如何在xml中反序列化包含List的xmlelement

Question

我正在使用silverlight5和c＃来实现我的目标。 我有以下xml文件：

string xmlstring = 
<?xml version="1.0" encoding="utf-8" ?>
<parameter>
  <name>bands_amounts</name>
  <label>Bands Amounts</label>
  <unit></unit>
  <component>
    <type>List</type>
    <attributes>
      <type>Integer</type>
      <displayed>4</displayed>
      <add_remove>yes</add_remove> 
      <item>1 000 000</item>
      <item>5 000 000</item>
      <item>10 000 000</item>
      <item>20 000 000</item>
    </attributes>
    <attributes>
      <ccypair>XAUUSD</ccypair>
      <item>100</item>
      <item>500</item>
      <item>1000</item>
    </attributes>
  </component >
</parameter>

在反序列化时，我得到了3个班级。

 parameter.cs :
using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Runtime.Serialization.Json;
using System.Runtime;
using System.Xml.Serialization;
using System.Runtime.Serialization;
using System.IO;
using System.Collections.Generic;
using System.Diagnostics;


namespace Model.XML
{
   [XmlRoot("parameter")]
    public class parameter
    {
        public string name { get; set; }
        public string label { get; set; }

      [XmlElement("component")]
       public component component { get; set; }
    }
}

和

attribute.cs:
using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Runtime.Serialization.Json;
using System.Runtime;
using System.Xml.Serialization;
using System.Runtime.Serialization;
using System.IO;
using System.Collections.Generic;
using System.Diagnostics;
using System.Xml;


namespace Model.XML
{
    public class attributes
    {

        public string type { get; set; }    
        public string displayed { get; set; }
        public string add_remove { get; set; }
        public string ccypair { get; set; }
        public List<int> item { get; set; }

         public static void Main()
        {          
            string xmlstring = @"<?xml version='1.0' encoding='utf-8' ?> <parameter> <name>bands_amounts</name>   <label>Bands Amounts</label>   <unit>54</unit>  <component>    <type>List</type>    <attributes>      <type>Integer</type>     <displayed>4</displayed>    <add_remove>yes</add_remove>       <item>1 000 000</item>       <item>5 000 000</item>       <item>10 000 000</item>       <item>20 000 000</item>   </attributes>    <attributes>   <ccypair>XAUUSD</ccypair> <item>100</item> <item>500</item> <item>1000</item> </attributes>  </component > </parameter>";
            XmlSerializer serializer = new XmlSerializer(typeof(parameter));
            XmlReader reader = XmlReader.Create(new StringReader(xmlstring));
            var Object1 = (parameter)serializer.Deserialize(reader);
            foreach (var attrib in Object1.component.attribut)
            {
                Debug.WriteLine(attrib.type);
                Debug.WriteLine(attrib.item);

            }
        }  
    }
}

第三个：

component.cs
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Runtime.Serialization.Json;
using System.Runtime;
using System.Xml.Serialization;
using System.Runtime.Serialization;
using System.IO;
using System.Collections.Generic;
using System.Diagnostics;
using System.Xml;

namespace Model.XML
{
    public class component
    {

        [XmlElement("attributes")]
        public List<attributes> attribut { get; set; }

    /*    public static void Main()
        {
            string xmlstring = @"<?xml version='1.0' encoding='utf-8' ?> <parameter> <name>bands_amounts</name>   <label>Bands Amounts</label>   <unit>54</unit>  <component>    <type>List</type>    <attributes>      <type>Integer</type>     <displayed>4</displayed>    <add_remove>yes</add_remove>       <item>1 000 000</item>       <item>5 000 000</item>       <item>10 000 000</item>       <item>20 000 000</item>   </attributes>    <attributes>   <ccypair>XAUUSD</ccypair> <item>100</item> <item>500</item> <item>1000</item> </attributes>  </component > </parameter>";

            XmlSerializer deserializer = new XmlSerializer(typeof(parameter));          
            XmlReader reader = XmlReader.Create(new StringReader(xmlstring));

            var Object1 = (parameter)deserializer.Deserialize(reader);
            foreach (var attrib in Object1.component.attribut)
            {
                Debug.WriteLine(attrib.item);
              //  Debug.WriteLine(Object1.name);

            }
        }   */
    }
}

我的问题是当我尝试调试Debug.WriteLine(attrib.item);时，我无法在调试时看到“1 000 000”和“5 000 000”和“10 000 000” Debug.WriteLine(attrib.item); 在属性类中，“ccypair”在执行Debug.WriteLine（attrib.ccypair）时显示为null; （可能是因为这个xml的结构包含两个<attributes>..</attributes> <attributes>..</attributes> ）。 怎么弄他们？ 因为我的下一步是使用它们显示GUI，所以我需要它们的值。 有人可以请我，因为我是一个初学者。

我是否需要做以下事情：

 [XmlArray("component"), XmlArrayItem("attributes", typeof(attributes))]
        public List<attributes> component
        {
            get { return (_attributes); }
            set { _attributes = value; }
        }
        private List<attributes> _attributes = new List<attributes>();

因为这个包含“1 000 000”，“5 000 000”等的“项目”在“属性”内？ 请解释我，我是初学者

使用下面的代码，您可以序列化和反序列化您的对象，即使您可以存储您的xml

SerializeObject(objDividendList, filename);

objDividendList = DeSerializeObject>（filename）;

public void SerializeObject<T>(T serializableObject, string fileName)
    {
        if (serializableObject == null) { return; }

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            XmlSerializer serializer = new XmlSerializer(serializableObject.GetType());
            using (MemoryStream stream = new MemoryStream())
            {
                serializer.Serialize(stream, serializableObject);
                stream.Position = 0;
                xmlDocument.Load(stream);
                xmlDocument.Save(fileName);
                stream.Close();
            }
        }
        catch (Exception ex)
        {
            //Log exception here
            log.Error("SerializeObject ", ex);

        }
    }

    public T DeSerializeObject<T>(string fileName)
    {
        if (string.IsNullOrEmpty(fileName)) { return default(T); }

        T objectOut = default(T);

        try
        {
            string attributeXml = string.Empty;

            XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load(fileName);
            string xmlString = xmlDocument.OuterXml;

            using (StringReader read = new StringReader(xmlString))
            {
                Type outType = typeof(T);

                XmlSerializer serializer = new XmlSerializer(outType);
                using (XmlReader reader = new XmlTextReader(read))
                {
                    objectOut = (T)serializer.Deserialize(reader);
                    reader.Close();
                }

                read.Close();
            }
        }
        catch (Exception ex)
        {
            //Log exception here
            log.Error("DeSerializeObject ", ex);

        }

        return objectOut;
    }
