calling a web service method in WCF layer

Question

HI,
I am trying to implement a WCF layer, in which I must make a call to a web service (service1)

exactly, I must make a call to a method (consultationClient ())FROM this web service which should show the list of clients which corresponds to the identifier entered (in our case ID_CLIENT).

when I test this method in the web service , the consultation goes well, but when I'm calling this method in the WCF layer customer_id and I tapped the ID_CLIENT, it show me a list containing 10 clients with its ID_CLIENT = 0 and all other fields of the client are 0 or null according to their types,


Here is the code containing the method call consultationClient () in the layer WCF


Code:
public List ConsultationClientWCF (int ID_CLIENT)
{

Service1 service = new Service1 ();
ClientTopNet ClientTopNet CL = new ClientTopNet ();

List test = ser.ConsultationClient (CL.ID_CLIENT);
return test;




}


knowing that I am a beginner.


Please help me
