Error : Cannot convert type 'string' to 'net.webservicex.www.Currency' .

error comes from:

net.webservicex.www.CurrencyConvertor conver = new net.webservicex.www.CurrencyConvertor();

double d = conver.ConversionRate((Currency)ddfr.SelectedValue,(Currency)ddto.SelectedValue);

ddfr and ddto are dropdownlist.

Accepted answer
try this.

CurrencyConvertor conver = new CurrencyConvertor();
Currency From = (Currency) Enum.Parse(typeof(Currency), ddfr.SelectedValue.ToString(),true);
Currency To = (Currency)Enum.Parse(typeof(Currency), ddto.SelectedValue.ToString(), true);
double d = conver.ConversionRate(From, To);

Judging by an example I found on the Internet, you'll have to do something like this (extend the switch statements as necessary):

net.webservicex.www.Currency obj = new net.webservicex.www.Currency();

switch(ddfr.SelectedValue.ToString())
{

case "SGD":

obj = net.webservicex.www.Currency.SGD;

break;

case "USD":

obj = net.webservicex.www.Currency.USD;

break;

case "AUD":

obj = net.webservicex.www.Currency.AUD;

break;

case "EUR":

obj = net.webservicex.www.Currency.EUR;

break;

case "INR":

obj = net.webservicex.www.Currency.INR;

break;

}

net.webservicex.www.Currency obj2 = new net.webservicex.www.Currency();

switch(ddto.SelectedValue.ToString())
{

case "SGD":

obj2 = net.webservicex.www.Currency.SGD;

break;

case "USD":

obj2 = net.webservicex.www.Currency.USD;

break;

case "AUD":

obj2 = net.webservicex.www.Currency.AUD;

break;

case "EUR":

obj2 = net.webservicex.www.Currency.EUR;

break;

case "INR":

obj2 = net.webservicex.www.Currency.INR;

break;

}

net.webservicex.www.CurrencyConvertor conver = new net.webservicex.www.CurrencyConvertor();

double d = conver.ConversionRate(obj, obj2);
