将特定的.net对象公开为JSON

using Newtonsoft.Json;

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

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

    string json = JsonConvert.SerializeObject(person);

    Console.WriteLine(json);
}

{"Name":"John","Age":30}
