關於自訂配置節，在此不多說，對於自己讀取節點，然後自己靜態緩衝的（以前寫過此類文章），也不多說

只說一下在使用還原序列化時，節點標記與類名的注意問題（只在類上加序列化標記，各屬性為預設序列）

問題出現：無法完成還原序列化，不報錯誤，但配置沒有讀出

原因：由於個人代碼習慣，類的第一個字母總是大寫，而XML標記第一個字母小寫

註：在使用還原序列化時，類名與標記名必須一致（區分大小寫），就我習慣來說，就是有一方必須不規範

當然，如果你每個屬性都加上序列化標記，指定XML元素名稱，則不在此列

程式碼範例：

1、設定檔範例，這是配置靜態頁模板的

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
  <section name="templateConfiguration" type="JournalUpdateService.Config.TemplateConfigurationHandle, WindowsApplication1" />
</configSections>
<templateConfiguration>
  <Templates>
   <Template pageName="Item.aspx">
    <head>E:/Projects/CNKIECP/Center/Web/WindowsApplication1/bin/Debug/Template/ITEM/Header.txt</head>
    <body>E:/Projects/CNKIECP/Center/Web/WindowsApplication1/bin/Debug/Template/ITEM/Body.txt</body>
    <bodyHeader>E:/Projects/CNKIECP/Center/Web/WindowsApplication1/bin/Debug/Template/ITEM/BodyHeader.txt</bodyHeader>
    <bodyContext>E:/Projects/CNKIECP/Center/Web/WindowsApplication1/bin/Debug/Template/ITEM/ItemBody.txt</bodyContext>
    <bodyFooter>E:/Projects/CNKIECP/Center/Web/WindowsApplication1/bin/Debug/Template/ITEM/BodyFooter.txt</bodyFooter>
   </Template>
  </Templates>
</templateConfiguration>
<appSettings>

</appSettings>
</configuration>

2、Handle 配置節點處理函數，實現IConfigurationSectionHandler 介面

using System;
using System.Configuration;
using System.Xml;
using System.Xml.Serialization;
using System.Xml.XPath;

namespace JournalUpdateService.Config
{
/// <summary>
/// TemplateConfigurationHandle 的摘要說明。
/// </summary>
public class TemplateConfigurationHandle : IConfigurationSectionHandler
{
  public TemplateConfigurationHandle()
  {
  }

  public object Create(object parent, object configContext, System.Xml.XmlNode section)
  {
   XmlSerializer ser = new XmlSerializer(typeof(TemplateConfiguration));

   // Return the Deserialized object from the Web.config XML
   return ser.Deserialize(new XmlNodeReader(section));
  }
}
}

3、Configration 自訂配置的根節點

using System;
using System.Collections;
using System.Xml.Serialization;

namespace JournalUpdateService.Config
{
/// <summary>
/// TemplateConfiguration 的摘要說明。
/// </summary>
///<configuration>
/// <configSections>
///   <section name="templateConfiguration"
///               type="JournalUpdateService.Config.TemplateConfigurationHandle, WindowsApplication1" />
///  </configSections>
///
///  <templateConfiguration>
///   <templates>
///    <template pageName="">
///     <head fileRef="" />
///     <body fileRef="" />
///     <bodyHeader fileRef="" />
///     <bodyContext fileRef="" />
///     <bodyFooter fileRef="" />
///    </template>
///   </templates>
///  </templateConfiguration>
/// </configuration>
[Serializable()]
[XmlRoot("templateConfiguration")]
public class TemplateConfiguration
{
  private TemplateCollection _templates;
  public TemplateConfiguration()
  {
   //
   // TODO: 在此處添加建構函式邏輯
   //
  }

  public TemplateCollection Templates
  {
   get
   {
    return _templates;
   }
   set
   {
    _templates = value;
   }
  }
}
}

4、Collection配置集合，實現CollectionBase介面

using System;
using System.Collections;

namespace JournalUpdateService.Config
{
/// <summary>
/// TemplateColection 的摘要說明。
/// </summary>
/// <template pageName="">
///  <head fileRef="" />
///  <body fileRef="" />
///  <bodyHeader fileRef="" />
///  <bodyContext fileRef="" />
///  <bodyFooter fileRef="" />
/// </template>
[Serializable()]
public class TemplateCollection : CollectionBase
{
  public TemplateCollection()
  {
   //
   // TODO: 在此處添加建構函式邏輯
   //
  }
  public virtual void Add(Template r)
  {
   this.InnerList.Add(r);
  }

  public Template this[int index]
  {
   get
   {
    return (Template) this.InnerList[index];
   }
   set
   {
    this.InnerList[index] = value;
   }
  }
}
}

5、配置實體

using System;
using System.Xml.Serialization;

namespace JournalUpdateService.Config
{
/// <summary>
/// Template 的摘要說明。
/// </summary>
[Serializable()]
public class Template
{
  private string _pageName;
  private string _head;
  private string _body;
  private string _bodyHeader;
  private string _bodyContext;
  private string _bodyFooter;

  public Template()
  {
  }

  [XmlAttribute]          //序列化為屬性
  public string pageName
  {
   get
   {
    return _pageName;
   }
   set
   {
    _pageName = value;
   }
  }

  public string head
  {
   get
   {
    return _head;
   }
   set
   {
    _head = value;
   }
  }

  public string body
  {
   get
   {
    return _body;
   }
   set
   {
    _body = value;
   }
  }

  public string bodyHeader
  {
   get
   {
    return _bodyHeader;
   }
   set
   {
    _bodyHeader = value;
   }
  }

  public string bodyContext
  {
   get
   {
    return _bodyContext;
   }
   set
   {
    _bodyContext = value;
   }
  }

  public string bodyFooter
  {
   get
   {
    return _bodyFooter;
   }
   set
   {
    _bodyFooter = value;
   }
  }
}
}
