.net1.1中如果需要靈活的操作和讀寫(xiě)配置文件并不是十分方便，一般都會(huì)在項(xiàng)目中封裝一個(gè)配置文件管理類來(lái)進(jìn)行讀寫(xiě)操作。而在.net2.0中使用
ConfigurationManager
和
WebConfigurationManager
類可以很好的管理配置文件，ConfigurationManager類在System.Configuration中，WebConfigurationManager在System.Web.Configuration中。根據(jù)MSDN的解釋，對(duì)于 Web 應(yīng)用程序配置，建議使用
System.Web.Configuration.WebConfigurationManager
類，而不要使用
System.Configuration.ConfigurationManager
類。

下面我給出一個(gè)簡(jiǎn)單的例子說(shuō)明如何使用 WebConfigurationManager 操作配置文件：
???????
//
打開(kāi)配置文件
????????Configuration?config?
=
?WebConfigurationManager.OpenWebConfiguration(
"
~
"
);
????????
//
獲取appSettings節(jié)點(diǎn)
????????AppSettingsSection?appSection?
=
?(AppSettingsSection)config.GetSection(
"
appSettings
"
);
????????
//
在appSettings節(jié)點(diǎn)中添加元素
????????appSection.Settings.Add(
"
addkey1
"
,?
"
key1's?value
"
);
????????appSection.Settings.Add(
"
addkey2
"
,?
"
key2's?value
"
);
????????config.Save();
<
appSettings
>
??
<
add?key
=
"
addkey1
"
?value
=
"
key1's?value
"
?
/>
??
<
add?key
=
"
addkey2
"
?value
=
"
key2's?value
"
?
/>
</
appSettings
>
修改和刪除節(jié)點(diǎn)或?qū)傩砸卜浅７奖悖?
???????
//
打開(kāi)配置文件
????????Configuration?config?
=
?WebConfigurationManager.OpenWebConfiguration(
"
~
"
);
????????
//
獲取appSettings節(jié)點(diǎn)
????????AppSettingsSection?appSection?
=
?(AppSettingsSection)config.GetSection(
"
appSettings
"
);
????????
//
刪除appSettings節(jié)點(diǎn)中的元素
????????appSection.Settings.Remove(
"
addkey1
"
);
????????
//
修改appSettings節(jié)點(diǎn)中的元素
????????appSection.Settings[
"
addkey2
"
].Value?
=
?
"
Modify?key2's?value
"
;
????????config.Save();
配置文件：
<
appSettings

???
<
add?key
=
"
addkey2
"
?value
=
"
Modify?key2's?value
"
?

運(yùn)行代碼之后可以看見(jiàn)配置文件中的改變：
