C#读写XML文件

使用Configuration读取xml文件

XML文件格式

<appSettings> <add key="WebPath" value="http://www.baidu.com"/> </appSettings>

读取：

System.Configuration.ConfigurationManager.AppSettings["WebPath"];

xml文件

<?xml version="1.0" encoding="utf-8"?> <widget id="io.cordova.hellocordova" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0"> <content src="index.html" /> <feature name="echo"> <param name="win" value="EchoCommand" /> </feature> <feature name="File"> <param name="win" value="File" /> </feature> <feature name="MacAddress"> <param name="win" value="MacAddress" /> </feature> <feature name="devices"> <param name="win" value="Device" /> </feature> <access origin="*"> <Root xmlns=""> <Child1>1</Child1> <Child2>2</Child2> <Child3>3</Child3> <Child4>4</Child4> <Child5>5</Child5> </Root> </access> <allow-intent href="http://*/*" /> <allow-intent href="https://*/*" /> <allow-intent href="tel:*" /> <allow-intent href="sms:*" /> <allow-intent href="mailto:*" /> <allow-intent href="geo:*" /> </widget>
