自定义配置节与XML反序列化并用

web.config

  </configSections>
  
  <system.web>

Menu.cs

using System.Xml.Serialization;
using System.Xml.Schema;

[XmlRootAttribute(ElementName = "menus", Namespace = "", IsNullable = false)]
public class Menus
{
    [XmlElementAttribute("menu", Form = XmlSchemaForm.Unqualified)]
    public Menu[] Items { get; set; }
}

[XmlTypeAttribute(AnonymousType = true)]
public class Menu
{
    [XmlAttributeAttribute("name")]
    public string Name { get; set; }

    [XmlArrayAttribute("children")]
    [XmlArrayItemAttribute("menu", typeof(Menu), Form = XmlSchemaForm.Unqualified, IsNullable = true)]
    public Menu[] Children { get; set; }

MenuSectionHandler.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Configuration;
using System.IO;
using System.Xml.Serialization;

namespace XmlSerializerPlus
{
    public class MenuSectionHandler : IConfigurationSectionHandler 
    {
        public object Create(object parent, object configContext, System.Xml.XmlNode section)
        {
            using (StringReader sr = new StringReader(section.OuterXml))
            { 
                var serializer = new XmlSerializer(typeof(Menus));
                return serializer.Deserialize(sr);
            }
        }
    }
}

测试代码：

protected void Page_Load(object sender, EventArgs e)
{
   Menus menus = ConfigurationManager.GetSection("menus") as Menus;
}
