我有一个Web API项目，我有一个自定义JSON配置文件，我想在不使用microsoft.Extensions.Configuration的情况下将其合并到我的项目中。我对此很陌生，但我想避免使用任何.Net Core方法或路由。

以下是涉及的文件摘要：

Web.Config

<appSettings configSource="Config\base\appsettings.json"></appSettings>

appsettings.json

{
  "siteURL": "https://helloworld.com","TokenSecretKey": "justanothersecret","URI.Key": "anotherkey","ClientTokenSharedSecret": "somevalue","TwoFactorSessionExpirationInminutes": "43200","Email.From": "noreply@thatonesite.com","Email.Server": "192.168.1.1","Email.Server.User": "user","Email.Server.Password": "pword",}

WebApiConfig.cs

 public static class WebApiConfig
    {
        public static void Register(httpconfiguration config)
        {
            // Web API configuration and services
            var cors = new EnableCorsAttribute("*","*","*");
            config.EnableCors(cors);
            // Web API routes
            config.MapHttpAttributeRoutes();
            GlobalConfiguration.Configuration.Formatters.Add(new FormMultipartEncodedMediaTypeFormatter());

            config.Routes.MapHttpRoute(
                name: "DefaultApi",routeTemplate: "api/{controller}/{id}",defaults: new { id = RouteParameter.Optional }
            );
        }
    }

Global.asax.cs

public class WebApiapplication : system.web.HttpApplication
    {
        protected void Application_Start()
        {
            GlobalConfiguration.Configure(WebApiConfig.Register);
        }
    }

我的目标是将这些设置合并到项目中，并能够在项目中的任何地方使用。
