用屬性(Attribution)來(lái)標(biāo)記了對(duì)應(yīng)的屬性(Property)
如[ConfigurationProperty( " name " )]
下面結(jié)合App.config來(lái)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 >

可見，每個(gè)屬性(Attribute)都對(duì)應(yīng)著XML節(jié)點(diǎn)的屬性


與2.0不同的是，4.1中好像沒法用用Enterprise Library Configuration配置應(yīng)用程序
以下是配置的詳細(xì)步驟：
先建立一個(gè)項(xiàng)目，
然后建立自定義配置數(shù)據(jù)類，
在App.config或Web.config中添加節(jié)點(diǎn)<configSections>
在<configSections>節(jié)點(diǎn)下添加你自定義的節(jié)點(diǎn)的信息如：

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

然后添加你自定義的節(jié)點(diǎn)
在工程中添加引用System.Configureation，如圖所示：


讀的代碼：

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

寫的代碼：

// ?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();

清除緩存的代碼：

ConfigurationManager.RefreshSection( " EditorSettings " );
