WebClient is giving exception

Question

Hi,

 

WebClient is giving exception. It is not able to get the data in ResultInCSV. 

try
            {
                string ServiceURL = $"http://finance.yahoo.com/d/quotes.csv?s={symbol}&f=sl1d1nd";
                string ResultInCSV;
                using (WebClient client = new WebClient())
                {
                    ResultInCSV = await client.DownloadStringTaskAsync(ServiceURL).ConfigureAwait(false);
                }
                var FirstLine = ResultInCSV.Split('\n')[0];
                var Price = FirstLine.Split(',')[1];
                if (Price != null && Price.Length >= 0)
                {
                    double result;
                    if (double.TryParse(Price, out result))
                    {
                        return result;
                    }
                }
                return null;
            }
            catch (WebException ex)
            {
                throw ex.InnerException;
            }
        }

 Please help to get the data.

 

Thanks,
