使用obj.property和obj.property[index]使用JsonPropertyName()呈现JSON输入

using System.Text.Json.Serialization;

public class Person
{
    [JsonPropertyName("name")]
    public string Name { get; set; }

    [JsonPropertyName("age")]
    public int Age { get; set; }
}

using System;
using System.Text.Json;

public class Program
{
    public static void Main()
    {
        Person person = new Person
        {
            Name = "John",
            Age = 30
        };

        string json = JsonSerializer.Serialize(person);
        Console.WriteLine(json);
        // Output: {"name":"John","age":30}

        Person deserializedPerson = JsonSerializer.Deserialize<Person>(json);
        Console.WriteLine($"Name: {deserializedPerson.Name}, Age: {deserializedPerson.Age}");
        // Output: Name: John, Age: 30
    }
}
