如何从C#序列化特定的Json对象

using System;
using System.Text.Json;

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

public class Program
{
    public static void Main()
    {
        // 创建一个Person对象
        var person = new Person { Name = "John", Age = 30 };

        // 将Person对象序列化为Json字符串
        string json = JsonSerializer.Serialize(person);

        Console.WriteLine(json); // 输出: {"Name":"John","Age":30}

        // 将Json字符串反序列化为Person对象
        var deserializedPerson = JsonSerializer.Deserialize<Person>(json);

        Console.WriteLine(deserializedPerson.Name); // 输出: John
        Console.WriteLine(deserializedPerson.Age); // 输出: 30
    }
}
