1. 本文背景

同上篇文章《少量代码设计一个登录界面》，本篇介绍另一种登录界面设计风格。

2. 代码实现

使用 .NET CORE 3.1 创建名为 “Login” 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：

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="Login.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             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.DeepPurple.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

2.2 MainWindow.xaml 登录窗体

文件【MainWindow.xaml】，设计登录主界面，代码量很小，源码如下：

<Window x:Class="Login.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        mc:Ignorable="d"
        Title="Login" Height="400" Width="600" ResizeMode="NoResize" WindowStyle="None"
        AllowsTransparency="True" Background="Transparent" WindowStartupLocation="CenterScreen"
        MouseLeftButtonDown="MoveWindow_MouseLeftButtonDown">

    <Grid>
        <Rectangle RadiusY="8" RadiusX="8" Fill="White"/>
        <Rectangle Margin="310,0,0,0" RadiusX="8" RadiusY="8">
            <Rectangle.Fill>
                <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                    <GradientStop Color="#CC935E12" Offset="1"/>
                    <GradientStop Color="#CCEA4646"/>
                    <GradientStop Color="#CCB89128" Offset="0.566"/>
                </LinearGradientBrush>
            </Rectangle.Fill>
        </Rectangle>
        <StackPanel Margin="20,10,290,10">
            <Label Content="登录" FontFamily="Segoe UI Black" FontSize="24" Margin="0,10" VerticalAlignment="Top" HorizontalAlignment="Left"/>
            <StackPanel Orientation="Horizontal">
                <TextBlock HorizontalAlignment="Left" VerticalAlignment="Top" TextWrapping="Wrap" Foreground="#707070"><Run Text="你没有帐户吗？"/></TextBlock>
                <TextBlock HorizontalAlignment="Left" VerticalAlignment="Top" TextWrapping="Wrap" Foreground="#FF2468AC"><Run Text="创建一个帐户，"/></TextBlock>
            </StackPanel>
            <TextBlock HorizontalAlignment="Left" VerticalAlignment="Top" TextWrapping="Wrap" Foreground="#707070"><Run Text="那不需要撒谎。"/></TextBlock>
            <StackPanel Margin="0,15" Orientation="Horizontal">
                <materialDesign:PackIcon Kind="Account" VerticalAlignment="Center" Foreground="#707070"/>
                <TextBox materialDesign:HintAssist.Hint="账号" Width="250" Margin="5"/>
            </StackPanel>
            <StackPanel Orientation="Horizontal">
                <materialDesign:PackIcon Kind="Key" VerticalAlignment="Center" Foreground="#707070"/>
                <PasswordBox materialDesign:HintAssist.Hint="密码" Width="250" Margin="5"/>
            </StackPanel>
            <Grid>
                <CheckBox Content="记住我" Margin="5,10" Foreground="#707070"/>
                <Label Content="我忘了密码" HorizontalAlignment="Right" VerticalAlignment="Center" Margin="10" Foreground="#707070"/>
            </Grid>
            <Button HorizontalAlignment="Center" Content="登录" FontFamily="Impact" FontSize="18" Width="100" Background="#FF307CD6" BorderBrush="#FF307CD6"/>
            <StackPanel Orientation="Horizontal" Margin="10,35">
                <Label Content="第三方登录" Foreground="#707070" VerticalAlignment="Center"/>
                <Button HorizontalAlignment="Center" FontFamily="Impact" FontSize="18" Background="#FF3D56AC" BorderBrush="#FF3D56AC">
                    <materialDesign:PackIcon Kind="Wechat" VerticalAlignment="Center" Foreground="White"/>
                </Button>
                <Button HorizontalAlignment="Center" FontFamily="Impact" FontSize="18" Margin="15,0" Background="#FF01BAFF" BorderBrush="#FF01BAFF">
                    <materialDesign:PackIcon Kind="Qqchat" VerticalAlignment="Center" Foreground="White"/>
                </Button>
                <Button HorizontalAlignment="Center" FontFamily="Impact" FontSize="18" Background="#FFE05959" BorderBrush="#FFE05959">
                    <materialDesign:PackIcon Kind="SinaWeibo" VerticalAlignment="Center" Foreground="White"/>
                </Button>
            </StackPanel>
        </StackPanel>
        <Button BorderBrush="{x:Null}" Background="{x:Null}" HorizontalAlignment="Right" VerticalAlignment="Top"
                Click="CloseWindow_Click">
            <materialDesign:PackIcon Kind="Close"/>
        </Button>
        <StackPanel Margin="310,50,0,50">
            <TextBlock Text="欢迎回来" Foreground="White" HorizontalAlignment="Center" FontSize="48" FontFamily="Champagne &amp; Limousines" FontWeight="Bold"/>
            <TextBlock Text="使不可能成为可能，使可能变得简单而优雅" Foreground="White" HorizontalAlignment="Center" Width="280" FontSize="24" FontFamily="Champagne &amp; Limousines" TextWrapping="Wrap" TextAlignment="Center" Margin="0,50,0,0"/>
            <TextBlock Text="https://dotnet9.com" Foreground="White" FontSize="18" FontFamily="Champagne &amp; Limousines" TextWrapping="Wrap" TextAlignment="Right" Margin="10"/>
        </StackPanel>
    </Grid>
</Window>

下面是后台代码：文件【MainWindow.xaml.cs】，关闭窗体、窗体移动等事件处理。

using System.Windows;
using System.Windows.Input;

namespace Login
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }

        private void CloseWindow_Click(object sender, RoutedEventArgs e)
        {
            this.Close();
        }

        private void MoveWindow_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            DragMove();
        }
    }
}
