Parsing Json Data string And Retrieve Specific Element

My JSON string is:

string b = "\"{\"Response\":[{\"ResponseCode\":\"0\",\"ResponseMessage\":\"71a88836-57f0-4b0e-a59c-071ea6d6f1de\"}]}\"";

I want to retrieve value of ResponseCode and ResponseMessage.

When I tried something like this to parse my JSON string

var userObj = JObject.Parse(b);

I am getting Error such as:

Newtonsoft.Json.JsonReaderException: 'Error reading JObject from JsonReader. Current JsonReader item is not an object: String. Path '', line 1, position 3.'

Please help me to retrieve ResponseCode And ResponseMessage from the given string.

You need to trim the outer doublequotes, otherwise it is not a valid json format

var userObj = JObject.Parse(b.Trim('"'));

Then you can retrieve the data either by declaring a class matching the json format and deserializing it, or just accessing the properties dynamically

var response = (JArray)userObj["Response"];
string responseCode = response[0]["ResponseCode"].Value<string>();
string responseMessage = response[0]["ResponseMessage"].Value<string>();

You should use create a class that matches the properties you expect. I think you want a Response-class with property ResponseCode and ResponseMessage.

If that's the case, you should remove the outer "Response" tag. Also the backslash should be removed and the double quotes should be replaced by single quotes.

Try this:

class Response
{
    public string ResponseCode { get; set; }
    public string ResponseMessage { get; set; }
}
static void Main(string[] args)
{
    string body = @"{'ResponseCode':0,'ResponseMessage':'71a88836-57f0-4b0e-a59c-071ea6d6f1de'}";
    var response = JsonConvert.DeserializeObject<Response>(body );
}
