Unable to convert Json String to Json Object in c#

Question

I have an Json string which is receiveCount({\\"url\\":\\"http://www.google.com\\",\\"count\\":75108})

My complete Method is

public void GetPinCount(string url)
        {
            string QUrl = "https://api.pinterest.com/v1/urls/count.json?callback=receiveCount&url=" + url;
            System.Net.HttpWebRequest Request = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(QUrl);
            Request.ContentType = "text/json";
            Request.Timeout = 10000;
            Request.Method = "GET";
            string content;
            using (WebResponse myResponse = Request.GetResponse())
            {
                using (System.IO.StreamReader sr = new System.IO.StreamReader(myResponse.GetResponseStream(), System.Text.Encoding.UTF8))
                {
                    content = sr.ReadToEnd();
                }
            };
           var json = JObject.Parse(content);
           var share_count = json["receiveCount"]["count"].ToString();
           Console.WriteLine("Share Count :" + share_count);
        }

When I am trying to access the count i am getting an exception like

Unexpected character encountered while parsing value: r. Path '', line 0, position 0.

Please tell me how this can be done.

Answer 1

Your string is not valid JSON :

receiveCount(`{\"url\":\"http://www.google.com\",\"count\":75108}`)

The valid JSON part is the parameter :

{"url":"http://www.google.com","count":75108}

You must extract the valid JSON part from your string to deserialize it.

Answer 2

You are calling the wrong property.

You should use

var share_count = json["count"].ToString();

instead of,

var share_count = json["receiveCount"]["count"].ToString();

Code to use with response:

var json = JObject.Parse (content);
var share_url = json["url"];
Console.WriteLine ("Share URL:" + share_url);
var share_count = json["count"];
Console.WriteLine ("Share Count:" + share_count);

EDIT 1:

// Gets only the JSON string we need
content = content.Replace ("receiveCount(", "");
content = content.Remove (content.Length - 1);

// Converts JSON string to Object
var json = JObject.Parse (content);
var share_url = json["url"];
Console.WriteLine ("Share URL:" + share_url);
var share_count = json["count"];
Console.WriteLine ("Share Count:" + share_count);
