JSON parsing in c# item is not an array

Question

I am trying to parse a JSON string, that looks like that:

{
    "totalCreditsRemoved": 1,
    "invalidReceivers": [],
    "ids": [100070531],
    "validReceivers": ["+33635938286"]
}

I retrieve this from a web API, and stock it as a String:

var reader = new StreamReader(respStream);
String result = reader.ReadToEnd().Trim();
response = result;

Response is a public string

Then, in another method: I try to parse my json string:

var json = response;
var objects = JArray.Parse(json);

foreach (JObject root in objects)
{
    foreach (KeyValuePair<String, JToken> app in root)
    {
        totalCreditsRemoved = (String)app.Value["totalCreditsRemoved"];
        invalidReceivers = (String)app.Value["invalidReceivers"];
        ids = (String)app.Value["ids"];
        validReceivers = (String)app.Value["validReceivers"];
    }
}

But I always get this error:

JsonReaderException: Error reading JArray from JsonReader. Current JsonReader item is not an array: StartObject. Path '', line 1, position 1.

The error occurs at this line:

var objects = JArray.Parse(json);

I don't understand how to fix this ? Isn't OVHjson already an array Thanks in advance!

The response does not represent an array, so it can't be parsed by JArray.Parse. — Tomalak

Exactly what it says. From what you posted, the JSON is an object, not an array. — Evan Trimboli

Use the correct method - if the content is an object use JObject.Parse. Better yet, create a DTO (ie a class with the properties you want) and deserialize the entire object at once, eg var myDTO = JsonConvert.DeserializeObject<MyDTO>(input); Console.WriteLine(myDTO.totalCredits); — Panagiotis Kanavos

looks like your api method is not consistent in the response format (sometimes it returns array, sometimes it returns object). That's a very kind of bad design I've encountered with when working with some partners. — King King

No need for JArray.Parse as it is not a array ..and is doing an overkill..hence the error..

var objects = JObject.Parse(json);

will do the job

and to extract

totalCreditsRemoved = (String)objects.Value["totalCreditsRemoved"];
invalidReceivers = (String)objects.Value["invalidReceivers"];
ids = (String)objects.Value["ids"];
validReceivers = (String)objects.Value["validReceivers"];

 dynamic jsonObj = JsonConvert.DeserializeObject(responseFromServer);
 foreach (var obj in obj1.Properties())
 {
     if (obj.Name == "rewardConfirmation") {
         foreach (var obj2 in obj.Value)
         {
             MessageBox.Show(obj2.ToString());
         }
     }
 }
