Question

I’m developing a Windows application to convert USD to INR. I know how to convert by taking USD to INR exchange rate in static way, but I want the exchange rate to be available dynamically in my readonly textbox like I have kept in above image.

After searching on SO I found this solution in C but I want to do the same in C#. My aim is to get the USD to INR exchange rate in my readonly textbox dynamically each day from the web.

Which method should I use in above reference to get USD to INR exchange rate dynamically?

Answer 1

Here is the code piece:
Add System.IO and System.Net and System.Xml

WebRequest webrequest =WebRequest.Create("http://www.webservicex.net/CurrencyConvertor.asmx/ConversionRate?FromCurrency=USD&ToCurrency=INR");
        HttpWebResponse response = (HttpWebResponse)webrequest.GetResponse();
        Stream dataStream = response.GetResponseStream();
        StreamReader reader = new StreamReader(dataStream);
        string responseFromServer = reader.ReadToEnd();
        XmlDocument doc = new XmlDocument();
        doc.LoadXml(responseFromServer);
        string value = doc.InnerText;
        MessageBox.Show(value);
        reader.Close();
        dataStream.Close();
        response.Close();
