使用嵌套类c#实现复杂的反序列化json

using Newtonsoft.Json;

public class RootObject
{
    public string Name { get; set; }
    public int Age { get; set; }
    public Address Address { get; set; }
    public List<Contact> Contacts { get; set; }
}

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

public class Contact
{
    public string Type { get; set; }
    public string Value { get; set; }
}

string json = "{\"Name\":\"John\",\"Age\":30,\"Address\":{\"Street\":\"123 Main St\",\"City\":\"New York\",\"Country\":\"USA\"},\"Contacts\":[{\"Type\":\"Email\",\"Value\":\"john@example.com\"},{\"Type\":\"Phone\",\"Value\":\"123-456-7890\"}]}";

RootObject obj = JsonConvert.DeserializeObject<RootObject>(json);
