1、设置窗体TopMost属性

private DispatcherTimer timer;

public Window1()
{
    InitializeComponent();
    Loaded += new RoutedEventHandler(Window1_Loaded);
}
 
void Window1_Loaded(object sender, RoutedEventArgs e)
{
    timer = new DispatcherTimer();
    timer.Interval = TimeSpan.FromSeconds(1);
    timer.Tick += timer1_Tick;
    timer.Start();　　

　 //....

　 //timer.Stop();
}
 
private void timer1_Tick(object sender, EventArgs e)
{
    //定时处理

　 this.TopMost = true;
}
