今天终于花了点时间了解一下IConfigurationSectionHandler 接口的用法 ,引以入门.
首先建立一 RobsunConfigSectionHandler 专案,代码如下 :

namespace RobsunConfigSectionHandler
{    public class RobsunParaSectionHandler:IConfigurationSectionHandler
    {        #region IConfigurationSectionHandler 成員        public object Create(object parent, object configContext, XmlNode section)
        {
            RobsunPara para = new RobsunPara();            foreach (XmlNode xn in section.ChildNodes)
            {                switch (xn.Name)
                {                    case "path":
                        para.Path = xn.SelectSingleNode("@value").InnerText;                        break;                    case "companyName":
                        para.CompanyName = xn.SelectSingleNode("@value").InnerText;                        break;                    case "isPrivate":
                        para.IsPrivate = bool.Parse(xn.SelectSingleNode("@attribute").InnerText);                        break;
                }
            }            return para;
        }        #endregion
    }
}

RobsunParaSectionHandler类实现 IConfigurationSectionHandler 接口.

RobsunPara类(实际就是参数类)的代码如下:

    public class RobsunPara
    {        #region code        private string _path = "";        private string _companyName = "";        private bool _isPrivate = false;        public string Path
        {            get { return _path; }            set { _path = value; }
        }        public string CompanyName
        {            get { return _companyName; }            set { _companyName = value; }
        }        public bool IsPrivate
        {            get { return _isPrivate; }            set { _isPrivate = value; }
        }        #endregion
    }

ConfigurationHander类的创建工作已完成,次handler的工作必须配合如下配置文件的格式(其实的配置文件依赖handler).这里是web.config(三种配置文件任一,web.config,App.config,machine.config ,前两种会覆盖machine.config,当然这里是没法子在App.config配置了 ~Q~ )

<sectionGroup name="robsunGroup"><section name="robsunSection" type="RobsunConfigSectionHandler.RobsunParaSectionHandler,RobsunConfigSectionHandler"/><path value="NONE"/><companyName value="Robsun"/><isPrivate attribute="true"/>
    ...

准备代码都已完成.剩下的就是拿来用了....
这里为了简单起见,就直接在page_load里实现了:

    Page_Load(= ConfigurationManager.GetSection()  + para.CompanyName +  + para.Path + Environment.NewLine +  + para.IsPrivate.ToString() +
