I have this json:
{
"test":
{
"id": 107537,
"name": "test",
"profileIconId": 785,
"revisionDate": 1439997758000,
"summonerLevel": 30
}
}
I want to get the field named summonerLevel.
I have tried to convert this json to a string and then search for summonerLevel, but I know that this solution is not okay.
I'm using Json.NET.
You can use the dynamic keyword
dynamic obj = JsonConvert.DeserializeObject(json);
Console.WriteLine(obj.unashamedohio.summonerLevel);
You have a couple of possibilities (as already showed in the other answers). Another possibility would be to use the JObject and JProperty properties provided from Json.Net, in order to directly fetch the value like this:
var jsonObject = (JObject)JsonConvert.DeserializeObject(json);
var unashamedohio = (JObject)(jsonObject.Property("unashamedohio").Value);
var summonerLevel = unashamedohio.Property("summonerLevel");
Console.WriteLine(summonerLevel.Value);
Yet another possibility would be to create a typed model of the JSON structure:
public class AnonymousClass
{
public UnashamedOhio unashamedohio { get; set; }
}
public class UnashamedOhio
{
public int summonerLevel { get; set; }
}
and use it to retrieve the value:
var ao = JsonConvert.DeserializeObject<AnonymousClass>(json);
Console.WriteLine(ao.unashamedohio.summonerLevel);
Both solutions print the same value: 30.
IMO you should use always typed models when possible and if you do a lot of value fetching from a JSON structures. It provides error checking in the IDE (as opposed to dynamic) which pay-offs at runtime.
I'm assuming this json is stored in a string, let's say called json... so try
string json = "...";
JObject obj = JsonConvert.DeserializeObject<JObject>(json);
JObject innerObj = obj["test"] as JObject;
int lolSummorLvl = (int) innerObj["summonerLevel"];
This worked for me
Found here - How do you read a simple value out of some json using System.Text.Json?
var jsonResult = JsonSerializer.Deserialize<JsonElement>(apiResponse).GetProperty("collection");
return jsonResult.EnumerateArray();
Code with HTTPCLient GET:
using (var httpClient = new HttpClient())
{
// Headers
httpClient.DefaultRequestHeaders.Add("X-AppSecretToken", "sJkvd4hgr45hhkidf");
httpClient.DefaultRequestHeaders.Add("X-AgreementGrantToken", "r55yhhsJkved4ygrg5hssdhkidf");
using (var response = await httpClient.GetAsync("https://restapi/customers"))
{
string apiResponse = await response.Content.ReadAsStringAsync(); // Result
var jsonResult = JsonSerializer.Deserialize<JsonElement>(apiResponse).GetProperty("collection");
return jsonResult.EnumerateArray();
}
}
With .NET 8 the easiest method I've found is using JsonSeralizer.Deserialize. This works similarly to using dynamic DeserializeObject on older versions.
Example to get id, sys_id and name from JSON:
JsonObject? _departmentJson = JsonSerializer.Deserialize<JsonObject>(deparmentCallResult)!;
_departmentID = (string)_departmentJson["result"]!["id"]!;
_department_sys_ID = (string)_departmentJson["result"]!["sys_id"]!;
_department_Name = (string)_departmentJson["result"]!["name"]!;
