开挖 Domain - 前奏

WPF App

主机配置

Microsot.Extension.Hosting Nuget引用

一键启动（配置文件、依赖注入，日志）

// App.xaml.cs 中定义 IHost
private readonly IHost _host = Host.CreateDefaultBuilder().ConfigureAppConfiguration(c =>
{_ = c.SetBasePath(Environment.CurrentDirectory);//  配置文件// _ = c.AddJsonFile("appsettings.json");_ = c.AddIniFile("appsettings.ini");
}).ConfigureServices((c, s) =>
{// 后台服务 BackgroundService_ = s.AddHostedService<ApplicationHostService>();_ = s.AddHostedService<WorkerService>();// 视图_ = s.AddSingleton<MainWindow>();_ = s.AddSingleton<ViewModels.MainWindowViewModel>();_ = s.AddSingleton<ModuleForLogView>();_ = s.AddSingleton<ViewModels.ModuleForLogViewModel>();// 依赖注入_ = s.AddScoped<IMonkey, Monkey>();
}).ConfigureLogging((c, l) =>
{l.ClearProviders();// Logging 自带的仅能输出至控制台// NLog 扩展 记录到文件l.AddNLog();
}).Build();

构造函数注入，读取配置信息

更丰富的注入还需要 Autofac
配置文件支持 json，ini 等，使用_config[“A:B”]写法读取配置项
ini配置文件

private readonly IMonkey _monkeyService;
private readonly ILogger<ModuleForLogViewModel> _logger;
private readonly IConfiguration _config;
public ModuleForLogViewModel(IMonkey monkeyService, ILogger<ModuleForLogViewModel> logger, IConfiguration config)
{_monkeyService = monkeyService;_logger = logger;_config = config;// 读取配置var s = _config["项目:年份"];_logger.LogInformation(s);MessageBox.Show(_monkeyService.Act());
}
