少量代码设计一个登录界面 - .NET CORE(C#) WPF开发阅读导航
- 本文背景
- 代码实现
- 本文参考
- 源码
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。
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：
- LoginApp.xamlMainWindow.xamlMainWindow.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="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 & Limousines" FontSize="18"/>
<PasswordBox Margin="0 10" materialDesign:HintAssist.Hint="密码" Style="{StaticResource MaterialDesignFloatingHintPasswordBox}" FontFamily="Champagne & 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();
}
}
}
