我正在开发一个Windows应用程序，以美元转换为INR。我知道如何通过采取美元以静态的方式INR汇率转换，但我想汇率动态可在我只读文本框就像我一直在上面的图片。

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.

SO上搜索后，我发现这个解决方案中的C，但我想在C＃中的相同。我的目标是动态的，每天从网络上获取美元，以印度卢比汇率在我只读文本框。

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.

我应该使用哪种方法上面提到得向美元INR汇率动态？

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

推荐答案

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();
        response.Close();
