Json Net hierarchy class - json

Question

I am using Newtonsoft.Json on my VB.Net, and having trouble with json deserialization.
Totally a noob on this. A simple class hierarchy, I can do it... but a more complex like the one below, totally an idiot.
Can someone help me to build the serialize class hierarchy from this JSON??
{
"user": {
"user_id": 123456,
"total": 100,
"rewards": 0
},
"workers": {
"1": {
"worker_name": "rainfall_home",
"rate": 0,
"shares": 0
},
"2": {
"worker_name": "rainfall_office",
"rate": 7358.71,
"shares": 96564
},
"3": {
"worker_name": "rainfall_rig",
"rate": 0,
"shares": 77208
},
"4": {
"worker_name": "rainfall_s11",
"rate": 178365.22,
"shares": 3760356
},
"5": {
"worker_name": "rainfall_s12",
"rate": 196537.7,
"shares": 4152710
}
},
"total": {
"total_user": 5,
"record_date": 2
}
}
And how do I get the workers length(total) and loop with it, so i can get record for each worker? Since worker can keep adding up.
Thanks in advance.

Answer 1

As you are trying to get the total number of workers and you are saying that workers can keep adding up, then I would propose you to restructure your JSON (if you have scope to modify) so that the workers can be managed as an array instead of adding it like an object each time a new worker is needed to add to JSON. Please see the proposed JSON below:
{
"user": {
"user_id": 123456,
"total": 100,
"rewards": 0
},
"workers": [
{
"worker_name": "rainfall_home",
"rate": 0,
"shares": 0
},
{
"worker_name": "rainfall_office",
"rate": 7358.71,
"shares": 96564
},
{
"worker_name": "rainfall_rig",
"rate": 0,
"shares": 77208
},
{
"worker_name": "rainfall_s11",
"rate": 178365.22,
"shares": 3760356
},
{
"worker_name": "rainfall_s12",
"rate": 196537.7,
"shares": 4152710
}
],
"total": {
"total_user": 5,
"record_date": 2
}
}
Now your new classification is below:
public class RootObject
{
public User user { get; set; }
public List<Worker> workers { get; set; }
public Total total { get; set; }
}
public class User
{
public int user_id { get; set; }
public int total { get; set; }
public int rewards { get; set; }
}
public class Worker
{
public string worker_name { get; set; }
public double rate { get; set; }
public int shares { get; set; }
}
public class Total
{
public int total_user { get; set; }
public int record_date { get; set; }
}
Now you can easily loop through each worker to get one's details like below:
string json = "YOUR_JSON_STRING";
RootObject rootObject = JsonConvert.DeserializeObject<RootObject> ( json );
Console.WriteLine("Total no. of workers: {0}", rootObject.workers.Count);
foreach ( Worker worker in rootObject.workers )
{
Console.WriteLine("Name: {0}, Rate: {1}, Shares: {2}", worker.worker_name, worker.rate.ToString("F2", CultureInfo.InvariantCulture), worker.shares);
}

Answer 2

If your JSON data is from an outside API, then you can classify it like below:
public class RootObject
{
public User user { get; set; }
public Dictionary<string, Worker> workers { get; set; }
public Total total { get; set; }
}
public class User
{
public int user_id { get; set; }
public int total { get; set; }
public int rewards { get; set; }
}
public class Worker
{
public string worker_name { get; set; }
public double rate { get; set; }
public int shares { get; set; }
}
public class Total
{
public int total_user { get; set; }
public int record_date { get; set; }
}
Now you can easily loop through each worker to get one's details like below:
string json = "YOUR_JSON_STRING";
RootObject rootObject = JsonConvert.DeserializeObject<RootObject> ( json );
Console.WriteLine("Total no. of workers: {0}", rootObject.workers.Count);
foreach ( KeyValuePair<string, Worker> worker in rootObject.workers )
{
Console.WriteLine("Name: {0}, Rate: {1}, Shares: {2}", worker.Value.worker_name, worker.Value.rate.ToString("F2", CultureInfo.InvariantCulture), worker.Value.shares);
}
