    • 获取配置文件中configSections的配置信息‖
    configSections关联的类型在一
    个进程内只实例化一次，

    　　1、配置文件Web.config


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

    　　<configuration>

    　　 <configSections>

    　　　<section name="xinyulou" type="Config.ConfigurationHandler, Config" />

    　　 </configSections>

    　　                                                                             
    　　 <xinyulou>　

    　　　<add name="Region" value = "心雨楼" />

    　　　</xinyulou>

    　　                                                                             
    　　 <system.web>　

    　　　<compilation defaultLanguage="c#" debug="true" />

    　　　<customErrors mode="RemoteOnly" />

    　　　<authentication mode="Windows" />

    　　　<authorization>

    　　　 <allow users="*" /> <!-- <sectionGroup name="xinyulou"> 允许所有用户 -->

    　　　</authorization>

    　　　<trace enabled="false" requestLimit="10" pageOutput="false" traceMode="SortByTime" localOnly="true" />

    　　　<sessionState m
    7.0.0.1:42424" sqlConnec
    		ode="InProc" stateConnection
    tionString="data source=127.
    		String="tcpip=12
    0.0.1;Trusted_Connection=yes"
    　　　 cookieless="false" timeout="20" />

    　　　<globalization requestEncoding="utf-8" responseEncoding="utf-8" />

    　　 </system.web>

    　　                                                                             
    　　</configuration>


    　　2、两个重要的类


    　　using System;                                                    
    　　using System.Configuration;                        
    　　using System.Collections;                            
    　　using System.Xml;                                            

    　　namespace Config                                              
    　　{                                                                           
    　　 public class Configuration                        
    　　 {                                                                          
    　　　private Hashtable
    		m_MyRegionConfig = new Hasht
    		able();
    　　　public Hashtable MyRegionConfig              
    　　　{                                                                          
    　　　 get {return m_MyRegionConfig;}              

    　　　}                                                                          
    　　　public static Configuration Ge
    		tConfig()
    　　　{                                                                          
    　　　 return (Configuration) Config
    		urationSettings.GetConfig("xinyulou");
    　　　}                                                                          
    　　　internal void Load
    		ValuesFromConfigurationXml(X
    		mlNode node)
    　　　{                                                                          
    　　　                                                                           
    　　　 foreach (XmlNode child in nod
    		e.ChildNodes)
    　　　 {                                                                        
    　　　　m_MyRegionConfig
    tributes["value"].Value)
    		.Add(child.Attributes["name"
    ;　
    		].Value,child.At
    　　　 }                                                                        

    　　　}                                                                          

    　　 }                                                                          
    　　                                                                             
    　　 internal class Conf
    		igurationHandler : IConfigur
    		ationSectionHandler
    　　 {                                                                          

    　　　public virtual obj
    		ect Create(Object parent, Ob
    		ject context, XmlNode node)
    　　　{                                                                          
    　　　 Configuration config = new Co
    		nfiguration();
    　　　 config.LoadValuesFromConfigur
    		ationXml(node);
    　　　 return config;                                              
    　　　}                                                                          

    　　 }                                                                          
    　　}                                                                            

    　　3、示例在aspx中用！


    　　private void Page_Lo
    		ad(object sender, System.Eve
    		ntArgs e)
    　　　{                                                                          
    　　　 Response.Write(Co
    on"].ToString());
    		nfiguration.GetConfig().MyRe

    		gionConfig["Regi
    　　　}
