I have some json like this:
{
"status": "OK",
"result": {
"#type": "address_result__201301",
"barcode": "1301013030001010212212333002003031013",
"bsp": "044",
"dpid": "99033785",
"postcode": "4895",
"state": "QLD",
"suburb": "COOKTOWN",
"city": null,
"country": "AUSTRALIA"
},
"search_date": "03-12-2014 15:31:03",
"search_parameters": {},
"time_taken": 636,
"transaction_id": "f8df8791-531e-4043-9093-9f35881f6bb9",
"root_transaction_id": "a1fa1426-b973-46ec-b61b-0fe5518033de"
}
Then I created some classes:
public class Address
{
public string status { get; set; }
public Result results { get; set; }
public string search_date { get; set; }
public SearchParameters search_parameters { get; set; }
public int time_taken { get; set; }
public string transaction_id { get; set; }
public string root_transaction_id { get; set; }
}
public class Result
{
public string #type { get; set; }
public string barcode { get; set; }
public string bsp { get; set; }
public string dpid { get; set; }
public string postcode { get; set; }
public string state { get; set; }
public string suburb { get; set; }
public string city { get; set; }
public string country { get; set; }
}
public class SearchParameters
{
}
Finally, I use these code to get Json data:
string result = "Above json";
JavaScriptSerializer json = new JavaScriptSerializer();
Address add = json.Deserialize<Address>(result);
I see that, add.status, add.search_date... etc have values, but add.results is null.
What is wrong with my code?
I think the issue is using #type as illegal identifier. Try using [DataMember(Name = "#type")] before public string #type { get; set; }. Add a [DataContract] before public class Address.
Hence, your final code will be,
[DataContract]
public class Result
{
[DataMember(Name = "#type")]
public string #type { get; set; }
public string barcode { get; set; }
public string bsp { get; set; }
public string dpid { get; set; }
public string postcode { get; set; }
public string state { get; set; }
public string suburb { get; set; }
public string city { get; set; }
public string country { get; set; }
}

I have a JSON response which i generated a model from. the JSON data has various branches with data as shown below.

I have various branches in this JSON response which i need to use. i generated a model class from this JSON as shown below
// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
public class Customer
{
public object district { get; set; }
public string feeder { get; set; }
public string feeder_code { get; set; }
public string transformer { get; set; }
public string dss_code { get; set; }
public string database_match { get; set; }

public string oldaccountnumber { get; set; }
public string odoo_account_number { get; set; }
public string customername { get; set; }
public string address { get; set; }
public string phone { get; set; }
public string tarrif { get; set; }
public string tariff_category { get; set; }
public string service_band { get; set; }
public string status { get; set; }
public string status_period { get; set; }
public object payment_status { get; set; }
public string arrears { get; set; }
public string long_x { get; set; }
public string lat_y { get; set; }
public TransactionalDetails transactional_details { get; set; }
}
public class Customer2
{
public string accountNumber { get; set; }
public string meterNumber { get; set; }
public string phoneNumber { get; set; }
public string lastName { get; set; }
public string address { get; set; }
public string city { get; set; }
public string district { get; set; }
public string userCategory { get; set; }
public string customerType { get; set; }
public string paymentPlan { get; set; }
public int vat { get; set; }
public string tariffCode { get; set; }
public double tariffRate { get; set; }
public int arrearsBalance { get; set; }
public int billedAmount { get; set; }
public object billedDate { get; set; }
public string lastPayDate { get; set; }
public Lastpayment lastpayment { get; set; }
}
public class Lastpayment
{
public string transactionRef { get; set; }
public int units { get; set; }
public string transactionDate { get; set; }
public string transactionId { get; set; }
public int transactionBookId { get; set; }
public int amountPaid { get; set; }
public int mscPaid { get; set; }
public string invoiceNumber { get; set; }
}
public class Queryresult
{
public string responseMessage { get; set; }
public Customer customer { get; set; }
public int responseCode { get; set; }
public string status { get; set; }
}
public class Result
{
public ObservableCollection<Customer> customers { get; set; }
public int row_count { get; set; }
}
public class Root
{
public bool error { get; set; }
public Result result { get; set; }
}
public class TransactionalDetails
{
public Queryresult queryresult { get; set; }
public bool status { get; set; }
}
Afterwards i used the C# code to deserialize the JSON as shown below
Root myroot = JsonConvert.DeserializeObject<Root>(readTask);
ObservableCollection<Customer> data = myroot.result.customers;
This works fine, however, i am stuck with just customer Data. I want to be able to get the Transactional details (Customer2) and Lastpayment branches in a collection view. how can i achieve this? Thanks
You can parse your json and read it by linq. ToObject method help you to convert nodes to specific class.
I have taken json text in InputJson variable and then paresed it.
var parsed = JObject.Parse(InputJson);
var innerNodes = JArray.Parse(parsed["result"]["customers"].ToString());
var CustomerList = innerNodes.Select(x => x.ToObject<Customer>()).ToList();
And if you need just some of properties you can use in this way
var CustomerList = innerNodes.Select(x =>
new Customer
{
district = x["district"],
feeder = x["feeder"].ToString(),
transactional_details =x["transactional_details"].ToObject<TransactionalDetails>()
})
.ToList();
If you have different nodes in your object , you can call nodes and check them not be null!
var CustomerList = innerNodes.Select(x => new
{
district = x["district"],
feeder = x["feeder"].ToString(),
transactional_details =x["transactional_details"]?.ToObject<TransactionalDetails>(),
Lastpayment = x["transactional_details"]?["queryresult"]?["customer"]?["lastpayment"]?.ToObject<Lastpayment>(),
billedAmount = x["transactional_details"]?["queryresult"]?["customer"]?["billedAmount"] ?.ToString()
}).ToList();
Customers is an array object so you must iterate through this array.
For example this would work:
Root myroot = JsonConvert.DeserializeObject<Root>(json);
myroot.result.customers.ToList().ForEach(c =>
{
Console.WriteLine(c.transactional_details.queryresult.customer.lastpayment.amountPaid);
});
Looking at Locals in vs debugger for
var customers = myroot.result.customers.ToList();
we get this:
fix Queryresult class by changing Customer to Customer2
public class Queryresult
{
public string responseMessage { get; set; }
public Customer2 customer { get; set; }
public int responseCode { get; set; }
public string status { get; set; }
}
now you can get a lastpayment
Root myroot = JsonConvert.DeserializeObject<Root>(readTask);
LastPayment lastPayment = myroot.result.customers
.Select(c=>c.transactional_details.queryresult.customer.lastpayment).FirstOrDefault();
how to use
var amountPaid = lastPayment.amountPaid; //1000
var invoiceNumber = lastPayment.invoiceNumber; //17289583
I'm trying to create a basic Xamarin Forms app that can list available gateways on my PFsense firewall, Show the available gateway and change this to another gateway to route through if required. The problem I have is I cannot deserialize the JSON in C# because each object has a different object name:

