How to solve this web service issue?

Hi,

 

 I have a WSDL service (see attached extracted file from WSDL).That used for currency converter.

Here is my code 

 

CurrencyWebRef.CurrencyService obj = new CurrencyWebRef.CurrencyService();
CurrencyWebRef.Currency Currency = new CurrencyWebRef.Currency();
double dt = new double();
Response.Write(obj.GetConversionRate(CurrencyCode.AED, true, CurrencyCode.ANG, true)); 

 

I have a problem with this conversion and I will get the result as "Currency" instead of the real

conversion rate.Surely I have made some mistake in my code.Can anyone help me out.

 

I have a doubt with highlighted part.

Thanks
