的特定时间到来).

You could use a timer if you're trying to make the thing popup in a certain number of hours/seconds/minutes (or work out how many hours/seconds/minutes are left until your specific time comes around).

private System.Windows.Threading.DispatcherTimer popupTimer;

// Whatever is going to start the timer - I've used a click event
private void OnClick(object sender, RoutedEventArgs e)
{
    popupTimer = new System.Windows.Threading.DispatcherTimer();

    // Work out interval as time you want to popup - current time
    popupTimer.Interval = specificTime - DateTime.Now;
    popupTimer.IsEnabled = true;
    popupTimer.Tick += new EventHandler(popupTimer_Tick);
}

void popupTimer_Tick(object sender, EventArgs e)
{
    popupTimer.IsEnabled = false;
    // Show popup
    // ......
}

<小时>

好的，所以你也想知道如何做一个通知弹出类型的事情，这可能是 CodeProject 可能会有所帮助.
