Consume Web Service in Windows Store App Using C#

<TextBlock x:Name="resultCityState" Height="100" HorizontalAlignment="Left" TextWrapping="Wrap" FontFamily="Verdana" Width="300" FontSize="36" Margin="15,400,0,0" />

</StackPanel>

<StackPanel Orientation="Vertical">

<TextBlock x:Name="resultDetails" HorizontalAlignment="Left" Height="365" Margin="30,400,0,-39" TextWrapping="Wrap" VerticalAlignment="Top" Width="704" FontFamily="Verdana" FontSize="25"/>

</StackPanel>

</Grid>

</Page>

Step 7 Then, you can call the service using the following task-based async model:

Here is the code of the XAML.cs file:

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using Windows.Foundation;

using Windows.Foundation.Collections;

using Windows.UI.Xaml;

using Windows.UI.Xaml.Controls;

using Windows.UI.Xaml.Controls.Primitives;

using Windows.UI.Xaml.Data;

using Windows.UI.Xaml.Input;

using Windows.UI.Xaml.Media;

using Windows.UI.Xaml.Navigation;

using App3.WeatherService;

// The Blank Page item template is documented at http://go.microsoft.com/fwlink/?LinkId=234238

namespace App3

{

/// <summary>

/// An empty page that can be used on its own or navigated to within a Frame.

/// </summary>

public sealed partial class MainPage : Page

{

public MainPage()

{

this.InitializeComponent();

}

/// <summary>

/// Invoked when this page is about to be displayed in a Frame.

/// </summary>

/// <param name="e">Event data that describes how this page was reached. The Parameter

/// property is typically used to configure the page.</param>

protected override void OnNavigatedTo(NavigationEventArgs e)

{

}

private async void GoButton_Click(object sender, RoutedEventArgs e)

{

WeatherSoapClient proxy = new WeatherSoapClient();

WeatherReturn result = await proxy.GetCityWeatherByZIPAsync(inputZipCode.Text);

ForecastReturn fr = await proxy.GetCityForecastByZIPAsync(inputZipCode.Text);

Forecast[] f = fr.ForecastResult;

if (result.Success)

{

resultCityState.Text = String.Format("{0}, {1}", result.City, result.State);

resultDetails.Text = String.Format

("\n\nConditions - {0} \n\nTemperature - {1} \n\nRelative Humidity - {2} \n\nWind - {3} \n\nPressure - {4} -
\n\nPressure - {5} - \n\nWind Chill - {6} - \n\nVisibility - {7}",

result.Description, result.Temperature, result.RelativeHumidity, result.Wind, result.Pressure, fr.WeatherStationCity, result.WindChill, result.Visibility);

}

GetWeatherInformationResponse result1 = await proxy.GetWeatherInformationAsync();

WeatherDescription[] r = result1.GetWeatherInformationResult;

foreach (WeatherDescription d in r)

if (d.WeatherID == result.WeatherID)

{

image i = new image();

i.imageurl = d.PictureURL;

myimage.DataContext = i;

break;

}

}

}

public class image

{

public string imageurl;

{

get;

set;

}

}

}

In the above code we are calling the weather web service and make the object the class and calling their methods asynchronously.

Step 8 Press F5 and see the output.

Enter the zip code in the textbox and click the go button.
