1、創(chuàng)建新項(xiàng)目

使用Visual Studio 2022創(chuàng)建新項(xiàng)目，如圖點(diǎn)擊創(chuàng)建新項(xiàng)目：

選擇WPF應(yīng)用(.NET Framework)：

配置新項(xiàng)目，如圖：

隨便寫(xiě)幾個(gè)WPF默認(rèn)樣式控件：

2、安裝 MahApps.Metro

點(diǎn)擊工具->NuGet包管理器->管理解決方案的NuGet程序包，如圖所示：

搜索MahApps，點(diǎn)擊第一個(gè)，安裝即可：

點(diǎn)擊確認(rèn)，如圖：

安裝完成，如圖所示：

3、App.xaml修改代碼

在App.xaml中修改如下代碼：

<Application x:Class="FMSH_NVM_WPF.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:FMSH_NVM_WPF"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <!-- MahApps.Metro resource dictionaries. Make sure that all file names are Case Sensitive! -->
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
                <!-- Theme setting -->
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Themes/Light.Blue.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

如圖所示：

此時(shí)，重新生成并運(yùn)行程序，窗體內(nèi)部的控件樣式已經(jīng)發(fā)生改變，如圖：

4、MainWindow.xaml修改代碼

在MainWindow.xaml中修改如下代碼：

<mah:MetroWindow x:Class="FMSH_NVM_WPF.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:mah="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:FMSH_NVM_WPF"
        mc:Ignorable="d"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Button Content="Button" HorizontalAlignment="Left" Margin="226,67,0,0" VerticalAlignment="Top"/>
        <Button Content="Button" HorizontalAlignment="Left" Margin="454,86,0,0" VerticalAlignment="Top"/>
        <Calendar HorizontalAlignment="Left" Margin="136,149,0,0" VerticalAlignment="Top"/>
        <TabControl Margin="390,170,10,22">
            <TabItem Header="TabItem">
                <Grid Background="#FFE5E5E5"/>
            </TabItem>
            <TabItem Header="TabItem">
                <Grid Background="#FFE5E5E5"/>
            </TabItem>
        </TabControl>

    </Grid>
</mah:MetroWindow>

如圖所示：

打開(kāi)文件MainWindow.xaml.cs，修改代碼如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using MahApps.Metro.Controls;

namespace FMSH_NVM_WPF
{
    /// <summary>
    /// MainWindow.xaml 的交互邏輯
    /// </summary>
    public partial class MainWindow : MetroWindow
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }
}

如圖所示：

保存后重新編譯運(yùn)行，窗體的樣式已經(jīng)發(fā)生改變，如圖所示：
