Hi,

I need to display current exchange rates on my application.
Is it possible to retrieve the exchange rate from http://www.xe.com (XE Converter)
Thank you.
Here what I tried:
public string CurrencyConversion(decimal amount, string fromCurrency, string toCurrency)
        {
            string Output = "";
             string fromCurrency1 = comboBox1.Text;
             string toCurrency1 = comboBox2.Text;
             decimal amount1 = Convert.ToDecimal(textBox1.Text);

            // For other currency symbols see http://finance.yahoo.com/currency-converter/
            // Construct URL to query the Yahoo! Finance API

            const string urlPattern = "http://finance.yahoo.com/d/quotes.csv?s={0}{1}=X&f=l1";
            string url = string.Format(urlPattern, fromCurrency1, toCurrency1);

            // Get response as string
            string response = new WebClient().DownloadString(url);

            // Convert string to number
            decimal exchangeRate =
                decimal.Parse(response, System.Globalization.CultureInfo.InvariantCulture);

            // Output the result
            Output = (amount1 * exchangeRate).ToString();
            textBox2.Text = Output;

            return Output;
        }
With this code I am not having the full output... the decimal part is not showing...
