将 C# 类转换为 Json

Question

How do i serialize multiple c# classes to one json string using . Be able to make the variables in the json data hold values that can change

string outputJSON = JsonConvert.SerializeObject();

i have the following classes

 public class Rootobject
    {
    public string Number { get; set; }
        public string RequestedDeviceType { get; set; }
        public string DeliveryMethod { get; set; }
        public Customer Customer { get; set; }
        public Vehicle Vehicle { get; set; }
    }

    public class Customer
    {
        public Contacts Contacts { get; set; }
        public string Name { get; set; }
        public string Number { get; set; }
        public bool OverrideData { get; set; }
    }

    public class Contacts
    {
        public string FirstName { get; set; }
        public string Name { get; set; }
        public string Email { get; set; }
        public string City { get; set; }
        public string Address { get; set; }
        public string MobilePhone { get; set; }
    }

    public class Vehicle
    {
        public string VIN { get; set; }
        public string MakeModelCode { get; set; }
        public string LicensePlate { get; set; }
        public string Make { get; set; }
        public string Model { get; set; }
        public int YearOfInitialRegistration { get; set; }
        public string MotorType { get; set; }
        public bool OverrideData { get; set; }
    }

}

They must serialize to the following structure of json structure and i must be able to capture user input and set the values into json file

{
  "Number": "xTest",
  "RequestedDeviceType": "XXXX",
  "DeliveryMethod": "XXXX",
  "Customer": {
    "Contacts": {

      "FirstName": "John",
      "Name": "Doe",
      "Email": "mail@demo.com",
      "City": "Harare",
      "Address": "XXXXX",
      "MobilePhone": "00000000"

    },
    "Name": "Peter Chaneta",
    "Number": "4567865678",
    "OverrideData": true
  },
  "Vehicle": {
    "VIN": "weryts55444554",
    "MakeModelCode": "34010",
    "LicensePlate": "SS 100 GP",
    "Make": "RANGE ROVER",
    "Model": "SPORT",
    "YearOfInitialRegistration": 2016,
    "MotorType": "Petrol",
    "OverrideData": true
  }
}

Answer 1

I am guessing you are using JSON.net. If not you can get it over the Nuget-Packet Manager.

You called your class "Contacts" are you wanting to have more than one contact? If yes, you might want to use a List on the RootObject.

Now if you use:

var data = new Rootobject();
var dataString = JsonConvert.SerializeObject(data);

You have all your data in a string as requested. From here you could write it to a file. If you want to change the data and read it again you would use something along this:

Rootobject data2 = JsonConvert.DeserializeObject<Rootobject>(dataString);

Now you could display the data somewhere or could change it through any input controls. (Website / Windows Form / XAML / Console ...)

Any other things you could find at the official documentation for json.net ( https://www.newtonsoft.com/json )

Otherwise your question is way too generic.

Answer 2

As an alternative to JSON.Net you can also use one from System.Web.Extensions namespace:

using System.Web.Extensions;


public string SerializeClassToJSON(object baseClass)
{
    var jSerializer = new JavascriptSerializer();
    var jsonString = jSerializer.Serialize(baseClass);

    return jsonString;
}

If you are okay sharing your classes with a third party online, you can use the below link to generate JSON directly from the class.
