// example of web service

public class Service1 : IService1

 {

        public string GetData( int value )

        {

            return string.Format( "You entered: {0}", value );

//example in controller



public ActionResult Index()

        SettingsModel config = null;



        // Set up a channel factory to use the webHTTPBinding

        using (WebChannelFactory serviceChannel =

            new WebChannelFactory(new Uri(baseServiceUrl )))

        {

            IChangeService channel = serviceChannel.CreateChannel();

            config = channel.GetSysConfig();

        }



        ViewBag.Message = "Service Configuration";



        return View(config);
