C# WPF 一个设计界面
C# WPF 一个设计界面
今天正月初三，大家在家呆着挺好，不要忘了自我充电。
武汉人民加油，今早又有噩耗，24号（8号）一路走好。

1. 本文背景
一个不错的界面设计
2. 代码实现
使用 .NET Framework 4.8 创建名为 “Dashboard1” 的WPF模板项目，添加3个Nuget库：MaterialDesignThemes.3.1.0-ci981、MaterialDesignColors.1.2.3-ci981和ModernUICharts.WPF.Beta.0.9.1，ModernUICharts 库用于绘制统计图，此库没有 .NET CORE 版本，所以项目是创建的 .NET Framework 版本。
解决方案主要文件目录组织结构：
- Dashboard1
- App.xaml
- MainWindow.xaml
- MainWindow.xaml.cs
2.1 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.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 演示窗体
文件【MainWindow.xaml】，布局代码、统计图MVVM绑定代码都在此文件中，源码如下：

窗口布局代码也不多，就是布局和数据绑定，下面是后台代码：文件【MainWindow.xaml.cs】，ViewModel绑定、关闭窗体、窗体移动等事件处理，因为是演示事例，所以写的简单。
using System.Collections.Generic;
using System.Windows;
using System.Windows.Input;
namespace Dashboard1
{
/// <summary>
/// MainWindow.xaml的逻辑交互
/// </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 = "电量消耗";
Percent = CalcularPercent();
}
private int CalcularPercent()
{
return 47; //消费百分比的计算
}
}
}
