有如下XML，Index_0-Index_N为动态的，N为可变数，如何将对象NoneXML序列化为XML，以及如何将XML内容反序列化为对象NoneXML？

1、XML内容

XML内容也可能是：

2、采用以下代码可以序列化和反序列化，但无法对应具体动态元素N个索引的XML内容，从<Index_0> 到 <Index_N> 无法动态序列化和反序列化

public class NoneXML
{
[XmlAnyElement] public List<XmlElement> Index_N_Element { get; set; }
}

3、采用固定呆板的代码，无法序列化和反序列化，获得所有动态的<Index_0> 到 <Index_N>数据，以下代码只能从<Index_0> 到 <Index_4>

public class NoneXML
{
[XmlElement("Index_0")] public IndexN { get; set; }

[XmlElement("Index_1")] public IndexN { get; set; }

[XmlElement("Index_2")] public IndexN { get; set; }

[XmlElement("Index_3")] public IndexN { get; set; }

[XmlElement("Index_4")] public IndexN { get; set; }

[XmlElement("Index_5")] public IndexN { get; set; }
}

4、IndexN的子Element

public class IndexN
{
/// <summary>是否采用汇总</summary>
[XmlElement("UseInSummary")] public int UseInSummary { get; set; } = 1;
/// <summary>是否左岸开始</summary>
[XmlElement("BeginLeft")] public int BeginLeft { get; set; }
/// <summary>是否已分段</summary>
[XmlElement("IsSubSectioned")] public int IsSubSectioned { get; set; }
/// <summary>文件名</summary>
[XmlElement("FileName")] public string FileName { get; set; }
/// <summary>断面数</summary>
[XmlElement("TransectNmb")] public int TransectNmb { get; set; }
/// <summary>总集合数</summary>
[XmlElement("TotalNmbEnsembles")] public int TotalNmbEnsembles { get; set; }
/// <summary>不良集合总数</summary>
[XmlElement("TotalBadEnsembles")] public int TotalBadEnsembles { get; set; }
/// <summary>丢失集合总数</summary>
[XmlElement("TotalLostEnsembles")] public int TotalLostEnsembles { get; set; }

}

5、序列化

Console.WriteLine();
Console.WriteLine("None对象序列化为XML字符串----------------控制台显示--------------------");
string xml;
XmlSerializer serializer = new XmlSerializer(typeof(NoneXML));
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
ns.Add("", "");//命名空间设为空

using (StringWriter writer = new StringWriter())
{
serializer.Serialize(writer, NoneXML, ns);//, ns
xml = writer.ToString();

Console.WriteLine(xml);//控制台显示
}

6、反序列化

Console.WriteLine();
Console.WriteLine("XML 字符串反序列化为 NoneXML 对象--------------------------------------");
NoneXML newNoneXML;
using (StringReader reader = new StringReader(xml))
{
newNoneXML = (NoneXML)serializer.Deserialize(reader);
}

Console.WriteLine(newNoneXML.Index_0.UseInSummary);//要具体获得<Index_0> 到 <Index_N>以下的IndexN对象值。
