Question

I need to implement a system that has the ability to conditionally consume web services on different disparate applications which are deployed with the same WSDL.

For e.g., If System B, C, D and E host webservices WS1, WS2, WS3 and WS4 which are all based on the same WSDL thereby exposing the same web methods, then my system A would require to consume one of these 4 webservices based on a condition retrieved from a downstream component (e.g., the database). The systems B, C, D and E can be implemented in any technology (Java, .NET, etc..) but my system A is based on .NET.

So the proxy class based on this WSDL on my system A would need to dynamically change the URI in the webservice proxy. So how do I dynamically change the endpoint before I consume the required webservice?

Answer 1

The proxy class generated by “Add Service Reference” or svcutil.exe has several constructors that accept a remote address. Use one of those. See WCF Client Overview.

For instance:

EndpointAddress addr = new EndpointAddress(uri);
var client = new MyServiceClient(bindingConfigurationName, addr);
