Post a Json string in Xamarin

In my app, I am posting json string to the server in this manner:

string url = "my/url";

        HttpClient newClient = new HttpClient();



        string contentType = "application/json";

        JObject json = new JObject

        {

            { "id", "id" },

            { "apiKey", "apiKey" },

            { "EncryptedData", Data }

        };



        var jon = JsonConvert.SerializeObject(json);

        var content = new StringContent(jon, Encoding.UTF8, contentType);

        var TaskPostAsync = await newClient.PostAsync(url, content);





        if (TaskPostAsync.IsSuccessStatusCode)

        {

            var contentString = await TaskPostAsync.Content.ReadAsStringAsync();}

The response I am getting is that it is not in a Json format. Where am I going wrong. Any help would be much appreciated.
Data is a string.

By calling

 var jon = JsonConvert.SerializeObject(json);

You are serializing it twice.

JObject is already JSON so all you need to do is call .ToString to get the JSON

//...



JObject json = new JObject

{

    { "id", "id" },

    { "apiKey", "apiKey" },

    { "EncryptedData", Data }

};



var content = new StringContent(json.ToString(), Encoding.UTF8, contentType);



//...

Reference Write JSON text with JToken.ToString

Another option would be to use an anonymous object and then serialize that

//...



var model = new {

    id = "id",

    apiKey = "apiKey",

    encryptedData = Data

};



var json = JsonConvert.SerializeObject(model);

var content = new StringContent(json, Encoding.UTF8, contentType);



//...

This is what server returns. If the the hasError is false, I would get the encryptedData back from the server.
