What is "normal Web service", why "don't suggest it"? What do you need for a source of exchange rates? This is not even a question...

coz i got the webservices such as http://fx-rate.net ( http://fx-rate.net/converter.php?) and it was not as i need. My need is specified well in my query.ie price list in mysite should be in default USD and by users click as there neede currency.

What's the logic! You faces some, let's trust you, inadequate services and made a conclusion that Web services is not good for you. Your specified need is gibberish. Don't you think a Web service is something which would present the data in exact form you keep in mind?

Google's[^] seems like it would work - you'll have to parse the output

You can change value of input currency, for example you want to know the value for $100 in India Rupees

pardon i need to check it in server side itself. Ie While the user select currecy from the dropdownlist, the result should appearin dropdownlist selected index changed

Why do you always mix the service which works purely with data with presentation/control using the UI? The approach is different: informational part is on the service, UI is on you. You need loose coupling of them.

It's good that you agree that the way to go is to use appropriate Web services. Please read about consuming the Web services (consuming is all you need) here:

Created a web service its code:

C++

WebClient web = new WebClient();
        string url = string.Format("http://www.google.com/ig/calculator?hl=en&q={2}{0}%3D%3F{1}", fromCurrency.ToUpper(), toCurrency.ToUpper(), amount);
        string response = web.DownloadString(url);
        Regex regex = new Regex("rhs: \\\"(\\d*.\\d*)");
        decimal rate = System.Convert.ToDecimal(regex.Match(response).Groups[1].Value);
        return rate;

this was called to my web page.keeping USD as default and to currency selecting from a dropdownlist. And the result displayed in a label, its c# code is

C++

localhost.WebService ws = new localhost.WebService();
        decimal amount = Convert.ToDecimal(LabelFromCurrency .Text );
        string fm = "USD";
        string tt = DropDownList1.SelectedValue.ToString();
        decimal result;
        result = amount * ws.Convert(1, fm, tt);
        LabelToCurrency.Text = "Result is: " + result.ToString();

create two text box ,a lable and one button

XML

<asp:Label ID="Label1" runat="server" Text=""></asp:Label><br /><br />
               <tr>
               <td>
                           Enter Purchase Currency Code:
               </td>
               <td>
               <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />

               </td>
               </tr>
               <tr>
               <td>
                Enter Reciever Currency Code
               </td>
               <td>
                <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
               </td>
               </tr>


       </table>

use this name space

C#

using System.IO;
using System.Net;
using System.Xml;

in search button click add this code

protected void btnSearch_Click(object sender, ImageClickEventArgs e)
    {
        try
        {
            string xmlResult = null;
            string url;
            url = "http://www.webservicex.net/CurrencyConvertor.asmx/ConversionRate?FromCurrency=" + TextBox1.Text + "&ToCurrency=" + TextBox2.Text + "";
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            StreamReader resStream = new StreamReader(response.GetResponseStream());
            XmlDocument doc = new XmlDocument();
            xmlResult = resStream.ReadToEnd();
            doc.LoadXml(xmlResult);
            Label1.Text = "Current Exchange Rate for " + TextBox1.Text.ToUpper() + " ---> " + TextBox2.Text.ToUpper() + " value " + doc.GetElementsByTagName("double").Item(0).InnerText;
        }
        catch (Exception ex)
        {
            Label1.Text = "Not a valid Currency or Try again later";
        }
