使用System.Text.Json将json反序列化为多个类

using System.Text.Json;

{
  "name": "John Doe",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York"
  }
}

public class Address
{
    public string Street { get; set; }
    public string City { get; set; }
}

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

string jsonString = "{\"name\":\"John Doe\",\"age\":30,\"address\":{\"street\":\"123 Main St\",\"city\":\"New York\"}}";
Person person = JsonSerializer.Deserialize<Person>(jsonString);

Console.WriteLine(person.Name); // 输出：John Doe
Console.WriteLine(person.Age); // 输出：30
Console.WriteLine(person.Address.Street); // 输出：123 Main St
Console.WriteLine(person.Address.City); // 输出：New York
