Get API Return JSON Payload in C#

Question

I created a Web API and it needs to read the response in header with json content, therefore I use code below:

HttpRequestMessage re = Request;
var payLoadJson = re.Content;
string jsonContent = payLoadJson.ReadAsStringAsync().Result;
var test = JObject.Parse(jsonContent);

And here is the response of var test

{{
  "pushToken": "AAABBBCCC"
}}

Can any body tell me how to get the value of pushToken?

JObject.Parse(jsonContent)['pushToken'] always get null because of double braces.

You can remove your first and last char from the json string to make it a valid JSON — Mohit S

Your string in valid Json format:

{
    "pushToken": "AAABBBCCC"
}

Getting the payload

var pushToken = JObject.Parse(json)["pushToken"];

(Also note that pushtoken is between double quotes not single quotes as per your example, you should get an error with singles once)

or

dynamic obj = JsonConvert.DeserializeObject(json);

var pushToken = obj.pushToken;

As a side note:

In case you receive that bad invalid Json like you described ... I would actually have no idea how that's even possible. Then remove the two braces before parsing or deserializing.

json = json.Trim();
json = json.Substring(1, json.Length - 2);

Thank you for your detail ans, it is work now! The invalid Json is come from Apple wallet return HTTP content, and I am still finding what Apple return data exactly. Once again, thank you so much!

@YukwongTsang your welcome. But any API should return you valid Json after all.
