下面是code片： 加入System.IO和System.Net和System.Xml

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();
