Abstract: In this article I will guide you through the process of creating simple currency converter using Foxrate.com XML RPC API. This API is free to use. There a few examples available in programming languages such as Python, PHP or RoR, however in ASP.NET C# its the first.
What we need: In order to connect to the XML-RPC API, you will need an XML-RPC client. First of all add latest version of “CookComputing.XmlRpc” to your project. I have used ver 2.5 in my project, since it has some bug fixed related to permission and security when running on live server.
Source: XML-RPC client DLL download link: http://xmlrpcnet.googlecode.com/files/xml-rpc.net.2.5.0.zip
References: Add following references in your code behind files:
Now, the code behind activity by defining endpoint and creating an Interface.
public interface IXchangeRate
double amount); // Please note that Foxrate.org RPC accepts “Float” data type however, CookComputing.XmlRpc does not provide support for “Float”, thus we use double instead.
public void GetRates(string strTo, string strFrom, double dAmount)
IXchangeRate proxy = (IXchangeRate)XmlRpcProxyGen.Create(typeof(IXchangeRate));
MyStruct = proxy.GetXchangerate(strTo, strFrom, dAmount);
foreach (DictionaryEntry d in MyStruct)
Response.Write(d.Key + ” : ” + d.Value);
Finally call the function as under:
GetRates(“INR”, “USD”, “10.0”);
