How do you dynamically switch WCF Web Service Reference URL path through config file ?
Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.
Are you just wanting to override the URL that is in the config to a different url. Say you have a test service and a live service. You can just do this.
client.Endpoint.Address = new EndpointAddress(Server.IsLiveServer() ? @"LiveUrl" : @"TestURl");
Where those url come from wherever you want
Just to expand on the answer from Erin: –
MyClient client = new MyService.MyClient(); client.Endpoint.Address = new EndpointAddress(new Uri("insert new url here"), client.Endpoint.Address.Identity, client.Endpoint.Address.Headers); client.Open();
There is no dynamic switching. Each time you want to use another URL you must create new instance of service proxy (client) and pass EndpointAddress or enpoint configuration name to the constructor.
sure you can do this, have a look here: How to config clients for a wcf service?
it is absolutely normal to point to localhost in development and to change the address (url) in production in the web.config
you can´t chance endpoint url after any calling.
in that case, you will get answer from NEWURL:
MyClient client = new MyService.MyClient(); client.Endpoint.Address = new EndpointAddress("NEWURL"); client.Hello(); //return is hello response from NEWURL
but if you will call any method before changing url, the url will be used from app.config, like next example:
MyClient client = new MyService.MyClient(); client.Endpoint.Address = new EndpointAddress("NEWURL"); client.Hello(); //return is hello response from BASEURL
I have been trying to do the same thing but most of the accepted answers in various posts just change the address. Currently under .net 4.7, simply changing the address itself does not work. If you have two different servers and wanting it to switch from one to the other, you have to do this:
var client = new MyService.Service1Client(); var newAdrEndpoint = new EndpointAddress(new Uri("second server address")); client = new MyService.Service1Client(client.Endpoint.Binding, newAdrEndpoint);
Essentially you need to create a new service using the same binding from the first server and passing in the new address. This is the simplest method I have found.
