Getting values from nested object with C#

Question

I have this object and I am trying to get the lat and lon values in the location field within telemetry. I am new to c#, but know python. What I would have done in python was:

item.details["telemetry"].location.lat

Can someone please show me how this is supposed to be done in c#?

"details": {
            "asset": {
                "id": "5ca12266-35fe-4f75-8593-588fba777d6d",
                "name": "ZS-FOO"
            },
            "assetType": {

Answer 1

As i said in comment download Newtonsoft.Json

JObject data= JObject.Parse(data);
JToken details = data["details"];

string lat = details["telemetry"]["location"]["lat"].ToString();

Firstly, generate models for your data. You can do it manually by creating classes or if you are in Visual Studio, this would be helpful:

Edit=> Paste Special=> Paste JSON as class. This will generate the classes for you.

Afterwords, go with Json.NET or any other library to parse your file:

public class Program{ 
      static void Main (string[] args){
      var client = new WebClient();
      var jsonString = client.DownloadString("Your link to Json file");
      var response= JsonConvert.DeserializeObject</*Json Class*/>(jsonString);
      //Now you can retrieve the data like this:
      var lat = response.details.telemetry.location.lat;
    }
}

Don't forget to import:

using System.Net;
using Newtonsoft.Json;
