读取配置文件

1.读取JSON配置文件

 /// <summary>
        /// 获取配置文件
        /// </summary>
        /// <returns></returns>
        public static List<T> GetConfigs<T>(string configName)
        {
            var filePath = string.Concat(AppContext.BaseDirectory, configName);
            if (File.Exists(filePath))
            {
                string jsonContent = File.ReadAllText(filePath);
                var config = Newtonsoft.Json.JsonConvert.DeserializeObject<List<T>>(jsonContent);
                if (config != null)
                    return config;
            }
            return new List<T>();
        }

2.读取AppConfig配置

 /// <summary>
        /// 得到指定节点的配置值
        /// </summary>
        /// <param name="keyName"></param>
        /// <returns></returns>q
        public static string GetAppConfigString(string keyName)
        {
            return ConfigurationManager.AppSettings[keyName];
        }

        public static string GetConnectionString(string name)
        {

            var key = ConfigurationManager.ConnectionStrings[name];
            return key != null
                ? key.ConnectionString
                : ConfigurationManager.ConnectionStrings[0].ConnectionString;
        }
