C# Code

public string CurrencyConversion(decimal amount, string fromCurrency, string toCurrency)
       {
           WebClient web = new WebClient();
           string url = string.Format("https://www.google.com/finance/converter?from={0}&to={1}&a={2}", fromCurrency.ToUpper(), toCurrency.ToUpper(), amount);
           string response = web.DownloadString(url);
           Regex regex = new Regex("<span class=bld>(.*?)</span>");

           var result = regex.Match(response).Groups[1].Value;
           return result;
       }

           returnList.Columns.Add("rate", typeof(decimal));
           Thread.CurrentThread.CurrentCulture = new CultureInfo("en-US");
           string date = string.Empty;
           using (XmlReader xmlr = XmlReader.Create(@"https://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml"))

               xmlr.ReadToFollowing("Cube");
               while (xmlr.Read())
               {
                   if (xmlr.NodeType != XmlNodeType.Element) continue;
                   if (xmlr.GetAttribute("time") != null)
                   {
                       date = xmlr.GetAttribute("time");
