代碼如下：
using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using System.Configuration;
using System.Xml;

namespace Beyondbit.Portal.ConfigService {
??? public class TopMenuConfigItem {
??????? public string Text;
??????? public string Value;
??????? public string Url;
??????? public string Description;
??? }

??? public class TopMenuConfig : IConfigurationSectionHandler {

??????? private IList<TopMenuConfigItem> topMenus;
??????? public IList<TopMenuConfigItem> TopMenus {
??????????? get {
??????????????? return topMenus;
??????????? }
??????? }

??????? public static TopMenuConfig Instance() {
??????????? return ConfigurationManager.GetSection("TopMenuConfig") as TopMenuConfig;
??????? }

??????? #region IConfigurationSectionHandler Members

??????? object IConfigurationSectionHandler.Create(object parent, object configContext, XmlNode section) {
??????????? XmlNode node = section;
??????????? topMenus = new List<TopMenuConfigItem>(node.ChildNodes.Count);

??????????? TopMenuConfigItem m = null;
??????????? foreach (XmlNode n in node.ChildNodes) {
??????????????? if (n.NodeType != XmlNodeType.Comment) {
??????????????????? m = new TopMenuConfigItem();
??????????????????? m.Description = n.Attributes["Description"].Value;
??????????????????? m.Text = n.Attributes["Text"].Value;
??????????????????? m.Url = n.Attributes["Url"].Value;
??????????????????? m.Value = n.Attributes["Value"].Value;
??????????????????? topMenus.Add(m);
