Introduction
Today, in this article let's dig out another interesting concept in Windows Phone of communicating via a WCF Service to perform some expected operation.
Question: What is Bing Map Direction Task?
In simple terms "It enables to find out route directions between requested source and destination, the requested places are displayed accordingly with distance (Miles/Kilometers) from source and clear way of directions to reach destination".
I think we all are now good to go and implement this interesting concept.
Step 1: The complete code of the IService1.cs looks like this.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace Wcf_Bing_Maps_Direction
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the interface name "IService1" in both code and config file together.
[ServiceContract]
public interface IService1
{
[OperationContract]
string To(string a);
}
}
Step 2: The complete code of the Service1.svc.cs looks like this.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace Wcf_Bing_Maps_Direction
{
// NOTE: You can use the "Rename" command on the "Refactor" menu to change the class name "Service1" in code, svc and config file together.
public class Service1 : IService1
{
public string To(string a)
{
return a;
}
}
}
Step 3: The complete code of the Web.Config looks like this.
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>
Step 4: The complete code of the MainPage.xaml looks like this.
<phone:PhoneApplicationPage

<!--Sample code showing usage of ApplicationBar-->
<!--<phone:PhoneApplicationPage.ApplicationBar>

</shell:ApplicationBar.MenuItems>
</shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>-->
</phone:PhoneApplicationPage>
Step 5: The complete code of the MainPage.xaml.cs looks like this.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using Microsoft.Phone.Tasks;
using System.Device.Location;
using Bing_Maps_Directions_Task.ServiceReference1;
namespace Bing_Maps_Directions_Task
{
public partial class MainPage : PhoneApplicationPage
{
// Constructor
public MainPage()
{
InitializeComponent();
}
void toCall(object sender, ToCompletedEventArgs e)
{
LabeledMapLocation from = new LabeledMapLocation("Hyderabad, Andhra Pradesh", null);
LabeledMapLocation to = new LabeledMapLocation(e.Result, null);
objDirectionTask.Start = from;
objDirectionTask.End = to;
objDirectionTask.Show();
}
private void button1_Click(object sender, RoutedEventArgs e)
{
textBlock3.Text = "";
if (string.IsNullOrEmpty(textBox2.Text))
{
textBlock3.Text = "Please Enter Values";
}
else
{
Service1Client objClient = new Service1Client();
objClient.ToCompleted += new EventHandler<ToCompletedEventArgs>(toCall);
objClient.ToAsync(textBox2.Text);
textBox2.Text = "";
}
}
#region object variables
BingMapsDirectionsTask objDirectionTask = new BingMapsDirectionsTask();
#endregion
}
}
Step 6: The output of the application looks like this.
Step 7: The Output To (Destination) Output Application looks like this.
