应用Xml.Linq读xml文件详解编程语言

c#提供了System.Xml.Linq操作xml文件，非常方便，本文主要介绍如何应用System.Xml.Linq读取xml文件。

xml文本

<?xml version="1.0" encoding="UTF-8"?> 
<TestScript> 
    <default> 
        <id>5DC48A0B-11DC-4B40-A41E-F28AE4260538</id> 
        <name>SetNetworkAdapter</name> 
        <title>设置IP地址</title> 
        <desc></desc> 
    </default> 
    <channels> 
        <channel id="1" name="ap_agent"> 
            <open>127.0.0.1:4754</open> 
        </channel> 
    </channels> 
    <actions> 
        <action id="1" waitResponse="false" breakOnFail="false"> 
            <io>ap_agent</io> 
            <predelay>0</predelay> 
            <command>SetNetworkAdapter</command> 
            <repeat>0</repeat> 
            <postdelay>0</postdelay> 
            <params> 
                <param id="1" order="1" name="ip" title="ip地址" value="192.168.1.112" unit="" type="input" enable="true" limitUp="" limitDown="" hint=""/> 
                <param id="2" order="2" name="mask" title="子网掩码" value="255.255.255.0" unit="" type="input" enable="true" limitUp="" limitDown="" hint=""/> 
                <param id="3" order="3" name="gateway" title="网关" value="192.168.1.1" unit="" type="input" enable="true" limitUp="" limitDown="" hint=""/> 
            </params> 
        </action> 
    </actions> 
</TestScript> 
 

关键代码

public XmlAction LoadXml(string xmlFile) 
{ 
     XmlAction ret = new XmlAction(); 
     XElement xe = XElement.Load(xmlFile); 
     XElement eleAction = xe.Elements("actions").Elements("action").First(); 
     ret.Id = eleAction.Attribute("id").Value; 
     ret.WaitResponse = eleAction.Attribute("waitResponse").Value == "true"; 
     ret.BreakOnFail = eleAction.Attribute("breakOnFail").Value == "true"; 
     ret.Io = eleAction.Element("io").Value; 
     ret.Predelay = Convert.ToInt32(eleAction.Element("predelay").Value); 
     ret.Postdelay = Convert.ToInt32(eleAction.Element("postdelay").Value); 
     ret.Command = eleAction.Element("command").Value; 
     ret.Repeat = Convert.ToInt32(eleAction.Element("repeat").Value); 
     ret.Params = new List<Param>(); 
     foreach (XElement para in eleAction.Elements("params").Elements("param")) 
     { 
         Param p = new Param(); 
         ret.Params.Add(p); 
         p.Id = para.Attribute("id").Value; 
         p.Enable = para.Attribute("enable").Value == "true"; 
         p.Hint = para.Attribute("hint").Value; 
         p.LimitDown = para.Attribute("limitDown").Value; 
         p.LimitUp = para.Attribute("limitUp").Value; 
         p.Name = para.Attribute("name").Value; 
         p.Order = para.Attribute("order").Value; 
         p.Title = para.Attribute("title").Value; 
         p.Type = para.Attribute("type").Value; 
         p.Unit = para.Attribute("unit").Value; 
         p.Value = para.Attribute("value").Value; 
 
     } 
     return ret;
