Calling web Service, from one error to another "Proxy Access Denied" into "The underlying connection was closed"

[lpinho]

Hi There,

I've generated a C# file from a wsdl file using wsdl.exe utility.
Then I created a console application and made a call to the method
generated, first I got the error:

"The request failed with HTTP status 407: Proxy Access Denied."

Then I added a proxy validating and proxy credentials and got this:

"The underlying connection was closed: An unexpected error occurred on
a receive."

I send you the code to see if you can help me on this one, please...

Thanks,

Luis Miguel Pinho
