  public static  Signup_Root Check_xsignup(Register register)
    {
        HttpResponseMessage result = null;
        string resultt = "";
        Signup_Root lp =null;
        try
        {
            string jObj = JsonConvert.SerializeObject(register);
            StringContent content = new StringContent(jObj, System.Text.Encoding.UTF8);
            MediaTypeHeaderValue mValue = new MediaTypeHeaderValue("application/json");
            content.Headers.ContentType = mValue;
            string url = Constant.url + "api/services/app/Account/Register";
            HttpClient _client = new HttpClient();
            result =  _client.PostAsync(url, content).Result;
            if (result.StatusCode == HttpStatusCode.OK)
            {
                resultt = result.Content.ReadAsStringAsync().Result;
                lp = JsonConvert.DeserializeObject<Signup_Root>(resultt);
            }
        }
        catch (Java.Lang.Exception ex)
        {

        }
        return lp;
    }

Try this, It will work
