C# WPF 一般登入介面

本文只是簡單的登入介面佈局，沒有太重要的功能效果。

1. 實作效果

2. 業務場景

常規業務

3. 編碼實作

3.1 新增 NuGet 套件

使用 .NET Core 3.1 建立名為 "Login" 的 WPF 解決方案，新增 1 個 NuGet 套件：MaterialDesignThemes。

3.2 專案結構

2 個檔案變動：

1. App.xaml：新增 MD 控制項樣式
2. MainWindow.xaml：主視窗實作效果

3.2.1 App.xaml 引入 MD 控制項樣式

關鍵樣式引用程式碼

<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 主視窗 MainWindow.xaml

全部程式碼，登入視窗佈局
