.net core Winform 添加DI和读取配置、添加log

首先新建配置类

 public class CaptureOption
    {
 
        /// <summary>
        /// 是否自启
        /// </summary>
        public bool AutoStart { get; set; }
 
        /// <summary>
        /// 是否设置为壁纸
        /// </summary>
        public bool SetWallpaper { get; set; } = true;
  }

然后添加appsettings.json, 复制到输出目录选择 如果较新则复制

"CaptureOptions": {
        "AutoStart": false,
        "SetWallpaper": true
}

nuget 安装

Microsoft.Extensions.Configuration.Json

Microsoft.Extensions.DependencyInjection

Microsoft.Extensions.Options.ConfigurationExtensions

Microsoft.Extensions.Logging

Microsoft.Extensions.Logging.Debug

如果需要httpclientFactory则还需要安装 Microsoft.Extensions.Http

最后是main函数里配置

        static void Main()
        {
            Application.SetHighDpiMode(HighDpiMode.SystemAware);
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
 
            //添加配置读取
            var config = new ConfigurationBuilder().AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                .Build();
 
            //添加DI
            var services = new ServiceCollection();
            services.AddOptions();
            services.AddSingleton(config);
            services.Configure<CaptureOption>(config.GetSection("CaptureOptions"));
            services.AddLogging(builder =>
            {
                builder.AddDebug(); //添加日志输出

            }); 

            //添加主窗体为单例 
            services.AddSingleton(typeof(MainForm)); 

            var serviceProvider = services.BuildServiceProvider(); 
            Application.Run(services.BuildServiceProvider().GetRequiredService<MainForm>()); }

最后通过注入IOptionsSnapshot 能监听到appsettings.json的变化
