How to programmatically connect a client to a WCF service?

Question

I'm trying to connect an application (the client) to an exposed WCF service, but not through the application configuration file, but in code.

How should I go about doing this?

Answer 1

You'll have to use the ChannelFactory class.

Here's an example:

var myBinding = new BasicHttpBinding(); var myEndpoint = new EndpointAddress("http://localhost/myservice"); using (var myChannelFactory = new ChannelFactory<IMyService>(myBinding, myEndpoint)) {     IMyService client = null;      try     {         client = myChannelFactory.CreateChannel();         client.MyServiceOperation();         ((ICommunicationObject)client).Close();         myChannelFactory.Close();     }     catch     {         (client as ICommunicationObject)?.Abort();     } }

You can also do what the "Service Reference" generated code does

public class ServiceXClient : ClientBase<IServiceX>, IServiceX {     public ServiceXClient() { }      public ServiceXClient(string endpointConfigurationName) :         base(endpointConfigurationName) { }      public ServiceXClient(string endpointConfigurationName, string remoteAddress) :         base(endpointConfigurationName, remoteAddress) { }      public ServiceXClient(string endpointConfigurationName, EndpointAddress remoteAddress) :         base(endpointConfigurationName, remoteAddress) { }      public ServiceXClient(Binding binding, EndpointAddress remoteAddress) :         base(binding, remoteAddress) { }      public bool ServiceXWork(string data, string otherParam)     {         return base.Channel.ServiceXWork(data, otherParam);     } } 

Where IServiceX is your WCF Service Contract

Then your client code:

var client = new ServiceXClient(new WSHttpBinding(SecurityMode.None), new EndpointAddress("http://localhost:911")); client.ServiceXWork("data param", "otherParam param");
