应用Xml.Linq读xml文件

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;
