C#中怎么实现响应式布局

本篇文章为大家展示了C#中怎么实现响应式布局，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

添加Nuget库

使用 .Net Core 3.1 创建名为 “ResponsiveLayout” 的WPF解决方案，添加两个Nuget库：MaterialDesignThemes和MaterialDesignColors。

MaterialDesign控件库 

3.2 工程结构

3个文件变动：

1. App.xaml：添加MD控件样式

2. MainWindow.xaml：主窗口实现效果

3. MainWindow.xaml.cs：主窗口后台实现抽屉菜单开和闭

3.3 App.xaml引入MD控件样式

关键样式引用代码

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

3.4 主窗体 MainWindow.xaml

全部代码，菜单及右侧布局

<Window x:Class="ResponsiveLayout.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:ResponsiveLayout"
        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Window.Resources>
        <Storyboard x:Key="CloseMenu">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(Grid.Width)" Storyboard.TargetName="grid">
                <EasingDoubleKeyFrame KeyTime="0" Value="200"/>
                <EasingDoubleKeyFrame KeyTime="0:0:0.4" Value="70"/>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>
        <Storyboard x:Key="OpenMenu">
            <DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(Grid.Width)" Storyboard.TargetName="grid">
                <EasingDoubleKeyFrame KeyTime="0" Value="70"/>
                <EasingDoubleKeyFrame KeyTime="0:0:0.4" Value="200"/>
            </DoubleAnimationUsingKeyFrames>
        </Storyboard>
    </Window.Resources>
    <Grid>
        <Grid>
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="auto"/>
                <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <Grid Background="#FFCBCBCB" Grid.Column="1">
                <Grid Margin="0 20 0 0" Background="#FFEEEEEE">
                    <Grid Height="100" Background="#FFEEEEEE" VerticalAlignment="Top" HorizontalAlignment="Stretch" Margin="10">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="*"/>
                            <ColumnDefinition Width="*"/>
                        </Grid.ColumnDefinitions>

                        <Border BorderBrush="White" BorderThickness="0 0 1 0" Grid.Column="0">
                            <TextBlock FontSize="30" Text="R$ 860,90" Foreground="Black" Margin="15"/>
                        </Border>
                        <Border BorderBrush="White" BorderThickness="0 0 1 0" Grid.Column="1">
                            <TextBlock FontSize="30" Text="R$ 750,90" Foreground="Black" Margin="15"/>
                        </Border>
                        <Border BorderBrush="White" BorderThickness="0 0 1 0" Grid.Column="2">
                            <TextBlock FontSize="30" Text="R$ 60,90" Foreground="Black" Margin="15"/>
                        </Border>
                        <Border BorderBrush="White" BorderThickness="0 0 1 0" Grid.Column="3">
                            <TextBlock FontSize="30" Text="R$ 865,90" Foreground="Black" Margin="15"/>
                        </Border>
                    </Grid>
                </Grid>
            </Grid>
            <Grid x:Name="grid" Width="200" Background="#FF6C6C8D" RenderTransformOrigin="0.5,0.5" Grid.Column="0">
                <Button x:Name="button" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="10" Style="{StaticResource MaterialDesignFlatButton}" Click="Button_Click">
                    <materialDesign:PackIcon Kind="Menu" Foreground="White"/>
                </Button>
            </Grid>
        </Grid>
    </Grid>
</Window>

3.5 MainWindow.xaml.cs

关键代码，简单的菜单开、闭动画播放

private void Button_Click(object sender, RoutedEventArgs e)
{
    if (MenuClosed)
    {
        Storyboard openMenu = (Storyboard)button.FindResource("OpenMenu");
        openMenu.Begin();
    }
    else
    {
        Storyboard closeMenu = (Storyboard)button.FindResource("CloseMenu");
        closeMenu.Begin();
    }

    MenuClosed = !MenuClosed;
}
