Calling WCF Service with Service Reference

Doğru Kullanım

ServiceReference1.ArdTarifeServiceClient obj = new ServiceReference1.ArdTarifeServiceClient();

                    using (obj)

                    {

                        string s = (obj.Increment().ToString());

                    }

Daha Doğru Kullanım

bool mSuccess = false;

            ServiceReference1.ArdTarifeServiceClient obj = new ServiceReference1.ArdTarifeServiceClient();

            try

            {

                string s = obj.Increment().ToString();

                obj.Close();

                mSuccess = true;

            }

            finally

            {

                if (!mSuccess)

                    obj.Abort();

            }
