1. 本文背景

繼續 MaterialDesignThemes 開源控件庫學習，尤爲是它的圖標組件，本文設計的音樂播放器主界面設計使用該組件較多。

2. 代碼實現

使用 .NET CORE 3.1 建立名爲 「Player」 的WPF模板項目，添加1個Nuget庫：MaterialDesignThemes.3.1.0-ci981。

解決方案主要文件目錄組織結構：

• Player
  • App.xaml
  • MainWindow.xaml
    • MainWindow.xaml.cs

2.1 App.xaml文件引入樣式

文件【App.xaml】，在 StartupUri 中設置啓動的視圖【MainWindow.xaml】，並在【Application.Resources】節點增長 MaterialDesignThemes庫的樣式文件：

<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音樂播放器主窗體

文件【MainWindow.xaml】，設計主界面，源碼以下：

<Window x:Class="Player.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"

簡單說明：

1. 界面中按鈕使用開源控件庫MD的【PackIcon】組件，統一風格使用了自定義前景色【Foreground】。
2. 列表控件【ListView】用於展現音樂播放列表，方便演示，每一項寫死的，實際使用須要封裝成模板，方便MVVM數據綁定。
3. 列表控件【ListView】的豎直滾動條樣式進行了修改，可看資源定義，改成了總體和黑色背景比較搭配的白色。

下面是後臺代碼：文件【MainWindow.xaml.cs】，關閉窗體、窗體移動、上一首及下一首按鈕簡單點擊等事件處理，由於是演示事例，因此寫的簡單。

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();
        }
    }
}
