Learning Asp.net WebService (based on ASP.net MVC) through a weather forecast Case Study)

The data source of WebService: http://www.webxml.com.cn/WebServices/WeatherWebService.asmx

Start this article:

1. Create an Asp.net MVC program as the client that calls WebService (using webform and winform in the same way );

2. Add a controller named getweather.

3. Add "service reference" and set a namespace for the service. Here I use servicereferenceweather.

4. After completing the preceding steps, you can see

5. Open the controller and 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. The Razor template engine I use here is the same as Aspx.

7. Replace the default view code with the following code (in fact, some HTML and CSS, you can write them by yourself)

@ {Layout = NULL ;}<! Doctype HTML> 
8. Change the default route of Asp.net MVC to the Controller and action suitable for this case.


Press F5 to run the program. You can see:
