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;
