I'm trying to learn C#. This a first try with a simple web service.

I want to say:
rootNode = ws.getTemp(txtZIPCode.Text);

to consume the web service and get a temperature from a US ZIP Code. But I could not get the ws variable properly defined to connect to:
www.xmethods.com / TemperatureService.wsdl

I tried:
ws = new net.xmethods.www/TemperatureService.wsdl
but does not seem to work. I tried from VFP8 and the service works very well.

How do I write the ws = new definition?
