简单键值对
web.config
<configSections>
<section name="users" type="System.Configuration.NameValueSectionHandler"/>
</configSections>
<users configSource="users.config"></users>users.config
<users> <add key="beijing" value="123"></add> <add key="tianjin" value="123"></add> </users>
c#
NameValueCollection users = System.Configuration.ConfigurationManager.GetSection("users") as NameValueCollection;
Response.Write(users.Keys[0]+"</br>"+users.Keys[1]);复杂类型
web.config
<configSections>
<section name="roles" type="EBuy.Chapter3.NTier.WebUI.RolesConfig, EBuy.Chapter3.NTier.WebUI"/>
</configSections>
<roles configSource="roles.config">
</roles>roles.config
<roles> <add username="beijing" password="123"></add> <add username="tianjin" password="123"></add> </roles>

public class RolesConfig : System.Configuration.IConfigurationSectionHandler

}
}c#
XmlNode roles= System.Configuration.ConfigurationManager.GetSection("roles") as XmlNode;
Response.Write(roles.ChildNodes [0].Attributes["username"].InnerText);还可以将配置节定义为一个实体
