In the development of C# WPF application, window effects are an important means to improve user experience. This article will introduce several commonly used window effects and their implementation methods, including animation, shadows, blur effects, etc.
1. Animation effect
WPF provides powerful animation support, and can achieve various animation effects through Storyboard and animation classes.
1.1 Fade effect
Fade effect is one of the most common animation effects, and can be implemented with the following code:
<Window x:Class=""
xmlns="/winfx/2006/xaml/presentation"
xmlns:x="/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Button Content="Click me">
<>
<EventTrigger RoutedEvent="">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation ="Opacity"
From="0" To="1" Duration="0:0:2"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</>
</Button>
</Grid>
</Window>1.2 Scaling effect
The zoom effect can make interface elements more vivid when loading. Here is an example of a zoom animation:
<Window x:Class=""
xmlns="/winfx/2006/xaml/presentation"
xmlns:x="/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Button Content="Click me">
<>
<EventTrigger RoutedEvent="">
<BeginStoryboard>
<Storyboard>
<DoubleAnimation =""
From="0" To="1" Duration="0:0:2"/>
<DoubleAnimation =""
From="0" To="1" Duration="0:0:2"/>
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</>
<>
<ScaleTransform />
</>
</Button>
</Grid>
</Window>2. Shadow effect
The shadow effect can increase the three-dimensionality of the interface, and DropShadowEffect in WPF can be used to achieve shadow effect.
<Window x:Class=""
xmlns="/winfx/2006/xaml/presentation"
xmlns:x="/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<Button Content="Click me" Width="100" Height="50">
<>
<DropShadowEffect BlurRadius="10" Direction="330" ShadowDepth="5" Color="Gray"/>
</>
</Button>
</Grid>
</Window>
3. Blur effect
On Windows 10 and Windows 11, the system-provided API can be used to achieve the blur effect of windows.
3.1 Windows 10 Blur Effect
For Windows 10, you can use the SetWindowCompositionAttribute method to achieve the blur effect.
public static void EnableBlur(Window window)
{
var helper = new WindowInteropHelper(window);
var accent = new AccentPolicy
{
AccentState = AccentState.ACCENT_ENABLE_BLURBEHIND,
AccentFlags = | | | ,
GradientColor = 0x00FFFFFF
};
(, ref accent);
}
3.2 Windows 11 Blur Effect
For Windows 11, you can use the DwmSetWindowAttribute method to achieve blur effect.
public static void EnableMica(Window window)
{
var helper = new WindowInteropHelper(window);
varmica = ();
mica?.SetMica(window);
}
4. Acrylic effect
Acrylic effect is a modern UI effect introduced in Windows 10 and Windows 11, and can be achieved through third-party libraries such as XamlFlair.
<Window x:Class=""
xmlns:xf="clr-namespace:XamlFlair;assembly="
Title="MainWindow" Height="350" Width="525">
<Grid xf:="{StaticResource FadeIn}" />
</Window>
in conclusion
By using WPF's animation, shadow, blur and acrylic effects, you can significantly improve the user experience of your application. These special effects not only make the interface more beautiful, but also improve the user's interactive experience. Hopefully, the sample code provided in this article can help you implement these special effects in development.
