如何在C#中解析这种类型的JSON (嵌套)

string json = "{\"name\":\"John\",\"age\":30,\"address\":{\"street\":\"123 Main St\",\"city\":\"New York\"}}";
JObject obj = JObject.Parse(json);

string name = (string)obj["name"];
int age = (int)obj["age"];
string street = (string)obj["address"]["street"];
string city = (string)obj["address"]["city"];

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

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

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