  "age": 30,
  "address": {
    "street": "123 Street",
    "city": "New York"
  }
}

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 Street\",\"city\":\"New York\"}}";
Person person = JsonConvert.DeserializeObject<Person>(json);

string street = person.Address.Street;
