c# - How to return my complex types from a wcf service, not model itself? -

i have separate layer complex types dataaccesslayer(dal), separate layer business businesslogiclayer(bl). create wcf service application project servicelayer(sl) , added service use bl methods , dal complex type return value.

now,i have 1 problem in add refrence myservice in mvc project , :

when added refrence of myservice, in refrence.cs generate complex type each mycomplex type used it.

i want not generate complex type , use of complex type @ dal.

dal

using system.runtime.serialization;  namespace dal {     [datacontract]     public partial class mycomplextype      {         //...          [datamember]         //my prop         //...     } } 

bl

namespace bl {     public partial class myrepository     {         public list<dal.mycomplextype> mymethod(int param1,int param2)          {             var parameters= new list<sqlparameter>();             parameters.add(new sqlparameter("param1",sqldbtype.int){ value = param1 });             parameters.add(new sqlparameter("param2",sqldbtype.int){ value = param2 });             var result = dal.runprocedure("myproc", parameters);             return result.converttolist<dal.mycomplextype>();         }     } } 

sl

namespace sl {     [servicecontract]     public interface imyservice     {         [operationcontract]         list<dal.mycomplextype> myservicemethod(int param1,int param2);     } }  namespace sl {     public class myservice : imyservice     {         public list<dal.mycomplextype> myservicemethod(int param1, int param2)          {             bl.myrepository bl = new bl.myrepository();             list<dal.mycomplextype> result = bl.mymethod(param1, param2);             return result;         }     } } 

refrence.cs class in mymvcproject after added myservice refrence service :

//------------------------------------------------------------------------------ // <auto-generated> //     code generated tool. //     runtime version:4.0.30319.34014 // //     changes file may cause incorrect behavior , lost if //     code regenerated. // </auto-generated> //------------------------------------------------------------------------------  namespace mymvcproject.myservice {     using system.data;      [system.codedom.compiler.generatedcodeattribute("system.servicemodel", "4.0.0.0")]     [system.servicemodel.servicecontractattribute(configurationname = "myservice.imyservice")]     public interface imyservice     {         [system.servicemodel.operationcontractattribute(action = "http://tempuri.org/imyservice/myservicemethod", replyaction = "http://tempuri.org/imyservice/myservicemethodresponse")]         [system.servicemodel.xmlserializerformatattribute(supportfaults=true)]         mymvcproject.myservice.myservicemethodresponse myservicemethod(mymvcproject.myservice.myservicemethodrequest request);          // codegen: generating message contract since operation has multiple return values.

return type of used service refrence mthod mymvcproject.myservice.mycomplextype

mymvcproject.myservice.myserviceclient service = new mymvcproject.myservice.myserviceclient();  mymvcproject.myservice.mycomplextype result = service.myservicemethod(10,12); 

insted of :

dal.mycomplextype result = service.myservicemethod(10,12); 

how resolved it? problem?

my vs version 2013.

i test method in wpf project , result ok,that means service not create self complex type , use dal complex type.

but in mvc project both cheked , unchecked reuse types in refrenced assemblies in service configuration service create self complex types.

i not know how resolve problem or reason ?

i think doesn't works that, specially when adding service reference. remember doesn't reference actual dll in client once adding service reference.

upon serializing datacontract re-create own classes serializer can recognize , matter adding namespaces , upon deserializing in service check namespace identity equivalent object/class in actual object in service:

[system.xml.serialization.xmltypeattribute(namespace="http://schemas.datacontract.org/2004/07/dal")]     public partial class mycomplextype : object {        . . .      } 

if want use own dal in client why don't create client proxy or channelfactory programmatically , physically add dal.

take @ links on how create proxy programmatically:

• create wcf client without auto generated proxy
