如果使用了configSection节点，则configSection必须位于根节点的第0个。App.config中代码如下：

<?xml version="1.0" encoding="utf-8" ?>

<configuration>

  <configSections>

    <section name="CustomerSingleConfig" type="ConfiguraDemo.CustomerSingleConfig,ConfiguraDemo"/>

  </configSections>

  <startup>

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" />

  </startup>

  <CustomerSingleConfig PlatChName="监控平台系统" PlatEnName="Monitoring platform system"></CustomerSingleConfig>

</configuration>

using System;

using System.Collections.Generic;

using System.Configuration;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace ConfiguraDemo

{

    public class CustomerSingleConfig : ConfigurationSection

    {

        /// <summary>

        /// 获取配置信息

        /// </summary>

        /// <returns></returns>

        public static CustomerSingleConfig GetConfig()

        {

            return GetConfig("CustomerSingleConfig");

        }

        private static CustomerSingleConfig GetConfig(string sectionName)

        {

            try

            {

                CustomerSingleConfig section = (CustomerSingleConfig)ConfigurationManager.GetSection(sectionName);

                if (section == null)

                    throw new ConfigurationErrorsException("Section " + sectionName + " is not found.");

                return section;

            }

            catch (Exception ex)

            {

                throw new ConfigurationErrorsException("Section " + ex.Message);

            }

        }

        /// <summary>

        /// 平台中文名称

        /// </summary>

        [ConfigurationProperty("PlatChName", DefaultValue = "", IsRequired = true, IsKey = false)]

        public string PlatChineseName

        {

            get { return (string)this["PlatChName"]; }

            set { this["PlatChName"] = value; }

        }

        /// <summary>

        /// 平台英文名称

        /// </summary>

        [ConfigurationProperty("PlatEnName", DefaultValue = "", IsRequired = true, IsKey = false)]

        public string PlatEnglishName

        {

            get { return (string)this["PlatEnName"]; }

            set { this["PlatEnName"] = value; }

        }

    }

}

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace ConfiguraDemo

{

    class Program

    {

        static void Main(string[] args)

        {

            Console.WriteLine("---------------------单级配置节点测试-----------------");

            Console.WriteLine("PlatChName:" + CustomerSingleConfig.GetConfig().PlatChineseName);

            Console.WriteLine("PlatEnName:" + CustomerSingleConfig.GetConfig().PlatEnglishName);

            Console.ReadKey();

        }

    }

}

输出结果

---------------------单级配置节点测试-----------------

PlatChName:监控平台系统

PlatEnName:Monitoring platform system

继承ConfigurationSection需要添加System.Configuration引用
