WPF+MVVM案例实战（三）- 动态数字卡片效果实现

1、创建项目

打开 VS2022 ，新建项目 Wpf_Examples，创建各层级文件夹，安装 CommunityToolkit.Mvvm 和 Microsoft.Extensions.DependencyInjectio NuGet包,完成MVVM框架搭建。搭建完成后项目层次如下图所示：
在这里插入图片描述
这里如何实现 MVVM 框架可以参考本人像 MvvmLight 一样使用 CommunityToolkit.Mvvm 工具包的文章

2、整理项目

1、项目目录层级

在前面该案例前，已经发布了两个案例，为了后续不断推出的新案例，我们先将项目整理成一个整体，做成整套案例系统,后续所有的案例都在该项目上迭代更新。目前先做简单的归纳处理，我们把所有案例都单独放在一个窗体，主窗体做按钮菜单，每个案例通过弹窗方式呈现。基于以上整理后得到系统文件层级分布如下所示：

2、案例代码实现

1、主界面菜单实现

1、MainWindow.xaml 代码

<Window x:Class="Wpf_Examples.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:converter="clr-namespace:Wpf_Examples.Converters"xmlns:local="clr-namespace:Wpf_Examples"xmlns:cc="clr-namespace:CustomControlLib;assembly=CustomControlLib"DataContext="{Binding Source={StaticResource Locator},Path=Main}"mc:Ignorable="d"Title="MainWindow" Height="450" Width="800"><Grid><WrapPanel><Button Width="120" Height="30" FontSize="18" Content="图片按钮" Command="{Binding ButtonClickCmd}" CommandParameter="{Binding RelativeSource={RelativeSource Mode=Self},Path=Content}" Margin="8"/><Button Width="120" Height="30" FontSize="18" Content="LED效果灯" Command="{Binding ButtonClickCmd}" CommandParameter="{Binding RelativeSource={RelativeSource Mode=Self},Path=Content}" Margin="8"/><Button Width="120" Height="30" FontSize="18" Content="动态数字卡" Command="{Binding ButtonClickCmd}" CommandParameter="{Binding RelativeSource={RelativeSource Mode=Self},Path=Content}" Margin="8"/></WrapPanel></Grid>
</Window>
