c# wpf 普通登錄界面

本文只是簡單的登錄界面布局，沒有太重要的功能效果。

1. 實現效果

2. 業務場景

常規業務

3. 編碼實現

3.1添加 nuget 庫

使用 .NET Core 3.1 创建名为 “Login” 的 WPF 解决方案，添加 1 个 NuGet 库：MaterialDesignThemes。

3.2工程結構

2 個文件變動：

1. app.xaml：添加 md 控制項樣式
2. mainwindow.xaml：主窗口實現效果

3.2.1 app.xaml 引入 md 控制項樣式

關鍵樣式引用代碼

<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.MergedDictionaries>
    <!--Primary-->
    <SolidColorBrush x:Key="PrimaryHueLightBrush" Color="#FFCDD2" />
    <SolidColorBrush x:Key="PrimaryHueLightForegroundBrush" Color="#FF333333" />
    <SolidColorBrush x:Key="PrimaryHueMidBrush" Color="#f44336" />
    <SolidColorBrush x:Key="PrimaryHueMidForegroundBrush" Color="#FFEEEEEE" />
    <SolidColorBrush x:Key="PrimaryHueDarkBrush" Color="#b71c1c" />
    <SolidColorBrush x:Key="PrimaryHueDarkForegroundBrush" Color="#FFFFFFFF" />
    <!--Accent-->
    <SolidColorBrush x:Key="SecondaryAccentBrush" Color="#ff1744" />
    <SolidColorBrush x:Key="SecondaryAccentForegroundBrush" Color="#FFFFFF" />
  </ResourceDictionary>
</Application.Resources>

3.2.2 主窗體 mainwindow.xaml

全部代碼，登錄窗口布局
