Separate web service environments

Hi,

I'm new to WCF, and so I would like to ask for some guidelines in designing a web service client.

The target web service has four different environments - system test, integration test, acceptance test and production. The API is exactly the same for all different environments. The user of my application should be able to select what environment to use. In my VS project I have added a service reference to all four environment WSDL:s.

To the question. Since all environments use the same API but with different endpoints, is there any way I can switch between the endpoints in the actual web service call? I don't want to write four different methods for this(building the soap request is a lot of code...).

//Declare the service envelope
SYS_TEST.ServiceEnvelope serviceEnvelope = new ServiceEnvelope ();
serviceEnvelope.Password = "xxx"
//lots of code filling up the request goes here...
SYS_TEST.CalculateXXClient client = new CalculateXXClient();
//Send the request
client.calculateXX(ref serviceEnvelope);
