Call WCF method from client c# -

i have created 1 wcf service application. there few methods in service1.svc.

here iservice1.cs

[operationcontract] getuserdetailsbyemail_result getuserdetailsbyemail(string email); 

here service.svc.cs

public class service1 : iservice1 {     #region getuserdetails     public getuserdetailsbyemail_result getuserdetailsbyemail(string email)     {         return (new usermanager()).getuserdetailsbyemail(email);     }     #endregion     } 

here getuserdetailsbyemail_result complex type created in demomodel.edmx. contain scalar property.

basically trying is, want call method client(c#) side. here client side code

//svc.getuserdetailsbyemailcompleted += new eventhandler<getuserdetailsbyemailcompletedeventargs>(svc_getuserdetailsbyemailcompleted); getuserdetailsbyemail_result dtbuserdetails = svc.getuserdetailsbyemailasync(loginname); 

here svc object of service1client. here calling wcf method. gives me error

cannot implicitly convert type 'void' 'demo.demoservicereference_client.getuserdetailsbyemail_result'

it works when use svc_getuserdetailsbyemailcompleted method. want return data directly in dtbuserdetails. how can achieve this? there changes in wcf service or in client side? or in wcf method declaration?

you either need create object , bind data of people in comments suggested mark each property so:

[datacontract(namespace = "myservicecontract.service1.complexobject")] public class complexobject {        [datamember(order = 1, isrequired = true)]             public string dbitem1{ get; private set; }        [datamember(order = 2, isrequired = false)]             public complexblobdata dbitem2{ get; set; } } 

or if can open demomodel.edmx(code behind) , mark data contract same way mark own object.

bottom line not marked not going on wire.
