.Net Core自定义读取配置文件信息appsettings.Json

一、自定义读取配置文件信息appsettings.json

　　1.在startup类配置

1   　　　 public iconfiguration configuration { get; }
2         public iwebhostenvironment env { get; }
3         public startup(iconfiguration configuration, iwebhostenvironment env)
4         {
5             configuration = configuration;
6             env = env;
7         }

　　2.在startup类的configureservices配置

services.addsingleton(new appsettings(env.contentrootpath));

　　3.新建一个appsettings操作类

        static iconfiguration configuration { get; set; }

        static string contentpath { get; set; }

        public appsettings(string contentpath)
        {
            string path = "appsettings.json";

            configuration = new configurationbuilder()
               .setbasepath(contentpath)
               .add(new jsonconfigurationsource { path = path, optional = false, reloadonchange = true })
               .build();
        }
        /// <summary>
        /// 封装要操作的字符
        /// </summary>
        /// <param name="sections">节点配置</param>
        /// <returns></returns>
        public static string get(params string[] sections)
        {
            try
            {
                if (sections.any())
                {
                    return configuration[string.join(":", sections)];
                }
            }
            catch (exception) { }

            return "";
        }

　　4.如何使用

 string test = appsettings.get(new string[] { "test", "test1" });
