Question

am trying to create WCF client to consume the service, which contains messages.
So far I am trying to communicate with by messages, that are made of an header (DateTime) and the body which is an object called User.
I have imported the app.config and the Proxy by using svcutil.
But, I get few errors.
Code:

    {
        RegistryServiceClient client = new RegistryServiceClient("WSHttpBinding_IRegistryService");
        UserMessage message = new UserMessage();


        message.time = DateTime.Now;

        message.user.id = "1";
        message.user.firstname = "John";
        message.user.lastname = "Smith";

        client.RegisterUser(message.time, message);
    }

Errors:
Error 2 Argument 1 must be passed with the ‘ref’ keyword
Error 3 Argument 2: cannot convert from ‘UserMessage’ to ‘ref http://www.domain.co.uk.User.user’
Error 1 The best overloaded method match for ‘RegistryServiceClient.RegisterUser(ref System.DateTime, ref http://www.domain.co.uk.User.user)’ has some invalid arguments

Answer 1

The RegisterUser method signature specifies a different type than your UserMessage, specifically a type called http://www.domain.co.uk.User.user. I don’t know the specifics of the UserMessage class, but I’m going to go out on a limb and guess that the user property is of type http://www.domain.co.uk.User.user. So try:

client.RegisterUser(ref message.time, ref message.user)

and see what happens.
