1. 本文背景
继续 MaterialDesignThemes 开源控件库学习，尤其是它的图标组件，本文设计的音乐播放器主界面设计使用该组件较多。
2. 代码实现
使用 .NET CORE 3.1 创建名为 “Player” 的WPF模板项目，添加1个Nuget库：MaterialDesignThemes.3.1.0-ci981。
解决方案主要文件目录组织结构：
- Player
- App.xaml
- MainWindow.xaml
- MainWindow.xaml.cs
2.1 App.xaml文件引入样式
文件【App.xaml】，在 StartupUri 中设置启动的视图【MainWindow.xaml】，并在【Application.Resources】节点增加 MaterialDesignThemes库的样式文件：
<Application x:Class="Player.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Player"
StartupUri="MainWindow.xaml">
<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.Blue.xaml" />
<ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Indigo.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
2.2 MainWindow.xaml音乐播放器主窗体
文件【MainWindow.xaml】，设计主界面，源码如下：
<Window x:Class="Player.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"

简单说明：
- 界面中按钮使用开源控件库MD的【PackIcon】组件，统一风格使用了自定义前景色【Foreground】。
- 列表控件【ListView】用于展示音乐播放列表，方便演示，每一项写死的，实际使用需要封装成模板，方便MVVM数据绑定。
- 列表控件【ListView】的竖直滚动条样式进行了修改，可看资源定义，改为了整体和黑色背景比较搭配的白色。
下面是后台代码：文件【MainWindow.xaml.cs】，关闭窗体、窗体移动、上一首及下一首按钮简单点击等事件处理，因为是演示事例，所以写的简单。
using System.Windows;
using System.Windows.Input;
namespace Player
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void ButtonFechar_Click(object sender, RoutedEventArgs e)
{
Application.Current.Shutdown();
}
private void Proxima_Click(object sender, RoutedEventArgs e)
{
if (c1.Offset >= 0)
{
c1.Offset -= 0.01;
c2.Offset -= 0.01;
}
else
{
c1.Offset = 1;
c2.Offset = 0.89;
}
}
private void Anterior_Click(object sender, RoutedEventArgs e)
{
if (c2.Offset <= 1)
{
c1.Offset += 0.01;
c2.Offset += 0.01;
}
else
{
c1.Offset = 0.11;
c2.Offset = 0;
}
}
private void MoveWindow_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
DragMove();
}
}
}
