一、先看效果

二、本文背景

YouTube Design com WPF 大神处习得，简单的计算器布局界面 + 简单动画，使用的开源 C# WPF控件库 MaterialDesignInXAML ，本站曾有介绍：开源C# WPF控件库《MaterialDesignInXAML》。

三、代码实现

3.1 添加Nuget库

站长使用.Net Core 3.1创建的WPF工程，创建“Calculator”解决方案后，需要添加两个Nuget库：MaterialDesignThemes和MaterialDesignColors，上图的效果是使用该控件库实现的，非常强大。

3.2 工程结构

不需要截图，只修改了两个文件，App.xaml添加MD控件样式，MainWindow主窗口实现效果。

3.3 App.xaml引入MD控件样式

&lt;Application x:Class=&#34;Calculator.App&#34;             xmlns=&#34;http://schemas.microsoft.com/winfx/2006/xaml/presentation&#34;             xmlns:x=&#34;http://schemas.microsoft.com/winfx/2006/xaml&#34;             xmlns:local=&#34;clr-namespace:Calculator&#34;             StartupUri=&#34;MainWindow.xaml&#34;&gt;    &lt;Application.Resources&gt;        &lt;ResourceDictionary&gt;            &lt;ResourceDictionary.MergedDictionaries&gt;                &lt;ResourceDictionary Source=&#34;pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml&#34; /&gt;                &lt;ResourceDictionary Source=&#34;pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml&#34; /&gt;            &lt;/ResourceDictionary.MergedDictionaries&gt;            &lt;!--PRIMARY--&gt;            &lt;SolidColorBrush x:Key=&#34;PrimaryHueLightBrush&#34; Color=&#34;#349fda&#34;/&gt;            &lt;SolidColorBrush x:Key=&#34;PrimaryHueLightForegroundBrush&#34; Color=&#34;#FF777777&#34;/&gt;            &lt;SolidColorBrush x:Key=&#34;PrimaryHueMidBrush&#34; Color=&#34;#FF222222&#34;/&gt;            &lt;SolidColorBrush x:Key=&#34;PrimaryHueMidForegroundBrush&#34; Color=&#34;#DDDDDD&#34;/&gt;            &lt;SolidColorBrush x:Key=&#34;PrimaryHueDarkBrush&#34; Color=&#34;#FF000000&#34;/&gt;            &lt;SolidColorBrush x:Key=&#34;PrimaryHueDarkForegroundBrush&#34; Color=&#34;#FFFFFF&#34;/&gt;            &lt;!--ACCENT--&gt;            &lt;SolidColorBrush x:Key=&#34;SecondaryAccentBrush&#34; Color=&#34;#FFD14C25&#34;/&gt;            &lt;SolidColorBrush x:Key=&#34;SecondaryAccentForegroundBrush&#34; Color=&#34;#FFFFFF&#34;/&gt;        &lt;/ResourceDictionary&gt;    &lt;/Application.Resources&gt;&lt;/Application&gt;

3.4 主窗体

MainWindow.xaml，整体布局，看上图加上下面的界面代码，本文基本就是布局 + 简单动画，全在这个界面，直接看代码吧，不细说了：

&lt;Window x:Class=&#34;Calculator.MainWindow&#34;        xmlns=&#34;http://schemas.microsoft.com/winfx/2006/xaml/presentation&#34;        xmlns:x=&#34;http://schemas.microsoft.com/winfx/2006/xaml&#34;

           &lt;ObjectAnimationUsingKeyFrames Storyboard.TargetProperty=&#34;(UIElement.Visibility)&#34; Storyboard.TargetName=&#34;grid&#34;&gt;                &lt;DiscreteObjectKeyFrame KeyTime=&#34;0&#34; Value=&#34;{x:Static Visibility.Visible}&#34;/&gt;                &lt;DiscreteObjectKeyFrame KeyTime=&#34;0:0:1.3&#34; Value=&#34;{x:Static Visibility.Visible}&#34;/&gt;                &lt;DiscreteObjectKeyFrame KeyTime=&#34;0:0:1.5&#34; Value=&#34;{x:Static Visibility.Collapsed}&#34;/&gt;            &lt;/ObjectAnimationUsingKeyFrames&gt;            &lt;DoubleAnimationUsingKeyFrames Storyboard.TargetProperty=&#34;(UIElement.Opacity)&#34;

               &lt;EasingDoubleKeyFrame KeyTime=&#34;0:0:1.5&#34; Value=&#34;0&#34;/&gt;            &lt;/DoubleAnimationUsingKeyFrames&gt;        &lt;/Storyboard&gt;    &lt;/Window.Resources&gt;    &lt;Window.Triggers&gt;
