C# XML 反序列化解析

自己用。记录一下！

用于配置文件的解析，可以用来设置配置。不用修改程序里参数。

用微软的XML 解析器来解析的。

1. Xml文件

文件名称：TestConfig.xml

<?xml version="1.0"?>
<Config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <PowerLine>
    <Version>1.01</Version>
    <FieldNum>10</FieldNum>
    <Fields>
      <Field name="STARTID">起始ID</Field>
      <Field name="FNODE">起点</Field>
      <Field name="TNODE">终点</Field>
      <Field name="POWERID">线路ID</Field>
    </Fields>
  </PowerLine>
</Config>

2.  对类的结构定义

文件名称：ParaseConfig.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using System.Xml;
using System.Xml.Serialization;
//
namespace PowerCongfig
{  

    // 名称和对应值
    public class FieldNode
    {
        [XmlAttribute("name")]
        public string name { get; set; }
        [XmlText]
        public string Value{ get; set; }
    }

    // 名称和对应值
    public class FieldsNode
    {
        [XmlElement("Field")]
        public List<FieldNode> oFieldNode { get; set; }
    }

    //
    public class PowerLine
    {
        [XmlElement("Version")]  // 版本
        public double dVersion;

        [XmlElement("FieldNum")] // 属性字段个数
        public int CountNode { get; set; }

        [XmlElement("Fields")]
        public FieldsNode oFieldsNode { get; set; }
    }

    [XmlRoot("Config")]
    public class TestRoot
    {
        [XmlElement("PowerLine")]
        public PowerLine oPowerLine { get; set; }
    }
}

3. 反序列化解析Xml

文件名称：

Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace PowerCongfig
{
    class Program
    {
        static void Main(string[] args)
        {
            // BuildXMlCofig();
            ParaseXMLConfig();
        }

        // 用来生成Xml文件
        private static void BuildXMlCofig()
        {
            TestRoot oTestRoot = new TestRoot();
            oTestRoot.oPowerLine = new PowerLine();
            oTestRoot.oPowerLine.dVersion = 1.01;
            oTestRoot.oPowerLine.CountNode = 10;

            //

            FieldNode oFieldNode0 = new FieldNode();
            oFieldNode0.name="STARTID";
            oFieldNode0.Value="起始ID";

            FieldNode oFieldNode1 = new FieldNode();
            oFieldNode1.name="FNODE";
            oFieldNode1.Value="起点";
            FieldNode oFieldNode2 = new FieldNode();
            oFieldNode2.name="TNODE";
            oFieldNode2.Value="终点";
            FieldNode oFieldNode3 = new FieldNode();
            oFieldNode3.name="POWERID";
            oFieldNode3.Value="线路ID";
            //
            oTestRoot.oPowerLine.oFieldsNode = new FieldsNode();
            oTestRoot.oPowerLine.oFieldsNode.oFieldNode = new List<FieldNode>();
            oTestRoot.oPowerLine.oFieldsNode.oFieldNode.Add(oFieldNode0);
            oTestRoot.oPowerLine.oFieldsNode.oFieldNode.Add(oFieldNode1);
            oTestRoot.oPowerLine.oFieldsNode.oFieldNode.Add(oFieldNode2);
            oTestRoot.oPowerLine.oFieldsNode.oFieldNode.Add(oFieldNode3);           

            // 序列化
            // 保存文件名称
            string oFileName = "C:\\my_Test.xml";

            System.Xml.Serialization.XmlSerializer serializer = null;
            System.IO.StreamWriter writer = null;
            try
            {
                serializer = new System.Xml.Serialization.XmlSerializer(oTestRoot.GetType());
                FileStream fs = new FileStream(oFileName, FileMode.Create);
                serializer.Serialize(fs, oTestRoot);
            }
            catch (System.Exception ex)
            {
                string mes = ex.Message;

            }
            finally
            {
                if (writer != null)
                {
                    writer.Close();
                }
            }
        }

        // 解析Xml到类对象中。
        private static void ParaseXMLConfig()
        {
            TestRoot oTestRoot = new TestRoot();
            oTestRoot.oPowerLine = new PowerLine();
            oTestRoot.oPowerLine.oFieldsNode = new FieldsNode();
            oTestRoot.oPowerLine.oFieldsNode.oFieldNode = new List<FieldNode>();

            string oFileName = @"D:\zhangpengju\CodeTest\testcplus\TestConfig.xml";
            System.Xml.Serialization.XmlSerializer serializer = null;
            System.IO.StreamWriter writer = null;
            try
            {
                serializer = new System.Xml.Serialization.XmlSerializer(oTestRoot.GetType());
                FileStream fs = new FileStream(oFileName, FileMode.Open);
                oTestRoot = (TestRoot)serializer.Deserialize(fs);
            }
            catch (System.Exception ex)
            {
                string mes = ex.Message;

            }
            finally
            {
                if (writer != null)
                {
                    writer.Close();
                }
            }
            //
            Console.WriteLine("Version is {0}",oTestRoot.oPowerLine.dVersion);
            Console.ReadLine();
        }
    }
}

就这样。自己保存！
