C#中XML操作简析1

用到了一个XML文件，只是很简单的应用，写下来备查。

XML文件

文件名：Setting.xml

<?xml version="1.0" encoding="utf-8"?>
<SettingRoot>
  <ServerIP>127.0.0.1</ServerIP>
  <ServerPort>5003</ServerPort>
  <ServiceType>1</ServiceType>
  <ServiceMode>2</ServiceMode>
  <ClientLoginInterval>3</ClientLoginInterval>
  <ServerRefreshInterval>30</ServerRefreshInterval>
</SettingRoot>

读取内容：

使用XMLDocument

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(“Setting.xml”);

XmlNode xnIP = xmlDoc.SelectSingleNode("SettingRoot/ServerIP");

String strIP=xnIP.InnerText;  //strIP=”127.0.0.1”

更改保存：

XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(“Setting.xml”);

XmlNode xnIP = xmlDoc.SelectSingleNode("SettingRoot/ServerIP");

xnIP.InnerText=”192.168.0.1”;

xmlDoc.Save(“Setting.xml”);

搞定，就这么多！！
