C# Looking for help how to deserialize this kind of json

Question

to start off, I am a beginner. I have been searching for something that looks something like this problem without managing to solve the problem. And now I have been stuck with this problem for a while. I am using an API from our local post delivery where we can get information such as deliverytime, address etc in a json link. But in this case the json looks a bit different and I do not know how to work with it.

I would be really happy if someone could explain to me how I can access the data such as deliverdate and address. Right now when I try, it only shows the value is null.

I use json.net for deserializing

Below you can see how it looks like..

private async void button_Click(object sender, RoutedEventArgs e)
{
    string url = "https://api2.postnord.com/rest/shipment/v1/trackandtrace/findByIdentifier.json?id=...";

    HttpClient client = new HttpClient(); 
    string date = await client.GetStringAsync(new Uri(url));
    var jarray = JsonConvert.DeserializeObject<Rootobject>(date);

Answer 1

Like the other answers state, JsonConvert.DeserializeObject<>() is the method you need. After that, you just need to traverse the deserialized data structure.

As to why you are getting NULL after you attempt to deserialize, NULL is returned if the deserializtion fails. Typically when the data is in a bad format or character case fails to match. But for the sample JSON you supplied, it deserilized correctly for me using your classes.

Rootobject root = JsonConvert.DeserializeObject<Rootobject>(data);
if (root == null ||
    root.TrackingInformationResponse == null ||
    root.TrackingInformationResponse.shipments == null ||
    root.TrackingInformationResponse.shipments.Length == 0)
{
    throw new Exception();
}
Shipment shipment = root.TrackingInformationResponse.shipments[0];

if (shipment.consignee == null || shipment.consignee.address == null)
{
    throw new Exception();
}

Console.WriteLine("Consignee: {0}", shipment.consignee);
Console.WriteLine("Estimated Time of Arrival: {0}", shipment.estimatedTimeOfArrival);

Answer 2

You can try with

var jarray = JsonConvert.DeserializeObject<Rootobject>(date, 
  new IsoDateTimeConverter { DateTimeFormat = "yyyy-MM-ddTHH:mm:ss" });

Answer 3

Here's an existing post that might help you.

Deserializing JSON to .NET object using Newtonsoft (or LINQ to JSON maybe?)

Here's some info on Newtonsoft. http://www.newtonsoft.com/json/help/html/deserializeobject.htm

Example of usage:

Newtonsoft.Json.JsonConvert.DeserializeObject()
