message contract in wcf

using
System;

using
System.Collections.Generic;

using
System.Linq;

using
System.Runtime.Serialization;

using
System.ServiceModel;

using
System.Text;

namespace
Wcfm
{// NOTE: If you change the interface name "IService1" here, you must also update the reference to "IService1" in Web.config.

[serviceContract]
public interface IService1
{
[OperationContract]
EmployeeDetails getEmployeeDetails(); 
// TODO: Add your service operations here

}}
------------------------------------------------------------------------------------------------------------
now implement interface,

using
System;

using
System.Collections.Generic;

using
System.Linq;

using
System.Runtime.Serialization;

using
System.ServiceModel;

using
System.Text;

namespace
Wcfm

{// NOTE: If you change the class name "Service1" here, you must also update the reference to "Service1" in Web.config and in the associated .svc file.

public class Service1 : IService1
{public EmployeeDetails getEmployeeDetails()
{EmployeeDetails obj = new EmployeeDetails();
obj.Designation = "Manager";
obj.EmpID = 101;
obj.EmpName = "Mukesh";
obj.Location = "Noida";
obj.Salary = 50000;return obj;

}

}
}
----------------------------------------------------------------------------------------------------------------------------------------
now take class1 and do the following code


using
System;

using
System.Collections.Generic;

using
System.Linq;

using
System.Web;

using
System.ServiceModel;

using
System.Runtime.Serialization;



namespace
Wcfm

{

[MessageContract]
public class EmployeeDetails

{
[MessageHeader]
public int EmpID;
[
MessageBodyMember]
public string EmpName;

[MessageBodyMember]
public string Designation;

[MessageBodyMember]
public int Salary;
[MessageBodyMember]
public string Location;

}

}
and now run service and consume it...
