配置文件内容如下：
< configuration >
< configSections >
< section name ="mySection" type ="System.Configuration.NameValueSectionHandler"/>
< section name ="mySingleTagSection" type ="System.Configuration.SingleTagSectionHandler"/>
< section name ="myDictionarySection" type ="System.Configuration.DictionarySectionHandler"/>
< sectionGroup name ="mySections">
< section name ="mySection1" type ="System.Configuration.NameValueSectionHandler"/>
< section name ="mySection2" type ="System.Configuration.NameValueSectionHandler"/> < mySection >
< add key ="key1" value ="value1" />
< add key ="key2" value ="value2" /> < mySingleTagSection setting1 ="value1" setting2 ="value2" setting3 ="value3" />
< myDictionarySection >
< add key ="DictionarySectionKey1" value ="DictionarySectionValue1"/>
< add key ="DictionarySectionKey2" value ="DictionarySectionValue2"/>
< add key ="DictionarySectionKey3" value ="DictionarySectionValue3"/> < mySections >
< mySection1 >
< add key ="mySection1_key1" value ="mySection1_value1" />
< add key ="mySection1_key2" value ="mySection1_value2" /> < mySection2 >
< add key ="mySection2_key1" value ="mySection2_value1" />
< add key ="mySection2_key2" value ="mySection2_value2" /> < appSettings >
< add key ="appkey1" value ="appvalue1" />
< add key ="appkey2" value ="appvalue2" />

{
