用属性(Attribution)来标记了对应的属性(Property)
如[ConfigurationProperty( " name " )]
下面结合App.config来看

App.config
1 <? xml version="1.0" encoding="utf-8"  ?>
2 < configuration >
3    < configSections >
4      < section  name ="EditorSettings"  type ="ConsoleApplication1.EditorFontData, ConsoleApplication1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null"   />
5    </ configSections >
6    < EditorSettings  name ="Verdana"  size ="24"  style ="2"   />
7 </ configuration >

可见，每个属性(Attribute)都对应着XML节点的属性


与2.0不同的是，4.1中好像没法用用Enterprise Library Configuration配置应用程序
以下是配置的详细步骤：
先建立一个项目，
然后建立自定义配置数据类，
在App.config或Web.config中添加节点<configSections>
在<configSections>节点下添加你自定义的节点的信息如：

   < configSections >
     < section  name ="EditorSettings"  type ="ConsoleApplication1.EditorFontData, ConsoleApplication1, Version=1.1.0.0, Culture=neutral, PublicKeyToken=null"   />
   </ configSections >

然后添加你自定义的节点
在工程中添加引用System.Configureation，如图所示：


读的代码：

EditorFontData configData  =  ConfigurationManager.GetSection( " EditorSettings " )  as  EditorFontData;

写的代码：

//  Write the new configuration data to the XML file
Configuration config  =  ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.Sections.Remove( " EditorSettings " );
config.Sections.Add( " EditorSettings " , configData);
config.Save();

清除缓存的代码：

ConfigurationManager.RefreshSection( " EditorSettings " );
