Start this article:

1, the creation of asp.net MVC procedures, as the call WebService client (using WebForm, WinForm the same reason);

2, add a controller, named GetWeather

3, add "service Reference", to find the service set a namespace, I used here is Servicereferenceweather

4, the above can be seen after completion

5, open the controller, add the following code

        Public ActionResult GetWeather ()
        {return
            View ();
        }

        [HttpPost]
        Public ActionResult GetWeather (formcollection formcollection)
        {
            string cityname = formcollection[" Txtcityname "];
            Servicereferenceweather.weatherwebservicesoapclient w = new Weatherwebservicesoapclient ("WeatherWebServiceSoap");
            string[] res = new STRING[23];
            res = W.getweatherbycityname (cityname);
            viewdata.model= Res;
            return View ();
        }

6, add a view for the GetWeather controller, I use the Razor template engine, with ASPX is the same

7, the default view of the code to replace the following code (in fact, some HTML and CSS, you can write yourself)

@{Layout = null;} <! DOCTYPE html>  
8. Change the default route of ASP.net MVC to controller and action for this case
