系统默认的App.config文件，是XML格式的，可通过以下方式进行读取

class SystemConfig:ConfigurationSection
{

        [ConfigurationProperty("id")]
        public int Id
        {
            get { return (int)this["id"]; }
            set { this["id"] = value; }
        }

        [ConfigurationProperty ("aaServerName")]
        public string ServerName
        {
            get
            {
                return (string)this["aaServerName"];
            }
            set
            {
               this["aaServerName"] = value;
            }
        }
        [ConfigurationProperty ("DBName")]
        public string DBName
        {
            get
            {
                return (string)this["DBName"];
            }
            set
            {
                this["DBName"] = value;
            }
        }
        [ConfigurationProperty("Config1")]
        public string UserPwd
        {
            get
            {
                return (string)this["Config1"];
            }
            set
            {
                this["Config1"] = value;
            }
        }

        public string StationNo

                this["Config2"] = value;
            }
        }
        [ConfigurationProperty("Config3")]
        public string UserName
        {
            get
            {
                return (string)this["Config3"];

            }
            set
            {
                this["Config3"] = value;
            }
        }

    }
    public class SystemConfigOp//:ConfigurationSection

        }
        public int Id
        {
            get
            {
                return m_SysCon.Id;
            }
            set
            {
                m_SysCon.Id = value;
            }
        }

        public string ServerName
        {
            get
            {

            }
            set

        public string UserName

            }
            set

                m_SysCon.UserName = value;
            }
        }

}

这里要注意的时如果将来个类合并到一起，则不能在构造函数中限制唯一模式（Singleton)，因为好像Configuration 对象在SAVE时多次创建了该对象。
