1. 本文背景

继续 MaterialDesignThemes 开源控件库学习,本文简单使用输入控件的水印附加属性:materialDesign:HintAssist.Hint。

登录界面

操作动画

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"
             xmlns:local="clr-namespace:Login"
             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 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="登录" Height="500" Width="350" 
        ResizeMode="NoResize" 
        WindowStartupLocation="CenterScreen" 
        WindowStyle="None" 
        MouseLeftButtonDown="MoveWindow_MouseLeftButtonDown"
        FontFamily="Segoe UI Emoji">
    <Grid>

        <Rectangle Height="280" VerticalAlignment="Top">
            <Rectangle.Fill>
                <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                    <GradientStop Color="#FF2281D1"/>
                    <GradientStop Color="#FF34268A" Offset="1"/>
                    <GradientStop Color="#FF33288B" Offset="0.546"/>
                </LinearGradientBrush>
            </Rectangle.Fill>
        </Rectangle>

        <Rectangle Width="280" Height="240" VerticalAlignment="Bottom" Margin="0,80" RadiusY="10" RadiusX="10" Fill="White">
            <Rectangle.Effect>
                <DropShadowEffect BlurRadius="15" Direction="0" RenderingBias="Quality" ShadowDepth="1" Color="#FFBBBBBB"/>
            </Rectangle.Effect>
        </Rectangle>
        <Grid VerticalAlignment="Bottom" Margin="35,80" Height="240">
            <Label Content="登录" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="5" Foreground="Gray" FontSize="18"/>
            <StackPanel VerticalAlignment="Center" Margin="15">
                <TextBox Margin="0,10" materialDesign:HintAssist.Hint="账号" Style="{StaticResource MaterialDesignFloatingHintTextBox}" FontFamily="Champagne &amp; Limousines" FontSize="18"/>
                <PasswordBox Margin="0,10" materialDesign:HintAssist.Hint="密码" Style="{StaticResource MaterialDesignFloatingHintPasswordBox}" FontFamily="Champagne &amp; Limousines" FontSize="18"/>
            </StackPanel>
        </Grid>
        <Button Width="150" HorizontalAlignment="Center" VerticalAlignment="Bottom" Margin="0,65" Content="LOGIN"/>
        <TextBlock Text="忘记密码?" HorizontalAlignment="Center" VerticalAlignment="Bottom" Margin="30" Foreground="Gray" Cursor="Hand"/>
        <Button HorizontalAlignment="Right" VerticalAlignment="Top" Background="{x:Null}" BorderBrush="{x:Null}" Click="Close_Click">
            <materialDesign:PackIcon Kind="Close"/>
        </Button>
        <Image Source="https://img.dotnet9.com/logo-foot.png" Width="100" Height="100" VerticalAlignment="Top" Margin="30"/>
    </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 MoveWindow_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            DragMove();
        }

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