C# WPF 一個設計界面
今天正月初三，大家在家呆著挺好，不要忘了自我充電。
武漢人民加油，今早又有噩耗，24號（8號）一路走好。

1. 本文背景
一個不錯的界面設計
2. 代碼實現
使用 .NET Framework 4.8 創建名為 “Dashboard1” 的WPF模板項目，添加3個Nuget庫：MaterialDesignThemes.3.1.0-ci981、MaterialDesignColors.1.2.3-ci981和ModernUICharts.WPF.Beta.0.9.1，ModernUICharts 庫用於繪製統計圖，此庫沒有 .NET CORE 版本，所以項目是創建的 .NET Framework 版本。
解決方案主要文件目錄組織結構：
- Dashboard1
- App.xaml
- MainWindow.xaml
- MainWindow.xaml.cs
2.1 引入樣式
文件【App.xaml】，在 StartupUri 中設置啟動的視圖【MainWindow.xaml】，併在【Application.Resources】節點增加 MaterialDesignThemes庫的樣式文件：
<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>2.2 演示窗體
文件【MainWindow.xaml】，佈局代碼、統計圖MVVM綁定代碼都在此文件中，源碼如下：

</Window>視窗佈局代碼也不多，就是佈局和數據綁定，下麵是後臺代碼：文件【MainWindow.xaml.cs】，ViewModel綁定、關閉窗體、窗體移動等事件處理，因為是演示事例，所以寫的簡單。
using System.Collections.Generic;
using System.Windows;
using System.Windows.Input;
namespace Dashboard1
{
/// <summary>
/// MainWindow.xaml的邏輯交互
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
Consumo consumo = new Consumo();
DataContext = new ConsumoViewModel(consumo);
}
private void ButtonFechar_Click(object sender, RoutedEventArgs e)
{
Application.Current.Shutdown();
}
private void GridBarraTitle_MouseDown(object sender, MouseButtonEventArgs e)
{
DragMove();
}
}
internal class ConsumoViewModel
{
public List<Consumo> Consumo { get; private set; }
public ConsumoViewModel(Consumo consumo)
{
Consumo = new List<Consumo>();
Consumo.Add(consumo);
}
}
internal class Consumo
{
public string Title { get; private set; }
public int Percent { get; private set; }
public Consumo()
{
Title = "電量消耗";
Percent = CalcularPercent();
}
private int CalcularPercent()
{
return 47; //消費百分比的計算
}
}
