将XML字符串反序列化为c#对象，生成可以为空的数据

using System;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

// 定义C#类来表示XML中的数据结构
public class MyData
{
    public int? Id { get; set; }
    public string Name { get; set; }
    public DateTime? Date { get; set; }
}

public class Program
{
    public static void Main(string[] args)
    {
        // XML字符串
        string xmlString = "<MyData><Id>1</Id><Name>John</Name></MyData>";

        // 创建XmlDocument对象并加载XML字符串
        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.LoadXml(xmlString);

        // 创建StringReader对象并传递XML字符串
        StringReader stringReader = new StringReader(xmlDoc.OuterXml);

        // 创建XmlSerializer对象并执行反序列化操作
        XmlSerializer serializer = new XmlSerializer(typeof(MyData));
        MyData myData = (MyData)serializer.Deserialize(stringReader);

        // 输出反序列化后的数据
        Console.WriteLine("Id: " + myData.Id);
        Console.WriteLine("Name: " + myData.Name);
        Console.WriteLine("Date: " + myData.Date);
    }
}
