WPF 窗体设置亚克力效果
框架使用大于等于.NET40。
Visual Studio 2022。
项目使用 MIT 开源许可协议。
WindowAcrylicBlur 设置亚克力颜色。
Opacity 设置透明度。


实现代码
1） 准备WindowAcrylicBlur.cs如下：
usingSystem;
usingSystem.Runtime.InteropServices;
usingSystem.Windows;
usingSystem.Windows.Interop;
usingSystem.Windows.Media;
usingMicrosoft.Win32;
usingMicrosoft.Windows.Shell;

int.TryParse(str,outrevision);

returnnewVersion(major,minor,build,revision);
}

finally

}
}

2） 使用AcrylicBlurWindowExample.xaml如下：
<Windowx:Class="WPFDevelopers.Samples.ExampleViews.AcrylicBlurWindowExample"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WPFDevelopers.Samples.ExampleViews"
xmlns:wpfdev="https://github.com/WPFDevelopersOrg/WPFDevelopers"
mc:Ignorable="d"WindowStartupLocation="CenterScreen"
ResizeMode="CanMinimize"
Title="Login"Height="350"Width="400">

</wpfdev:WindowChrome.WindowChrome>
<wpfdev:WindowAcrylicBlur.WindowAcrylicBlur>
<wpfdev:WindowAcrylicBlurBlurColor="AliceBlue"Opacity="0.2"/>
</wpfdev:WindowAcrylicBlur.WindowAcrylicBlur>
<Grid>
<Grid.RowDefinitions>
<RowDefinitionHeight="40"/>
<RowDefinition/>
</Grid.RowDefinitions>
<StackPanelHorizontalAlignment="Right"

Grid.Column="1"
wpfdev:WindowChrome.IsHitTestVisibleInChrome="True">

<PathWidth="10"Height="10"
HorizontalAlignment="Center"
VerticalAlignment="Center"
Data="{DynamicResourcePathMetroWindowClose}"
Fill="Red"
Stretch="Fill"/>
</Button>
</StackPanel>
<StackPanelGrid.Row="1"Margin="40,0,40,0"
wpfdev:WindowChrome.IsHitTestVisibleInChrome="True">
<ImageSource="/WPFDevelopers.ico"Width="80"Height="80"/>
<TextBoxwpfdev:ElementHelper.IsWatermark="True"wpfdev:ElementHelper.Watermark="账户"Margin="0,20,0,0"Cursor="Hand"/>
<PasswordBoxwpfdev:ElementHelper.IsWatermark="True"wpfdev:ElementHelper.Watermark="密码"Margin="0,20,0,0"Cursor="Hand"/>
<Buttonx:Name="LoginButton"
Content="登录"
Margin="0,20,0,0"
Style="{StaticResourcePrimaryButton}"/>
<GridMargin="02000">
<TextBlockFontSize="12">
<HyperlinkForeground="Black"TextDecorations="None">忘记密码</Hyperlink>
</TextBlock>
<TextBlockFontSize="12"HorizontalAlignment="Right"Margin="00-10">
<HyperlinkForeground="#4370F5"TextDecorations="None">注册账号</Hyperlink>
</TextBlock>
</Grid>
</StackPanel>

</Grid>
</Window>
3） 使用AcrylicBlurWindowExample.xaml.cs如下：
usingSystem.Windows;
usingSystem.Windows.Input;
usingWPFDevelopers.Samples.Helpers;

namespaceWPFDevelopers.Samples.ExampleViews
{
///<summary>
///AcrylicBlurWindowExample.xaml的交互逻辑
///</summary>
publicpartialclassAcrylicBlurWindowExample:Window
{
publicAcrylicBlurWindowExample()
{
InitializeComponent();
}
publicICommandCloseCommand=>newRelayCommand(obj=>
{
Close();
});
}
}实现效果
