在C#中的反序列化(.net json)或序列化(XmlSerializer)期间填充空值

public class Person
{
    public string Name { get; set; } = string.Empty;
    public int Age { get; set; } = 0;
    public DateTime BirthDate { get; set; } = DateTime.MinValue;
}

using Newtonsoft.Json;

// 反序列化
string json = "{\"Name\":\"John\",\"Age\":25}";
Person person = JsonConvert.DeserializeObject<Person>(json);

// 序列化
Person person = new Person { Name = "John", Age = 25 };
string json = JsonConvert.SerializeObject(person);

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

// 反序列化
XmlSerializer serializer = new XmlSerializer(typeof(Person));
using (StreamReader reader = new StreamReader("person.xml"))
{
    Person person = (Person)serializer.Deserialize(reader);
}

// 序列化
Person person = new Person { Name = "John", Age = 25 };
XmlSerializer serializer = new XmlSerializer(typeof(Person));
using (StreamWriter writer = new StreamWriter("person.xml"))
{
    serializer.Serialize(writer, person);
}
