您可以在窗口loaded事件上应用StoryBoard，以淡化您的窗口。这应该为你工作 -

<Window.Triggers> 
    <EventTrigger RoutedEvent="Window.Loaded"> 
     <BeginStoryboard> 
      <Storyboard> 
       <DoubleAnimation Storyboard.TargetProperty="(Window.Opacity)" 
           From="0.0" To="1.0" Duration="0:0:1" 
           AutoReverse="False"/> 
      </Storyboard> 
     </BeginStoryboard> 
    </EventTrigger> 
</Window.Triggers> 

你也可以在代码中做背后的窗口loaded事件处理程序，如果你不想做在XAML -

private void Window_Loaded(object sender, RoutedEventArgs e) 
    { 
     DoubleAnimation animation = new DoubleAnimation(0, 1, 
            (Duration)TimeSpan.FromSeconds(1)); 
     this.BeginAnimation(UIElement.OpacityProperty, animation); 
    }
