Need help with a web service

Hi,

I've just started learning to create/consume web services using VS2005 and C#. I've written a program that consumes this service:http://www.webservicex.net/CurrencyConvertor.asmx

Code:

namespace SOAPDemo
{
    class MyService
    {
        static void Main(string[] args)
        {

            ConvertorService.CurrencyConvertor _Service = 
                new ConvertorService.CurrencyConvertor();

            String s1 = "USD";
            String s2 = "QAR";

            double rate = _Service.ConversionRate(
                SOAPDemo.ConvertorService.Currency.USD,
                SOAPDemo.ConvertorService.Currency.QAR); 

            Console.WriteLine( "The current rate is : " + rate );
            Console.ReadKey();

        }
    }
}

As you can see the remote method "ConversionRate" only accepts parameters of type "ConvertorService.Currency.xxx". But I want to take the parameters as inputs from the user which will be stored in the form of strings. So how can I pass them to the method??

This is my first program and I'm really new to this.

Any sorta help wud be gr8ly appreciated.

Hi,

as you noticed already, you need some way to convert from the userinput-type (string), to the webservices' Currency-type (an enumeration to be precise).

For this, you can use the Parse-method of the Enum-type

ps: also note the line "using CurrencyConvertorWebServiceDemo.ConvertorService;" so you don't need to explicitly name the namespace throughout your code all the time.

hth,
michaÃÂ«l

using System;
using CurrencyConvertorWebServiceDemo.ConvertorService;

namespace CurrencyConvertorWebServiceDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            CurrencyConvertor _Service = new CurrencyConvertor();

            String s1 = "USD";
            String s2 = "QAR";

            Currency fromCurrency = String2Currency(s1);
            Currency toCurrency = String2Currency(s2);

            double rate = _Service.ConversionRate(fromCurrency, toCurrency);

            Console.WriteLine("The current rate is : " + rate);
            Console.ReadKey();
        }

        private static Currency String2Currency(string currency)
        {
            return (Currency) Enum.Parse(typeof(Currency), currency, true);
        }
    }
}
