My purpose is:

run a self-hosting WCF service, whose base address is set at runtime according to the available network card/s; clients discover the service and get the address.

Previous answers:

I have found the same purpose and a suggested solution here

My problem:

When I run the hosting console app an exception is thrown here:

var host = new ServiceHost(typeof(WcfPingTest), new Uri("http://*:7400/WcfPing"));

Exception details: System.UriFormatException: Invalid URI: The hostname could not be parsed

If I replace * with localhost, it works, but it does not satisfy my task, that is: get the real ip address from the client, and not the hard-coded one.

I have tried also to do it inside the app.config file, but the exception is the same:

Where did I go wrong?

Additional info: C# code, .NET Framework 4.5

UPDATE: Wildcard usage works using in app.config file:

<baseAddresses><add baseAddress="http://*:7400/WcfPing" /></baseAddresses>

and in console app: 

var host = new ServiceHost(typeof(WcfPingTest))

On the other hand, Uri constructor does not accept a uriString parameter with the * char inside

NEXT TOPIC: with the above source code, my clients get the uri at runtime, but this uri contains the MY_COMPUTER_NAME like http://MY_COMPUTER_NAME:7400/WcfPing, intead of 

http://MY_IP_ADDRESS:7400/WcfPing

Is there any method to get the actual IP address? (I have multiple NICs for different local networks)

The exception was appeared because the uriString is invalid for Uri. About wildcard in the config file, please check that your config file is similar

<system.serviceModel>
    <services>
        <service name="Nelibur.ServiceModel.Services.JsonServicePerCall">
            <host>
                <baseAddresses>
                    <add baseAddress="http://*:9095/feedback" />
                </baseAddresses>
            </host>
            <endpoint binding="webHttpBinding"
                      contract="Nelibur.ServiceModel.Contracts.IJsonService" />
        </service>
    </services>
</system.serviceModel>

and new ServiceHost doesn't contain new Uri, maybe you just forgot about it

var host = new ServiceHost(typeof(WcfPingTest)

  • You are right. Using `` in config file and `var h = new ServiceHost(typeof(WcfPingTest.WcfPingTest))` works! However `var host = new ServiceHost(typeof(WcfPingTest), new Uri("http://*:9095/feedback"))` does not work. Probably uriString does not allow wildcard. With the above code my clients get: the `http://MY_COMPUTER_NAME:9095/feedback` and not the actual ip address like `http://MY_NIC_IP_ADDRESS:9095/feedback` – pimo Apr 03 '14 at 13:17
