Asp.Net Core 配置文件

  public class ConfigurationManager
    {
        public readonly static IConfiguration Configuration;
        static ConfigurationManager()
        {
            Configuration = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json", optional: true).Build();
        }

    }

二 控制器内读取方式

   public class HomeController : Controller
    {

        public IActionResult Index()
        {
                     //读取
            string str=ConfigurationManager.Configuration["Logging:LogLevel:Default"];
            return View();
        }
    }
