Return <T> string for json

Its frustrating me and google is not my friend right now.

I have a GET method return parameter T 

public T GET(string path, string filter = "", string select = "")
    {
        //Check for accesstoken
        oAuthHelper.GetAccessToken();

        //request token
        var restclient = new RestClient(_url);
        RestRequest request = new RestRequest(string.Format("api/v1/{1}/{0}", path, Global._DIVISION)) { Method = Method.GET };

        request.AddHeader("Accept", "application/json");
        request.AddHeader("Content-Type", "application/text");

        //GUID FILTER"
        //string.Format("ID eq guid'{0}'",  "6526d916-173b-4c23-b3da-068c70d6a867")

        if (!string.IsNullOrEmpty(filter))
            request.AddParameter("$filter", filter, ParameterType.QueryString);

        if (!string.IsNullOrEmpty(select))
            request.AddParameter("$select", select, ParameterType.QueryString);

        request.AddParameter("Authorization", string.Format("Bearer " + Global._ACCESTOKEN),
        ParameterType.HttpHeader);

        var tResponse = restclient.Execute(request);
        var responseJson = tResponse.Content;



        JObject obj = JObject.Parse(responseJson);

        JArray categories = (JArray)obj["d"]["results"];

        if (categories.Count == 0)
        {
            return default(T);
        }

        string JSON = categories.ToString();

        return JsonConvert.DeserializeObject<T>(JSON);
    }

The T is type of string, i just want to return the plain JSON data.

            //HttpClientWrapper
        using (var client = new HttpClientWrapper<string>())
        {
            var data = client.GET(_URL, null, null);
            return data.ToString();
        }

But when i put the JSON in the DeserializeObject i get following error message:

Additional information: Unexpected character encountered while parsing value: [. Path '', line 1, position 1.

When i return it as List it will work But just as type string it will give that eror.

If you want the plain JSON data, why do you call DeserializeObject?

It sounds like you want something like that:

...
string JSON = categories.ToString();

// exit early, if we want the plain JSON data
if (typeof(T) == typeof(string))
    return (T)(object)JSON;

return JsonConvert.DeserializeObject<T>(JSON);

The double cast (T)(object) is necessary, since we know that T is of type string, but the compiler doesn't.
