Consume WebService in C#

[joelcochran]

I am trying to consume my first WebService in a C# Windows Form in
VS.NET 2003. I have created a Web Reference using the WSDL URL
(http://www.capescience.com/webservic...tWeather.wsdl),
which created the Proxy class. I can see the WebService and its
methods in the Object Browser.

It was my impression that I should be able to simply instantiate the
webservice now and use its methods, so I have the following code:

<code>
CallWebService.com.capescience.www.AirportWeather weather =
new CallWebService.com.capescience.www.AirportWeather();
string summary = weather.getSummary( "KLAX" ).ToString();
</code>

When I run this, I get a 404 not found message. Out of curiosity, I
added a call to ".Discover":

<code>
CallWebService.com.capescience.www.AirportWeather weather =
new CallWebService.com.capescience.www.AirportWeather();
weather.Discover();
string summary = weather.getSummary( "KLAX" ).ToString();
</code>

Now when I run it, I receive a System.Net.WebException "there was an
error downloading 'http://www.capescience.com/ccgw/GWXmlServlet'."

I hate to sound foolish, but does this mean the WebService is not
available? I thought it might be a proxy issue, so I created an
App.config file and added a defaultProxy bypass (found in the
newsgroup) but it made no difference.

Why would I be able to see the Classes and Methods in the Object
Browser but not be able to call it? Does anyone know of a WebService I
can use to test with?

Thanks,

Joel

I think I've answered my own question. The web service must not be
available. I found this article:

http://www.scientificfinance.com/pap...BestMonths.asp

I followed the exact same steps:
1) Add Web Reference (to the new web service)
2) Create Object and use methods

Simple as pie and this time it worked lickity split, no messing with
proxies or anything like that. Eventually, I'll use this approach in a
commercial application, so should I leave the "App.config" settings in
place? Will this help if the user is behind a firewall? I'm not a
network guy, so any advice would be appreciated.

Thanks,

Joel