var json = await response.Content.ReadAsStringAsync();
var gateways = JsonConvert.DeserializeObject<Data>(json);

The problem is in the gateways variable, all of the properties are null. I think because of how the JSON is structured in the response, it might not be possible in C#, but perhaps there's another way of going about it?

I have this Json:

I deserialize with :
var result = JsonConvert.DeserializeObject<RootObject>(Json);
var price = result.trades.Select(p => p.price).ToList();
price.ForEach(Console.WriteLine);
It works. I can access "price" in "trades", but I do not know how to access the "price" in "takeProfitOrder". I need the value of "price" from "takeProfitOrder" in to a list. I am sure it is something very simple but I cannot figure out how to do it, even after looking at some similar examples.
Can somebody please help me?
It's simple
result.trades.Select(p => p.takeProfitOrder.price)
You should understand better from this example
foreach (Trade trade in result.trades)
{
TakeProfitOrder takeProfitOrder = trade.takeProfitOrder;
Console.WriteLine(takeProfitOrder.price);
}
what would the C# class definition look like to represent this JSON data?

You can use a site like this http://jsonutils.com/
where you paste in your json and it constructs your classes for you. The result of your JSON produced...
public class AlternateWebsite
{
public string website { get; set; }
}
public class AlternateEmail
{
public string email { get; set; }
}
public class Address
{
public string street { get; set; }
public string city { get; set; }
public string postalCode { get; set; }
public string state { get; set; }
}
public class RankingKeyword
{
public string keyword { get; set; }
public string localArea { get; set; }
}
public class Root
{
public string accountId { get; set; }
public string website { get; set; }
public IList<AlternateWebsite> alternateWebsites { get; set; }
public string email { get; set; }
public IList<AlternateEmail> alternateEmails { get; set; }
public Address address { get; set; }
public IList<RankingKeyword> rankingKeywords { get; set; }
}
You could convert this with a service like http://json2csharp.com/. Enter the JSON and it will spit out C# model classes. Then, add them either as a class, or using Entity Framework (depending on your objective) into your project.
C# version:
public class AlternateWebsite
{
public string website { get; set; }
}
public class AlternateEmail
{
public string email { get; set; }
}
public class Address
{
public string street { get; set; }
public string city { get; set; }
public string postalCode { get; set; }
public string state { get; set; }
}
public class RankingKeyword
{
public string keyword { get; set; }
public string localArea { get; set; }
}
public class RootObject
{
public string accountId { get; set; }
public string website { get; set; }
public List<AlternateWebsite> alternateWebsites { get; set; }
public string email { get; set; }
public List<AlternateEmail> alternateEmails { get; set; }

public string primary_organisation { get; set; }
public string emailAddress { get; set; }
public List<Editorship2> editorship { get; set; }
}
public class Properties
{
public List<Jci> jci { get; set; }
public List<Sid> sid { get; set; }
}
public class RootObject
{
public Properties properties { get; set; }
}
You can then access your editorial values like this:
JavaScriptSerializer serializer = new JavaScriptSerializer();
var collection = serializer.Deserialize<RootObject>(jsonString);
foreach (var j in collection.properties.sid)
{
Console.Write(j.editorship);
}
On a side note, you should consider using names that are more readable then jci and sid
