C#配置文件Section节点处理总结

本文实例总结了c#配置文件section节点处理方法。分享给大家供大家参考。具体如下：

很多时候在项目开发中，我们都需要用配置文件来存储一些关于程序配置信息，这时候你可以选择ini或者app.config来存储，这里对此总结一下：

配置文件示例如下：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configsections>
    <sectiongroup name="module">
      <section name="appsettings" type="system.configuration.namevaluefilesectionhandler"/>
    </sectiongroup>
  </configsections>
  <module>
    <appsettings>
      <!--谷歌地图-->
      <add key="googlemap" value="1"/>
      <!--箱实时状态信息汇总-->
      <add key="cab_rt" value="1"/>
    </appsettings>
  </module>
</configuration>

操作代码如下：

using system;
using system.collections.specialized;
using system.configuration;

namespace consoleapplication38
{
    class program
    {
        static void main(string[] args)
        {
            try
            {
                sectiontoolv2 _sectionhelper = new sectiontoolv2("module/appsettings");
                console.writeline(_sectionhelper.getvalue("googlemap"));
                console.writeline(_sectionhelper.containkey("yanzhiwei"));
            }
            catch (exception ex)
            {
                console.writeline(ex.message);
            }
            finally
            {
                console.readline();
            }
        }
    }
    class sectiontoolv2
    {
        namevaluecollection modulsettings = null;
        /// <summary>
        ///构造函数
        /// </summary>
        /// <param name="sectionname">section名称</param>
        public sectiontoolv2(string sectionname)
        {
            modulsettings = configurationmanager.getsection(sectionname) as namevaluecollection;
        }
        /// <summary>
        /// 是否包含该section
        /// </summary>
        /// <returns></returns>
        public bool containsection()
        {
            return !(modulsettings == null);
        }
        /// <summary>
        /// section是否包含key
        /// </summary>
        /// <param name="key">键</param>
        /// <returns>值</returns>
        public bool containkey(string key)
        {
            if (containsection())
            {
                return !(modulsettings[key] == null);
            }
            return false;
        }
        /// <summary>
        /// 根据键获取值
        /// </summary>
        /// <param name="key">键</param>
        /// <returns>当不存在键的时候，返回string.empty</returns>
        public string getvalue(string key)
        {
            string _value = string.empty;
            if (containkey(key))
            {
                _value = modulsettings[key];
            }
            return _value;
        }
    }
}

测试效果如下：
