How to Pass Argument as Object for call WCF DataContract

Question

l - This My Interface Class For WCFSeviceLibrary

In This interface class IService1 in declare OperationContract as one ObjectClass Type Method.

And Create this ObjectClass Class For Set Type. as Ganeric.

    public interface IService1
        {               
             [OperationContract]
             ObjectClass SetDataUsingDataContract(ObjectClass data); 
        }
    [DataContract]
        public class ObjectClass
        {
            string name;
            string address;
            string emailid;
            double contactno;
            [DataMember]
            public string Name
            {
                set { name = value; }
                get { return name; }
            }

            [DataMember]
            public string Address
            {
                set { address = value; }
                get { return address; }
            }

            [DataMember]
            public string EmailId
            {
                set { emailid = value; }
                get { return emailid; }
            }

            [DataMember]
            public double ContactNO
            {
                set { contactno = value; }
                get { return contactno; }
            }

        }

Service.cs File In This Class Implimate

public class Service1 : IService1
    {
 public ObjectClass SetDataUsingDataContract(ObjectClass data)
        {

            SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=D:\Pavan\WCF_Practice\WcfServiceSample\WebApplicationvc\App_Data\WCFDB.mdf;Integrated Security=True;User Instance=True");
            conn.Open();
            SqlCommand cmd = new SqlCommand("INSERT INTO WCFTBL (Name, Address, ContactNo, EmailID) VALUES ('"+data.Name+"','"+data.Address+"','"+data.ContactNO+"','"+data.EmailId+"')",conn);
            cmd.ExecuteNonQuery();
            conn.Close();
            return data;
        }
}

This My Btn_Click Class of WebApplication Page

 protected void Add_Click(object sender, EventArgs e)
        {
            ServiceReference1.Service1Client srv = new ServiceReference1.Service1Client();


            srv.SetDataUsingDataContract();

}

I Dont Know How To Set Argument Of srv.SetDataUsingDataContract() method.

Answer 1

Create an ObjectClass instance and pass it as an argument to SetDataUsingDataContract. For example:

protected void Add_Click(object sender, EventArgs e)
{
     ServiceReference1.Service1Client srv = new ServiceReference1.Service1Client();

     ObjectClass objectClass = new ObjectClass();
     // Set properties 
     srv.SetDataUsingDataContract(objectClass);
}

The client generation code should have created an ObjectClass class for the caller to reference.
