Вы можете сделать это с помощью пользовательского JsonConverter.
public class CustomerJsonConverter : JsonConverter
{
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
if (value is Customer customer)
{
var token = new JObject
{
["id"] = customer.Id,
["userName"] = customer.UserName,
["address"] = customer.Address.Address,
["address2"] = customer.Address.Address2,
["city"] = customer.Address.City,
["state"] = customer.Address.State,
["zip"] = customer.Address.ZIP
};
token.WriteTo(writer);
}
else
{
throw new InvalidOperationException();
}
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
var obj = JToken.ReadFrom(reader);
if (obj.Type != JTokenType.Object)
{
return null;
}
return new Customer
{
Id = (long) obj["id"],
UserName = (string) obj["userName"],
Address = obj.ToObject<AddressModel>()
};
}
public override bool CanRead => true;
public override bool CanConvert(Type objectType)
{
return objectType == typeof(Customer);
}
}
Вместе с JsonConverterAttribute для класса Customer.
[JsonConverter(typeof(CustomerJsonConverter))]
public class Customer
{
public long Id { get; set; }
public string UserName { get; set; }
public AddressModel Address { get; set; }
}
public class AddressModel
{
public string Address { get; set; }
public string Address2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string ZIP { get; set; }
}
И использовать как таковой:
var customer = JsonConvert.DeserializeObject<Customer>(customerJson);
альтернативно, вы могли бы просто иметь промежуточную модель отображения.
public class CustomerFlattened
{
public long Id { get; set; }
public string UserName { get; set; }
public string Address { get; set; }
public string Address2 { get; set; }
public string City { get; set; }
public string State { get; set; }
public string ZIP { get; set; }
public Customer ToCustomer()
{
return new Customer
{
Id = Id,
UserName = UserName,
Address = new AddressModel
{
Address = Address,
Address2 = Address2,
City = City,
State = State,
ZIP = ZIP
}
};
}
public static CustomerFlattened FromCustomer(Customer customer)
{
return new CustomerFlattened
{
Id = customer.Id,
UserName = customer.UserName,
Address = customer.Address.Address,
Address2 = customer.Address.Address2,
City = customer.Address.City,
State = customer.Address.State,
ZIP = customer.Address.ZIP
};
}
}
И использовать как таковой:
var customer =
JsonConvert.Deserialize<CustomerFlattened>(
jsonOriginal
)
.ToCustomer();
var customerFlattened = CustomerFlattened.FromCustomer(customer);
var jsonConverted = JsonConvert.Serialize(customerFlattened );
