Question

My client is using proxy created from WSDL… Is it possible to setup the service to send List instead of MyCustomObject[]?

I am using

svcutil /t:metadata /ct:System.Collections.Generic.List`1 localhost:8080/managedApp 

but does not work…

My client are in Visual C++

IDE is Visual Studio 2012 –> cannot add service reference

Ok… at the end I gave up, I just sent the data as array instead of std:list…

this is how I did it:
1.- get the metadata from the service using svcutil /t:metadata (NOTE: service has to be running).
2.- create the proxy wsutil *.wsdl *.xsd
3.- add proxy files (.h and .c) to my client and use the proxy functions to the service.

Array are a little bit tricky if you are not familiar with c programming though…

DataContract:

    [DataContract]
        public class CompositeType
        {
            CompositeType2[] ctListValue;
            bool boolValue;
            string stringValue;

            [DataMember]
            public bool BoolValue
            {
                get { return boolValue; }
                set { boolValue = value; }
            }

            [DataMember]
            public string StringValue
            {
                get { return stringValue; }
                set { stringValue = value; }
            }

            [DataMember]
            public CompositeType2[] CtListValue
            {
                get { return ctListValue; }
                set { ctListValue = value; }
            }
        }

        [DataContract]
        public class CompositeType2
        {
            bool boolValue;
            string stringValue;

            [DataMember]
            public bool BoolValue
            {
                get { return boolValue; }
                set { boolValue = value; }
            }

            [DataMember]
            public string StringValue
            {
                get { return stringValue; }
                set { stringValue = value; }
            }
        }

and my client side for the calls to array:

// *** COMPOSITETYPE CALL
    CompositeType * co = new CompositeType();
    co->BoolValue = true;
    co->StringValue = L"Im co";

    CompositeType2 co0;
    co0.BoolValue = true;
    co0.StringValue = L"Im co0";

    CompositeType2 co1;
    co1.BoolValue = true;
    co1.StringValue = L"Im co1";

    CompositeType2 co2;
    co2.BoolValue = true;
    co2.StringValue = L"Im co2";

    CompositeType2 ** comType2; // <-- this is my CompositeType2[] I will send to the service
    comType2 = new CompositeType2*[3];

    comType2[0] = &co0;
    comType2[1] = &co1;
    comType2[2] = &co2;

    co->CtListValue = comType2;
    co->CtListValueCount = 3;

    CompositeType* result2;

    BasicHttpBinding_IHelloWorldService_SayHelloCompType(
            proxy, co, &result2,
            heap, NULL, 0, NULL, error);

Hope this helps…
