WCF DataContract Inheritance

First we create WCF service application,

Iservice File Code :-

[ServiceContract]

    public interface IService1

    {

        [OperationContract]

        string GetData(clsCustomer2 objcustomer);        

    }

    

    [DataContract]  

    public class clsCustomer1

    {

        [DataMember]

        public string firstname { get; set; }



        [DataMember]

        public string lastname { get; set; }         

    }



    [DataContract]

    public class clsCustomer2: clsCustomer1

    {

        [DataMember]

        public string salary { get; set; }

    }

Then we write the implementation of the interface in the service class.
Service file code:-

public class Service1 : IService1

    {

        public string GetData(clsCustomer2 objcustomer)

        {

            return objcustomer.firstname + "---" + objcustomer.lastname + "---" + objcustomer.salary;

        }

    }

Then I created a console client and tested the service. I added a service reference of the above service and created a proxy class.
Client code :-

class Program

    {

        static void Main(string[] args)

        {

            Service1Client objClient = new Service1Client();



            clsCustomer2 objc = new clsCustomer2();

            objc.firstname = "Akiii";

            objc.lastname = "lethal";

            objc.salary = "10";



            string str = objClient.GetData(objc);



            Console.WriteLine(str);

            Console.ReadLine();

        }

    }

Try this and if you find any problem in the above code, please let me know !


Thanks and Regards
