自定义Net Configuration 类 - 继承ConfigurationSection

配置文件在应用程序开发中发挥及其重要的作用，使用配置文件可以动态改变应用程序的程序处理逻辑。
在.net framework 2.0平台中更是使得处理配置文件更加方便、灵活。同时微软也提供了自定义配置文件处理类的功能，

实现自定义配置类主要通过继承ConfigurationSection或者实现IConfigurationSectionHandler
这篇文章介绍的方法是继承 ConfigurationSection的 MySampleConfigurationSection

using System;
using System.Collections.Generic;
using System.Text;

using System.Configuration;

namespace ConfigSample

测试的app.config 文件

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="mySampleConfigurationSectionGroup">
      <section name="mySampleConfigurationSection" type="ConfigSample.MySampleConfigurationSection,ConfigSample,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null" allowLocation="true" allowDefinition="Everywhere"/>
    </sectionGroup>
  </configSections>
  <mySampleConfigurationSectionGroup>
    <mySampleConfigurationSection myAttribute1="MyAttribute1 value">
      <myChildSection myChildAttribute1="MyChildAttribute1 value" myChildAttribute2="MyChildAttribute2 value" />
    </mySampleConfigurationSection>
  </mySampleConfigurationSectionGroup>
</configuration>

测试该Configuration代码

    // get sample configuration section
            MySampleConfigurationSection myConfigSection = (MySampleConfigurationSection)ConfigurationManager.GetSection("mySampleConfigurationSectionGroup/mySampleConfigurationSection");
            if (myConfigSection != null)

特别注意的是configure在SectionGroup的调用路径

ConfigurationManager.GetSection("mySampleConfigurationSectionGroup/mySampleConfigurationSection")
